Cardiac deffinition tissue, is found only in the walls of the heart as myocardiumand is Natural antioxidant foods involuntary muscle controlled by the autonomic nervous system.
Cardiac muscle tissue is musce like skeletal muscle, containing contractile units called sarcomeres in highly regular arrangements of bundles. While ,uscle muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles known dedinition intercalated discs.
Smooth muscle tissue is Devining and involuntary. Smooth muscle is found within the walls of organs and structures such as the esophagusstomachintestinesbronchiuterusurethrabladderblood vesselsand the arrector pili in the skin which controls the erection of body hair.
Skeletal muscle is broadly classified into two fiber types: Type I slow-twitchand Type II fast-twitch muscle. The density of mammalian skeletal muscle tissue is about 1.
Skeletal muscle is a highly oxygen consuming tissue, and oxidative DNA damage that is induced by reactive oxygen species tends to accumulate with age. Smooth muscle is involuntary and non-striated. It is divided into two subgroups: the single-unit unitary and multiunit smooth muscle.
Within single-unit cells, the whole bundle or sheet contracts as a syncytium i. a multinucleate mass of cytoplasm that is not separated into cells. Multiunit smooth muscle tissues innervate individual cells; as such, they allow for fine control and gradual responses, much like motor unit recruitment in skeletal muscle.
Smooth muscle is found within the walls of blood vessels such smooth muscle specifically being termed vascular smooth muscle such as in the tunica media layer of large aorta and small arteriesarterioles and veins. Smooth muscle is also found in lymphatic vessels, the urinary bladderuterus termed uterine smooth musclemale and female reproductive tractsgastrointestinal tractrespiratory tractarrector pili of skinthe ciliary muscleand iris of the eye.
The structure and function is basically the same in smooth muscle cells in different organs, but the inducing stimuli differ substantially, in order to perform individual effects in the body at individual times. In addition, the glomeruli of the kidneys contain smooth muscle-like cells called mesangial cells.
Cardiac muscle is involuntary, striated muscle that is found in the walls and histological foundation of the heartspecifically the myocardium. The cardiac muscle cellsalso called cardiomyocytes or myocardiocytespredominantly contain only one nucleus, although populations with two to four nuclei do exist.
This complex mechanism illustrates systole of the heart. Cardiac muscle cells, unlike most other tissues in the body, rely on an available blood and electrical supply to deliver oxygen and nutrients and remove waste products such as carbon dioxide.
The coronary arteries help fulfill this function. All muscles are derived from paraxial mesoderm. The paraxial mesoderm is divided along the embryo 's length into somitescorresponding to the segmentation of the body most obviously seen in the vertebral column. The myotome is divided into two sections, the epimere and hypomere, which form epaxial and hypaxial musclesrespectively.
The only epaxial muscles in humans are the erector spinae and small intervertebral muscles, and are innervated by the dorsal rami of the spinal nerves. All other muscles, including those of the limbs are hypaxial, and innervated by the ventral rami of the spinal nerves.
During development, myoblasts muscle progenitor cells either remain in the somite to form muscles associated with the vertebral column or migrate out into the body to form all other muscles.
Myoblast migration is preceded by the formation of connective tissue frameworks, usually formed from the somatic lateral plate mesoderm. Myoblasts follow chemical signals to the appropriate locations, where they fuse into elongate skeletal muscle cells.
The primary function of muscle tissue is contraction. The three types of muscle tissue skeletal, cardiac and smooth have significant differences. However, all three use the movement of actin against myosin to create contraction. In skeletal muscle, contraction is stimulated by electrical impulses transmitted by the motor nerves.
Cardiac and smooth muscle contractions are stimulated by internal pacemaker cells which regularly contract, and propagate contractions to other muscle cells they are in contact with. All skeletal muscle and many smooth muscle contractions are facilitated by the neurotransmitter acetylcholine.
Smooth muscle is found in almost all organ systems such as hollow organs including the stomachand bladder ; in tubular structures such as blood and lymph vesselsand bile ducts ; in sphincters such as in the uterus, and the eye.
In addition, it plays an important role in the ducts of exocrine glands. It fulfills various tasks such as sealing orifices e. pylorus, uterine os or the transport of the chyme through wavelike contractions of the intestinal tube. Smooth muscle cells contract more slowly than skeletal muscle cells, but they are stronger, more sustained and require less energy.
Smooth muscle is also involuntary, unlike skeletal muscle, which requires a stimulus. Cardiac muscle is the muscle of the heart. It is self-contracting, autonomically regulated and must continue to contract in a rhythmic fashion for the whole life of the organism.
Hence it has special features. There are three types of muscle tissue in invertebrates that are based on their pattern of striation : transversely striated, obliquely striated, and smooth muscle. Contents move to sidebar hide. Article Talk. Read Edit View history. Tools Tools.

: Defining muscle definition| Build Muscle | The overweight group showed a much lower ability to generate the biological activity necessary for muscle building in response to a protein-rich meal, and the obese group had even more trouble. What the researchers saw was that the overweight group showed a much lower ability to generate the biological activity necessary for muscle building in response to a protein-rich meal, and the obese group had even more trouble. So what exactly does this mean for our question-asker, Erin? As simple as this sounds, the key here is a little more tricky. And that means two things—she needs to lose weight slowly and she needs to exercise and eat in a way that supports her muscles. One key factor in losing body fat while maintaining muscle mass is the speed of weight loss. A big reason why I co-founded the weight loss program called Weighless. Life is that most diets encourage you to lose weight too quickly. We have found that matching the rate of weight loss to one that matches the pace of actual fat loss about pounds per month is a huge game-changer for everyone, including athletes who are looking to either hit their optimal race weight or get that well-defined look. Yes, I know, you want to lose weight now. Cool, right? Now, I am going to defer to an article from my partner in the Weighless program, Monica Reinagel. Again, incorporating high-quality protein into every meal can help build lean muscle tissue and may also help with weight maintenance. The typical middle-aged American male eats about 90 grams of protein, which is enough to maximize muscle protein synthesis or muscle building. In the US and likely Canada, too people eat about 42 percent of their daily protein at dinner and only 16 percent at breakfast. To quote from another episode of Nutrition Diva, called How to Slow Age-Related Muscle Loss :. As we get older it takes a little more protein to hit that peak—about 30 grams at a single meal. So, whether you are in the fat-loss or the muscle-gain part of periodization, instead of hitting that peak dose of protein only once per day, focus on hitting it three times a day. In terms of hanging onto muscle mass as you lose fat, this could really help make a difference. After the fat loss phase is complete, switch your focus to muscle gain. I have articles and podcast episodes that highlight some of the best ways to gain muscle. The latest is an episode about whether or not you need to lift to failure every time you do resistance training. At all other times, lift just below failure 20 percent below, to be exact. This will help shorten the recovery time and allow you to return to your workouts sooner and with more energy and focus. You could also try some more interesting techniques like occlusion training. There is also a great muscle-building strategy called drop sets. This is a lifting protocol that allows you to go beyond your failure point by removing weights from the bar or machine each time you reach failure. Another great strategy is to lift heavy weights using full-body exercises like squats, deadlifts, presses, weighted pulls, and power lifts like the clean-and-push press. Doing these full-body exercises is a great way to build more muscle. It allows you to lift heavier loads than with a single-joint exercise like a bicep curl. PRO TIP! If you have access to a scale that measures body fat as you gain muscle, keep an eye out for a rise in fat. Fitness is all about being able to move through this world with as few limitations as possible. This site uses Akismet to reduce spam. Learn how your comment data is processed. However, these are advanced workouts that you shouldn't attempt if you are a beginner, and they may not do much in terms of specifically increasing your muscle tone and definition. Boot camp workouts use simple moves and often are designed for beginner- and intermediate-level exercisers. You typically can find boot camps or other HIIT training programs at your local gym or fitness center. Work out for at least 30 minutes. Most bodies use carbohydrate stores exclusively for the first 15 to 20 minutes of moderate-intensity exercise. If you keep going after that point, your body will start burning fat. Not only will you have lower body fat and more defined muscles, but you'll also be at lesser risk for heart attack or stroke. Good fat-burning cardio exercise can be as simple as jogging on the treadmill or outside, if the weather's nice. If you need more variety, check out aerobics classes at your local gym or fitness center. Do cardio exercises 5 to 6 days each week. While strength training builds muscle, cardio sessions focus on burning fat. Using cardio and strength training together is the best way to achieve maximum muscle tone and definition. For example, it might be easier for you to get your cardio in by going for a run early in the morning, and then doing your strength training after work. Another option is to plan your training sessions for an hour, and alternate between cardio and strength training in minute intervals. Extend cardio sessions on days you aren't strength training. Consider doing 45 to 60 minutes instead of 30 minutes to lose more fat and define your muscles; however, overtraining can be very hard on your body, so take 1 to 2 days of rest each week. You might also consider doing yoga on your off days to replace your regular weight training. While yoga will work your muscles, it's generally not considered as intense as weight training, so a light routine would be appropriate for your rest days. Part 2. Strength train for at least 30 minutes 3 or 4 days each week. You won't build muscle definition if you only strength train for 15 or 20 minutes once or twice a week. To get the tone you want, you must make a commitment to hit the gym on a more frequent basis. You can do the research and set up a routine on your own, but the easiest way to create your routine is to schedule a session with a certified personal trainer. They can not only advise you on exercises to do that will meet your goals, but also critique your form and technique. Typically, you'll get best results by focusing on your upper body the first day, your lower body the second day, and your core the third day. If you're strength training on a four day rotation, split your core over each of the 4 days and do 2 upper-body days and 2 lower-body days. Take 36 to 48 hours of rest between strength-training sessions. If you are doing your exercises correctly, you will tear a lot of muscle fibers. Your body needs time to repair your muscles and rebuild them so they are stronger. For example, you might do upper body 1 day, lower body the next day, You typically can do core strengthening exercises with only 24 hours of rest before the next strength-training session. Adequate rest also means getting adequate sleep. Your body is rebuilding muscle while you sleep, so make sure you get between 7 and 9 hours of restful sleep each night. Choose the right weight amount. You should be strength training with a weight heavy enough that you can only complete an exercise with correct form for 12 to 15 repetitions. The argument used to be that you used heavier weights to gain mass and did higher repetitions with lighter weights for tone and definition; however, modern training suggests there is a happy medium. Combining bulk or power training with high-rep strength training also can work well to get you the definition you want. For example, you might do a heavy, power upper-body strength training session on day one. The next day, do a similarly heavy lower-body strength training session. Take a day off, then do an upper-body strength training session with lower weights at higher repetitions. Follow up the next day with a similar lower-body session. Focus on good form and technique. Move slowly through the pushing and pulling motions, emphasizing quality over quantity. Especially if you're just starting, don't worry about how many reps you can do. Instead, make sure you have solid, consistent technique. Think in terms of actively lowering or pulling back the weight, not simply dropping it. Get a personal trainer or an experienced weight lifter to check and critique your form. Keep in mind that poor technique and sloppy form doesn't just mean your training is less effective, it also puts you at risk for injury. Do supersets, alternating between push and pull motions. Organize your strength-training routine so that you're doing 3 or 4 sets of 12 to 15 repetitions of each exercise. Rest for 30 seconds to 1 minute between each superset. When you alternate between pushing and pulling motions, you work different parts of the muscle. This gives the portion of the muscle you previously worked a little extra time to recover, so you can take a shorter rest break between sets. Bring your muscles to fatigue. When you push your muscles to the max you stimulate hypertrophy, which increases the volume of your muscles. This not only builds muscle mass, but also will improve their definition. If they don't, you need to add more weight. Make sure you're doing simple exercises, such as pushups or dumbbell presses, that you can control and complete in good form even when your muscles are exhausted. Work as many muscles together as possible. Don't work your biceps without working your triceps, shoulders, back, and chest. You won't achieve good resting definition unless your whole body is being worked hard. Ignoring surrounding muscles in favor of the major ones, such as biceps, can lead to muscle imbalances that will significantly increase your risk for injury. Aim to work an entire muscle group with each exercise. If you don't know a lot of different exercises, sign up for a few sessions with a personal trainer. They can help you create a well-rounded workout. Don't just work the muscles you see in the mirror. You may not think about working out your back because you can't see it, but remember that everyone else can! Part 3. Make diet a priority. Generally, you should eat more protein and lay off foods that are high in fat and simple carbohydrates. Instead of eating 3 big meals a day, try to eat 5 or 6 smaller meals, so that you're eating once every 2 to 3 hours. Plan your meals so that 40 percent of your calories are coming from protein, while you limit fats and carbohydrates to 30 percent each. At least 85 percent of the carbohydrates you eat should come from vegetables, with the rest coming from complex carbohydrates such as fruits, whole grains, nuts, and seeds. Eat or drink a protein-rich snack before and after your workout. Protein helps rebuild muscle and will help ensure a faster recovery. Try a protein shake, an apple with peanut butter, chicken, nuts, Greek yogurt or cottage cheese. Whole food typically works better for your pre-workout snack. A protein shake may work better post-workout, especially if you find it difficult to eat after an intense workout. Whey protein is one of the best sources of complete protein, because it includes all the essential amino acids you need to rebuild your muscles. You can buy whey protein in powder form and blend it into shakes yourself, or you can buy pre-made protein shakes at grocery or health food stores. Eat ancient grains. Quinoa, spelt, oat bran, amaranth, and other ancient grains are high in protein and minerals, which may help to promote muscle growth by supplying your body with the necessary nutrition. You also can find bread made from these grains at organic or natural grocery stores. Drink more water before, during and after a workout. Dehydration decreases your performance and can put you at risk for injury, as well as make recovery more difficult. While strength training, you shouldn't lose more than 2 percent of your body weight in fluid. The difference between the 2 weights is the amount of fluid you've lost. For each pound of fluid you lose, you must drink between 20 to 24 fluid ounces to mL of water to replace it. Replacement of lost water is sufficient to keep you hydrated provided you were hydrated to begin with. To determine this for certain, check your urine. If it's clear, you're well hydrated.
