[] Muscle is a found in most animals. Contain filaments of and that slide past one another, producing a that changes both the length and the shape of the cell.

Muscles function to produce force and. They are primarily responsible for maintaining and changing,, as well as movement of, such as the contraction of the and the movement of food through the via. Are derived from the layer of embryonic in a process known as.

The muscle in the front of the stomach that form the six-pack when one's body fat is fairly low. Their function is to draw the base of the ribcage and the hips towards each other, as. Whey protein has the highest biological value of any protein. The higher the biological value, the.Missing.

There are three types of muscle, or striated,, and. Muscle action can be classified as being either voluntary or involuntary. Cardiac and smooth muscles contract without conscious thought and are termed involuntary, whereas the skeletal muscles contract upon command. Skeletal muscles in turn can be divided into fast and slow twitch fibers.

Muscles are predominantly powered by the of and, but chemical reactions are also used, particularly by fast twitch fibers. These chemical reactions produce (ATP) molecules that are used to power the movement of the myosin heads. The term muscle is derived from the Latin musculus meaning 'little mouse' perhaps because of the shape of certain muscles or because contracting muscles look like mice moving under the skin. The body contains three types of muscle tissue: (a) skeletal muscle, (b) smooth muscle, and (c) cardiac muscle. (Same magnification) is a, and is one of the four fundamental types of present in animals.

There are three types of muscle tissue recognized in: • or 'voluntary muscle' is anchored by (or by at a few places) to and is used to effect movement such as and in maintaining posture. Though this postural control is generally maintained as an unconscious reflex, the muscles responsible react to conscious control like non-postural muscles. An average adult male is made up of 42% of skeletal muscle and an average adult female is made up of 36% (as a percentage of body mass). • or 'involuntary muscle' is found within the walls of organs and structures such as the,,,,,,,, and the in the skin (in which it controls erection of body hair). Unlike skeletal muscle, smooth muscle is not under conscious control. • (myocardium), is also an 'involuntary muscle' but is more akin in structure to skeletal muscle, and is found only in the heart.

Cardiac and skeletal muscles are 'striated' in that they contain that are packed into highly regular arrangements of bundles; the myofibrils of smooth muscle cells are not arranged in sarcomeres and so are not striated. While the sarcomeres in skeletal muscles are arranged in regular, parallel bundles, cardiac muscle sarcomeres connect at branching, irregular angles (called intercalated discs). Striated muscle contracts and relaxes in short, intense bursts, whereas smooth muscle sustains longer or even near-permanent contractions.

Skeletal (voluntary) muscle is: and: •, or 'red' muscle, is dense with and is rich in and, giving the muscle tissue its characteristic red color. Download Kits Fifa 14. It can carry more and sustain activity using fats or carbohydrates as fuel. Easy Tool For Keygen Crack on this page. Slow twitch fibers contract for long periods of time but with little force. •, has three major subtypes (IIa, IIx, and IIb) that vary in both contractile speed and force generated. Fast twitch fibers contract quickly and powerfully but fatigue very rapidly, sustaining only short, bursts of activity before muscle contraction becomes painful. They contribute most to muscle strength and have greater potential for increase in mass.

Type IIb is anaerobic,, 'white' muscle that is least dense in mitochondria and myoglobin. In small animals (e.g., rodents) this is the major fast muscle type, explaining the pale color of their flesh. The of mammalian skeletal muscle tissue is about 1.06 kg/liter. This can be contrasted with the density of (fat), which is 0.9196 kg/liter.
