Research Paper On Skeletal Muscle

Movement of the skeleton is stimulated by the contraction of striated muscle also known as skeletal muscle. Because it is attached to the bones and skin it is responsible for the motion of the body and limbs, thus making it controlled voluntarily. There are three layers of connective tissue in the skeletal muscle known as epimysium which surrounds the entire muscle, perimysium which surrounds muscle fibers known as fascicles, and endomysium which contains capillaries and nerve fibers.
Cardiac muscle is found in the heart, also striated but is involuntary meaning it beats on its own without stimulation. They are also more dependent on aerobic metabolism for the energy they use to continue contracting.
Smooth muscle known as nonstriated muscle is an involuntary muscle found in the walls of the blood vessels and different hollow organs. Around blood vessels it regulate blood flow through vital organs, in the digestive and urinary systems around the rings called sphincter, assist in the movement of materials along the passageway …show more content…
The majority of the skeletal muscle fibers are considered fast fibers because of the ability to reach peak twitch tension in 0.01 second or less after stimulation. Although large in diameter with also large glycogen content, fast fibers use considerable amount of energy which makes it exhausted faster. With half the diameter as fast fibers, slow fibers have high level of endurance and functions primarily in the presence of aerobic metabolism. Meaning it requires oxygen which allows for longer productivity. (Martini, 2014. p. 320). Similar to fast fibers, intermediate fibers are pale in color and have less myoglobin. Being more resistant to fatigue and not being able to easily slow down, the intermediate fibers is also
