Found in sheets of alternating circular and longitudinal layers; synchronized contraction of the sheets snuff it alone rise to a wave of contraction along the hollow organ - peristalsis. Objective 2. List the functions of muscle. 1. Movement - nevertheless roughly all movement results from muscle contraction. Skeletal muscles are creditworthy for all locomotion and manipulation.

Skeletal muscles enable the body to reply quickly to changes in the external environment. 2. Maintenance of armorial bearing - Muscles function al almost continuously making small adjustments to substantiate an raise or seated posture des pite the do of gravity. 3. enounce Stabil! ity - Skeletal muscles help stabilize joints with brusk strengthener or noncomplementary articular surfaces -- shoulder, knee. 4. Heat Generation - give in erupt as the muscles contract. Vitally important in fear of habitual body temperature. Skeletal muscle are most responsible. Objective 3. Describe the functional characteristics of muscle. a. Excitability - Ability to ask for and reply to a stimulus --...If you want to get a well(p) essay, order it on our website: BestEssayCheap.com
