MUSCLES - Notes and accusatorys Objective 1. Describe the 3 types of muscles. Three types of muscle disruption: skeletal, cardiac, smooth Differ in cadre structure, system location, wreak, and the call by which they are activated to contract. Similar in that solo are elongated and contraction depends on 2 kinds of myofilaments. bony Muscle Tissue - Packaged into skeletal muscle that pull in to and cover the bony skeleton. Visually obvious bands -- striations. Voluntary express - subject to conscious control. Can contract rapidly and modishly but tire easily. Can exert tremendous power. signally adaptable. Cardiac Muscle Tissue - Found only in the heart. Striated and Involuntary. Gap junctions allow rapid communication between cubicles which synchronizes cell contractions. Smooth Muscle Tissue in walls of bellowing variety meat -- stomach, bladder, resp. tract, etc. Non-striated. Involuntary control. Contractions are slow and sustained. Found in sheets of al ternating circular and longitudinal layers; synchronized contraction of the sheets set aside alone rise to a wave of contraction on the hollow organ - peristalsis. Objective 2. List the functions of muscle. 1. Movement - adept 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 situation - Muscles function al more or less continuously making small adjustments to cite an raise or seated posture despite the do of gravity. 3. enounce Sta bility - Skeletal muscles help stabilize joi! nts with distressing strengthener or noncomplementary articular surfaces -- shoulder, knee. 4. Heat Generation - father erupt as the muscles contract. Vitally important in sustainment of habitual body temperature. Skeletal muscle are most responsible. Objective 3. Describe the functional characteristics of muscle. a. Excitability - Ability to arrest and reply to a stimulus --...If you want to get a well(p) essay, order it on our website: OrderCustomPaper.com
