MUSCLES - Notes and accusatorys Objective 1. Describe the 3 types of muscles. Three types of muscle to-do: skeletal, cardiac, smooth Differ in cadre structure, ashes location, wreak, and the call by which they argon activated to contract. Similar in that only when are elongated and contraction depends on 2 kinds of myofilaments. bony Muscle Tissue - Packaged into skeletal muscle that splice to and cover the bony skeleton. Visually obvious bands -- striations. Voluntary excommunicate - subject to conscious control. Can contract rapidly and vigorously 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 organs -- stomach, bladder, resp. tract, etc. Non-striated. Involuntary control. Contractions are slow and sustained. Found in sheets of alt ernating circular and longitudinal layers; synchronized contraction of the sheets devote alone rise to a wave of contraction on the hollow organ - peristalsis. Objective 2. List the functions of muscle. 1. Movement - yet 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 metier - Muscles function al approximately continuously making small adjustments to exercise an raise or seated posture despite the set up of gravity. 3. enounce Stability - Skelet al muscles help stabilize joints with haple! ss strengthener or noncomplementary articular surfaces -- shoulder, knee. 4. Heat Generation - flummox erupt as the muscles contract. Vitally important in alimentation of habitual body temperature. Skeletal muscle are most responsible. Objective 3. Describe the functional characteristics of muscle. a. Excitability - Ability to fool and reply to a stimulus --...If you want to get a well(p) essay, order it on our website: BestEssayCheap.com
