Objective 1. Describe the 3 types of muscles. Three types of muscle waver: skeletal, cardiac, smooth Differ in cadre structure, body location, wreak, and the style by which they are activated to contract. Similar in that exclusively are elongated and contraction depends on 2 kinds of myofilaments.
wasted Muscle Tissue - Packaged into skeletal muscle that tie to and cover the bony skeleton. Visually obvious bands -- striations. Voluntary swear - subject to conscious control. Can contract rapidly and smartly but tire easily. Can exert tremendous power. unmistakably adaptable.
Cardiac Muscle Tissue - Found only in the heart. Striated and Involuntary. Gap junctions allow rapid communication between cells 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 alternating circular and longitudinal layers; synchronized contraction of the sheets leave alone rise to a wave of contraction along the hollow organ - peristalsis.
Objective 2. List the functions of muscle.
1. Movement - Just 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 Posture - Muscles function almost continuously making small adjustments to maintain an raise or seated posture despite the effects of gravity.
3. enounce Stability - Skeletal muscles help stabilize joints with poor strengthener or noncomplementary articular surfaces -- shoulder, knee.
4. Heat Generation - Generate erupt as the muscles contract. Vitally important in maintenance of habitual body temperature. Skeletal muscle are most responsible.
Objective 3. Describe the functional characteristics of muscle.
a. Excitability - Ability to receive and reply to a stimulus --...If you want to get a well(p) essay, order it on our website: Ordercustompaper.com
