Document Summary
Stimulation to do so can come from nerves, intrinsic system regulation,hormones, etc. Contain myofilaments (i. e. actin and myosin) which interact to produce tension. Helpful hint #1: prefixes myo or mys or sarco. Helpful hint #3: muscle cell = muscle fiber. Three types of muscle tissue: skeletal (voluntary, striated, cardiac (involuntary, striated, smooth (involuntary, nonstriated) Functions of muscle tissue: producing body movement including moving substances within the body (e. g. peristalsis); changing the size of certain structures (e. g. pupil of eye, maintaining posture, stabilizing joints, generating heat (thermogenesis) A skeletal muscle (i. e. the organ) contains: skeletal muscle fibers, blood vessels (artery, capillaries, and veins, nerve fibers, connective tissue. Connective tissue sheaths associated with a skeletal muscle (i. e. the organ): endomysium, perimysium, epimysium. Most skeletal muscles cross at least one joint and are usually attached to the articulating bones that form the joint.
