Document Summary

Terms to know: flexion/extension, decreasing the angle at a body part/increasing the angle, pronation/supination, when the foot rolls inward/foot rolls outward. Inversion/eversion: when the sole is brought towards the midline/sole twisted away, adduction/abduction, motion when a structure is pulled towards the midline/away from. Synergist one or more involved in movement; adding extra force or reducing undesirable movements; ie. how you want to ex your hands just wrist, just phalanges, all (a st: fixators muscles that help maintain upright posture; stabilizer; squat position. Muscle overview part 1: gross anatomy and function. Ct wrappings: epimysium overcoat of dense ct tissue surrounded entire muscle. Perimysium layer of dense irregular ct tissue surrounding fascicles in skeletal muscle. Endomysium surrounds each individual muscle bre within fascicles: origin. Insertion attachment on the movable bone: most attachments are indirect attachments involving either a tendon or an aponeurosis (for wide areas of attachment; sheet-like; replaces tendons) Circular: muscles with this arrangement surround external openings ie. eyes, mouth.
