Document Summary

Prime mover: a muscle that produces a specific movement. Endomysium: fine layer of ct that surrounds each muscle fiber (cell) Epimysium: dense, fibrous ct that surrounds & holds together a group of fascicles = Perimysium: sheath around a fascicle outside layer of a single muscle. Deep fascia: still coarser layer of dense ct that binds muscles into functional groups eg: hamstrings vs quadriceps. Antagonists: a muscle that opposes or reverses a particular movement help regulate movement of a prime mover by adding resistance. Synergists: help prime movers by adding a little extra force to the same movement or by reducing undesirable or unnecessary movements. Fixators: when a synergist immobilizes a bone or a muscles origin so the prime mover has a stable base muscles that help maintain upright posture. Aponeurosis: anchors the muscle to the ct covering a muscle. Urogenital diaphragm: stretches between the two sides of the pubic arch in the anterior half of the perineum.
