BIO-203 Chapter Notes - Chapter 9: Sarcolemma, Aponeurosis, Perimysium
Document Summary
What"s the relationship of these sheaths to the tendons at the ends of the muscle: sarcolemma plasma membrane, endomysium a wispy sheath of connective tissue that surrounds each individual muscle fiber, fascicle muscle fiber groups resemble a bunch of sticks, perimysium surround each fascicle a layer of fibrous ct, epimysium an overcoat of dense irregular ct that surrounds the whole muscle, deep fascia lies between neighboring muscles i. Define the following as they refer to muscles: origin, insertion, tendon, aponeurosis, prime mover, antagonist, and synergist: when a muscle contracts, the moveable bone, the muscle"s insertion, moves towards the immovable or less movable bone, the muscle"s origin, tendon ct that extends beyond the muscle as a ropelike attachment mostly tough collagen fibers which can withstand the abrasion of rough bony projections that would tear apart more delicate muscle tissues tendons conserve space bc of their small size, aponeurosis ct that extends beyond the muscle as a sheet i.
