list three reasons why the connective tissue wrappings of the skeletal muscle are important.
supporting and binding the muscle fibers, providing strength to the muscle as a whole and to provide a route for the entry and exit of nerves and blood vessels that serve the muscle fibers.
why are there more indirect- that is, tendinous- muscle attachmens to bone than there are indirect attachments?
they can span rough bony prominences that would destroy the more delicate muscle tissues and because of their relatively small size, more tendons than muscles can pass over joints.
how does an aponeurosis differ from a tendon structurally?
tendons are strong and cord-like and attach muscle to bone; aponeurosis are sheet-like and attach muscle to muscle.
the junction between a motor neuron's axon and the muscle cell membrane is called?
within the axon terminal are many small vesicles containing a neurotransmitter substance called
when the _____ reaches the ends of the axon, the neurotransmitter is released and diffuses to the muscle cell membrane to combine with receptors there.
