Microscopic Anatomy And Organization Of Skeletal Muscle

Aponeuroses are thick membranes that separate muscles from one another. Within the axonal terminal are many small vesicles containing a neurotransmitter substance called 4.

Both aponeuroses and tendons are capable of resisting considerable tension.

Tendons are similar in both function and composition only they serve to connect muscles to bones. They are tough and resilient.

Add strength to muscle. Use the items on the right to correctly identify the structures described on the left. Microscopic anatomy and organization of skeletal muscle.

When the 5 reaches the end of axon the neurotransmitter is released and diffuses to the muscle cell membrane to combine with the recepotors there. The actual gap between the axonal terminal and the muscle cell is called a 3. Ach acetylcholine within the axon terminal are many small vesicles containing this neurotransmitter substance.

Composed of actin and myosin which slide past each other during muscle activity to bring about shortening and contracting of the muscle cells. Three reasons why the connective tissue wrappings of skeletal muscle are important. Microscopic anatomy and organization of skeletal muscle chapter 14.

Both aponeuroses and tendons are capable of resisting considerable tension. A motor neuron and all of the skeletal muscle cells it stimulates is called a 2. They are tough and resilient.
