The breasts, themselves, do not contain muscles. As in males, the pectoralis major and minor underlie the breast tissue.
Muscles contain the most glycogen..........
When muscles are stimulated, they contract, causing the muscle to become shorter. The force applied is therefore a tension. Most muscles are arranged in pairs so that each can apply tension to move a joint in either direction. Obvious examples of the pairing of muscles can be seen at the elbow and knee.

Passive insufficiency occurs when a muscle cannot be elongated any farther.
The axon, an elongated portion of the neuron, carries impulses to the muscles.
They are orientated at right angles to one another
