Muscle Structure

What are the four major characteristics of skeletal muscle?

The four major functional characteristics of skeletal muscle are:

Contractility—The ability to shorten which causes movement of the structures to which the muscles are attached.

Excitability—The ability to respond or contract in response to chemical and/or electrical signals.

Extensibility—The capacity to stretch to the normal resting length after contracting

Elasticity—The ability to return to the original resting length after a muscle has been stretched.
