Study Notes
Muscle Tissue Properties
-
Excitability: Muscles respond to stimuli, like nerve impulses. A motor neuron signal causes muscle contraction (e.g., biceps brachii contracting).
-
Contractility: Muscles shorten in response to stimulation. Elbow flexion shortens the biceps brachii.
-
Extensibility: Muscles can be stretched without tearing. Gymnast's splits demonstrate muscle extensibility.
-
Elasticity: Muscles return to their original length after stretching. After stretching, muscles don't remain in a shortened state.
