4.elasticity

Answer 2

The fundamental characteristics of muscles are ​exicitability, contractility, extensibility and elasticity.

Explanation:

1) Contractility:Muscle cells' contractility refers to their capacity to forcibly shorten. To flex (lower the angle of a joint) your elbow, for example, you must contract (shorten) the biceps brachii and other anterior arm elbow flexor muscles. It's worth noting that contracting the posterior arm extensor muscles is required to extend your elbow. Muscles can only pull, not push, as a result.

2) Excitability: The capacity to respond to a stimulus, which might be from a motor neuron or a hormone, is known as excitability.

3) Extensibility: A muscle's extensibility refers to its capacity to be stretched. Let's take a look at the elbow flexing action we mentioned before. To flex the elbow, the extensor muscles of the elbow must extend.

4) Elasticity: After being stretched, elasticity refers to the muscle's capacity to rebound or bounce back to its previous length.1)
