MICROANATOMY

Detailed explanation-1: -Contractility refers to the capacity of muscle to contract or shorten forcefully. Muscles can be stretched to their normal resting length and beyond to a limited degree. This is because of extensibility.

Detailed explanation-2: -Flexibility has been defined as the range of motion of muscle and connective tissues at a joint or group of joints. In contrast to other, more general or systemic fitness components, flexibility is highly specific to each of the joints of the body.

Detailed explanation-3: -Extensibility-ability of a muscle to be stretched without tearing; Elasticity-ability to return to its normal shape.

Detailed explanation-4: -Extensibility is the ability of a muscle to be stretched. For instance, let’s reconsider our elbow flexing motion we discussed earlier. In order to be able to flex the elbow, the elbow extensor muscles must extend in order to allow flexion to occur. Lack of extensibility is known as spasticity.

Detailed explanation-5: -contractility. Solution. Muscles have some characteristics in common-irritability, extensibility, elasticity, and contractility. The ability of a muscle tissue to extend is called the extensibility, while the capability to revert to its initial length is elasticity.
