MICROANATOMY

Detailed explanation-1: -Answer and Explanation: The correct answer is b. extensibility. The property of muscle that gives it the ability to stretch without damage is extensibility.

Detailed explanation-2: -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-3: -Extensibility: This is the ability of muscle tissue to stretch without being damaged and to allow muscle tissue to contract forcefully even it is already stretched.

Detailed explanation-4: -Extensibility is the ability to extend or stretch. Muscle cells shorten when contracting, but they can stretch, even beyond their resting length, when relaxed. Elasticity is the ability of a muscle cell to recoil and resume its resting length after stretching.

Detailed explanation-5: -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. If muscles are stretched, they recoil to their original resting length because of its elasticity.
