GENERAL HISTOLOGY

Detailed explanation-1: -Elasticity– The muscles have the ability to recoil back to its original length after being stretched. Excitability– The muscle tissue responds to a stimulus delivered from a motor neuron or hormone.

Detailed explanation-2: -A muscle can return to its original length when relaxed due to a quality of muscle tissue called elasticity. It can recoil back to its original length due to elastic fibers. Muscle tissue also has the quality of extensibility; it can stretch or extend.

Detailed explanation-3: -Extensibility is the ability of a muscle to be stretched or extended. Elasticity is the ability to a muscle to return to its original length when relaxed.

Detailed explanation-4: -Muscle elasticity increases with aging and there is evidence suggesting that titin (encoded by the TTN gene), a protein that is expressed in cardiac and skeletal muscles, is one of the factors responsible for elastic properties of the muscles.
