GENERAL HISTOLOGY

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. If muscles are stretched, they recoil to their original resting length because of its elasticity.

Detailed explanation-2: -Muscle extensibility: ability of a muscle to extend to a predetermined endpoint. When referring to human studies, “extensibility” assumes an endpoint of subject sensation unless otherwise noted. Muscle Length Dimension.

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: -The passive extensibility of skeletal muscles can be defined as the ability of skeletal muscles to lengthen without muscle activation. Passive extensibility is an important component of total muscle function because it allows for the maximal length of both non-activated and activated muscles.
