PATHOLOGY

Detailed explanation-1: -As well as producing active contractile force, muscles are also passively elastic, which is essential to their performance. The origins of both active contractile and passive elastic forces can be traced to the individual proteins that make up the highly ordered structure of muscle.

Detailed explanation-2: -Muscles are all made of the same material, a type of elastic tissue (sort of like the material in a rubber band). Thousands, or even tens of thousands, of small fibers make up each muscle.

Detailed explanation-3: -The muscles of the human muscular system are composed of a kind of elastic tissue. Every movement in our body is the result of muscle contraction and is found in every organ, including the blood vessels, heart, digestive organs, etc.
