MICROANATOMY

Detailed explanation-1: -Myofibers are grouped into larger units called muscle fascicles, which are enveloped together by connective tissue (called epimysium ) into anatomically recognized muscles. Epimysium extends internally between fascicles, forming septa that are called perimysium .

Detailed explanation-2: -A nerve fascicle is also called a fasciculus. A nerve fascicle is enclosed by perineurium, a layer of fascial connective tissue. Each enclosed nerve fiber in the fascicle is enclosed by a connective tissue layer of endoneurium. Bundles of nerve fascicles are called fasciculi and are constituents of a nerve trunk.

Detailed explanation-3: -The number of fascicles in a muscle ranged from 61 to 101 fascicles per whole muscle. During dissection it was observed that the fascicles did not always run from distal to proximal tendon, that some fascicles were in series, and that they were not the same length as the whole muscle.
