Anatomical terminology

Perimysium is a sheath of dense irregular connective tissue that groups muscle fibers into bundles (anywhere between 10 and 100 or more) or fascicles.

Contents

Studies of muscle physiology suggest that the perimysium plays a role in transmitting lateral contractile movements. This hypothesis is strongly supported in one exhibition of the existence of "perimysial junctional plates" in ungulate flexor carpi radialis muscles. [1] The overall comprehensive organization of the perimysium collagen network, as well as its continuity and disparateness, however, have still not been observed and described thoroughly everywhere within the muscle.[ citation needed ] It contains mainly type I collagen, then type III and V in descending order. [2]
