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

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]
