Anatomical terminology

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 constructed by Emilie Passerieux.[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. Found to have type I, III, VI, and XII collagen.
