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

Studies of muscle physiology suggest that the perimysium plays a role in [[Lateral force transmission in skeletal muscle|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.<ref>{{cite journal |title=Structural organization of the perimysium in bovine skeletal muscle: Junctional plates and associated intracellular subdomains |journal=Journal of Structural Biology |volume=154 |number=2 |pages=206–216 |year=2006 |issn=1047-8477 |doi=10.1016/j.jsb.2006.01.002 |author=E.

Found to have type I, III, VI, and XII collagen.
