The endomysium, literally meaning within the muscle, is a layer of connective tissue that ensheaths a muscle fiber and is composed mostly from reticular fibers. It also contains capillaries, nerves and lymphatics.

The term "cardiac skeleton" is sometimes considered synonymous with endomysium, but sometimes it refers to the combination of the endomysium and perimysium.
