Like connective tissue elsewhere, that of muscle consists of fibers embedded in an
amorphous ground substance. The connective in muscle has three anatomical parts, the epimysium, perimysium and endomysium.
Perimysium is a fibrous tissue that extends inward from the epimysium, surrounding bundles of muscles. Each bundle bound by perimysium is called a fascicle.
By light microscopy, individual muscle fibers are located within the fascicles, surrounded by perimysium and located within a compartment known as the endomysium.
The perimysium is tough and relatively thick; and it also provides the pathway for the major blood vessels and nerves to run through the muscle belly.
What is perimysium?
