WebSkeletal muscles contain connective tissue, blood vessels, and nerves. There are three layers of connective tissue: epimysium, perimysium, and endomysium. Skeletal muscle fibers are organized into groups called fascicles. Blood vessels and nerves enter the connective tissue and branch in the cell. WebGood experimental evidence shows that perimysium and epimysium are capable in some circumstances to act as pathways for myofascial force transmission.

WebEach muscle is surrounded by a connective tissue sheath called the epimysium. Fascia, connective tissue outside the epimysium, surrounds and separates the muscles. Portions of the epimysium project inward to divide the muscle into compartments. Each compartment contains a bundle of muscle fibers. WebFibrous sheaths that surround the fascicles are called the perimysium (peri is greek for around). Blood vessels, the lymphatics and the nerves are all found in the perimysium. Each muscle fibre is surrounded by loose … WebFascia (or deep fascia) is a layer of thickened connective tissue that covers the entire muscle and is located over the layer of epimysium.
