MUSCLE PHYSIOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -The outermost connective tissue sheath surrounding the entire muscle is known as epimysium. The connective tissue sheath covering each fasciculus is known as perimysium, and the innermost sheath surrounding individual muscle fiber is known as endomysium.

Detailed explanation-3: -This connective tissue covering is known as the endomysium (endon-greek for within). The collagen fibres of these connective tissue wrappings merge with the tendons, aponeuroses, or periosteum-the dense connective tissue structures that link the muscle to bone, on which the muscle pulls.

Detailed explanation-4: -Epimysium (plural epimysia) (Greek epi-for on, upon, or above + Greek mys for muscle) is the fibrous tissue envelope that surrounds skeletal muscle. It is a layer of dense irregular connective tissue which ensheaths the entire muscle and protects muscles from friction against other muscles and bones.
