MUSCLE PHYSIOLOGY

Detailed explanation-1: -Each 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.

Detailed explanation-2: -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.

Detailed explanation-3: -Each muscle is wrapped in a sheath of dense, irregular connective tissue called the epimysium, which allows a muscle to contract and move powerfully while maintaining its structural integrity. The epimysium also separates muscle from other tissues and organs in the area, allowing the muscle to move independently.

Detailed explanation-4: -Each muscle fiber is surrounded by a thin layer of connective tissue called the endomysium.
