MUSCLE PHYSIOLOGY

Detailed explanation-1: -Each muscle is made up of groups of muscle fibers called fascicles surrounded by a connective tissue layer called perimysium. Multiple units of individual muscle fibers within each fascicle are surrounded by endomysium, a connective tissue sheath.

Detailed explanation-2: -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-3: -Each muscle fiber is surrounded by a thin layer of connective tissue called the endomysium.

Detailed explanation-4: -Each skeletal muscle is formed from several bundled fascicles of skeletal muscle fibers, and each fascicle is surrounded by perimysium ("peri"-around). Each single muscle cell is wrapped individually with a fine layer of loose (areolar) connective tissue called endomysium ("endo"-inside).
