MUSCLE PHYSIOLOGY

Detailed explanation-1: -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-2: -1. The epimysium is the dense connective tissue that surrounds the entire muscle tissue. The epimysium usually contains many bundles (fascicles) of muscle fibers. 2. The perimysium is the connective tissue that surrounds each bundle of muscle fibers.

Detailed explanation-3: -Note: The perimysium is the loose connective tissue that surrounds each bundle of muscle fibers. The endomysium is a fine and delicate layer of areolar connective tissue that encases each muscle fiber. It also contains capillaries, nerves, and lymphatics.
