MICROANATOMY

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: -The endomysium, meaning within the muscle, is a wispy layer of areolar connective tissue that ensheaths each individual muscle fiber, or muscle cell. It also contains capillaries and nerves.

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

Detailed explanation-4: -The endomysium, a fine layer of connective tissue, wraps each muscle fiber and separates it from neighboring fibers. Another layer of connective tissue, the perimysium, surrounds a bundle of up to 150 fibers called a fasciculus. A fascia of fibrous connective tissue, the epimysium, surrounds the entire muscle.

Detailed explanation-5: -The epimysium is a thick connective tissue layer that is composed of coarse collagen fibers in a proteoglycan matrix. The epimysium surrounds the entire muscle and defines its volume. The arrangement of collagen fibers in the epimysium varies between muscles of different shapes and functions.
