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: -Fascia, connective tissue outside the epimysium, surrounds and separates the muscles.

Detailed explanation-3: -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.

Detailed explanation-4: -There are three layers of connective tissue: epimysium, perimysium, and endomysium. Skeletal muscle fibers are organized into groups called fascicles. Blood vessels and nerves enter the connective tissue and branch in the cell. Muscles attach to bones directly or through tendons or aponeuroses.

Detailed explanation-5: -Fascia is a sheath of stringy connective tissue that surrounds every part of your body. It provides support to your muscles, tendons, ligaments, tissues, organs, nerves, joints and bones.
