ANATOMY

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: -Each muscle is surrounded by a connective tissue sheath called the epimysium.

Detailed explanation-3: -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-4: -The periosteum, endosteum and perichondrium are all layers of tissue in and around your bones. The periosteum is the sheath outside your bones that supplies them with blood, nerves and the cells that help them grow and heal.

Detailed explanation-5: -Each fascicle is wrapped in connective tissue: the perimysium. The process is repeated within the fascicle, with each muscle fibre surrounded by an endomysium. Blood vessels and nerve fibres enter the muscle via this connective tissue network.
