MEDICAL PHYSIOLOGY

Detailed explanation-1: -Each bundle of muscle fiber is called a fasciculus and is surrounded by a layer of connective tissue called the perimysium. Within the fasciculus, each individual muscle cell, called a muscle fiber, is surrounded by connective tissue called the endomysium.

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

Detailed explanation-3: -Each muscle is made up of groups of muscle fibers called fascicles surrounded by a connective tissue layer called perimysium.

Detailed explanation-4: -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. It overlies the muscle fiber’s cell membrane: the sarcolemma.

Detailed explanation-5: -This connective tissue covering is known as the endomysium (endon-greek for within). The collagen fibres of these connective tissue wrappings merge with the tendons, aponeuroses, or periosteum-the dense connective tissue structures that link the muscle to bone, on which the muscle pulls.
