MICROANATOMY

Detailed explanation-1: -The correct option is C fasciculus. A single bundle of muscle fibres is known as fasciculus (plural: fasciculi) 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: -The individual bundles of muscle fibers in a skeletal muscle are known as fasciculi. The outermost connective tissue sheath surrounding the entire muscle is known as epimysium.

Detailed explanation-3: -Overview. In anatomy, a fascicle is a bundle of skeletal muscle fibers surrounded by connective tissue. Specialized muscle fibers in the heart which transmit electrical impulses from the Atrioventricular Node (AV Node) to the Purkinje Fibers are fascicles, also referred to as bundle branches.

Detailed explanation-4: -A muscle fascicle is a bundle of skeletal muscle fibers surrounded by perimysium, a type of connective tissue.

Detailed explanation-5: -A nerve fascicle is also called a fasciculus. A nerve fascicle is enclosed by perineurium, a layer of fascial connective tissue. Each enclosed nerve fiber in the fascicle is enclosed by a connective tissue layer of endoneurium. Bundles of nerve fascicles are called fasciculi and are constituents of a nerve trunk.
