MUSCLE PHYSIOLOGY

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: -Each bundle of muscle fiber is called a fasciculus and is surrounded by a layer of connective tissue called the perimysium.

Detailed explanation-3: -Skeletal Muscles Myofibers are grouped into larger units called muscle fascicles, which are enveloped together by connective tissue (called epimysium) into anatomically recognized muscles. Epimysium extends internally between fascicles, forming septa that are called perimysium.

Detailed explanation-4: -: a small or slender bundle (as of pine needles or nerve fibers) : one of the divisions of a book published in parts.

Detailed explanation-5: -When a group of muscle fibers is “bundled” as a unit within the whole muscle it is called a fascicle. Fascicles are covered by a layer of connective tissue called perimysium (see Figure 10.2. 1). Fascicle arrangement is correlated to the force generated by a muscle and affects the muscle’s range of motion.
