MICROANATOMY

Detailed explanation-1: -Each skeletal muscle consists of thousands of muscle fibers wrapped together by connective tissue sheaths. 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-2: -Skeletal muscle cells Muscle cells, commonly known as myocytes, are the cells that make up muscle tissue. Skeletal muscle cells are long, cylindrical, multi-nucleated and striated. Skeletal muscle cells have high energy requirements, so they contain many mitochondria in order to generate sufficient ATP.

Detailed explanation-3: -Skeletal muscle fibers are broadly classified as “slow-twitch” (type 1) and “fast-twitch” (type 2).

Detailed explanation-4: -Each skeletal muscle fiber is innervated by a single motor axon. The same axon may also innervate other muscle fibers. All the fibers innervated by the same axon are called a motor unit.

Detailed explanation-5: -Muscle tissue contains something called muscle fibers. Muscle fibers consist of a single muscle cell. They help to control the physical forces within the body. When grouped together, they can facilitate organized movement of your limbs and tissues.
