MICROANATOMY

Detailed explanation-1: -Explanation: Skeletal muscle fiber is referred to as a skeletal muscle cell. Inside each of these fibers are present long cylindrical structures called myofibrils . Many oval nuclei are found just beneath the plasma membrane (known as sarcolemma) of the muscle fiber.

Detailed explanation-2: -Skeletal muscle cells are long, cylindrical, and striated. They are multi-nucleated meaning that they have more than one nucleus. This is because they are formed from the fusion of embryonic myoblasts. Each nucleus regulates the metabolic requirements of the sarcoplasm around it.

Detailed explanation-3: -Skeletal muscle fibers are cylindrical, multinucleated, striated, and under voluntary control.

Detailed explanation-4: -Within each muscle fiber are myofibrils-long cylindrical structures that lie parallel to the muscle fiber.

Detailed explanation-5: -Each skeletal muscle fiber is a single cylindrical muscle cell. An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering. Each muscle is surrounded by a connective tissue sheath called the epimysium.
