The cytoplasm of a skeletal muscle fiber is called the?
Sarcoplasm
Why is an individual skeleton muscle cell referred to as a muscle fiber?
An individual skeletal muscle cell is referred to as a muscle fiber because of its elongated, thread-like shape that resembles a fiber. These muscle fibers are multi-nucleated and contain specialized structures called myofibrils, which are responsible for contraction. The term "fiber" underscores the cell's role in forming the overall muscle tissue, emphasizing its function and structural characteristics.
What is the multinucleate muscle fiber?
Skeletal
What is a group of muscle cells called?
Muscle cells grouped together are called muscle tissue. The muscle cells contract and elongate to make the movement in the body parts. Muscle cells are found in several specialized forms such as Cardiac, skeletal or smooth muscles etc.Muscle cells grouped together are called muscle tissue.

What are the structures within the muscle fiber that shorten to cause skeletal muscle fiber contraction?
The structures within the muscle fiber that shorten to cause skeletal muscle contraction are called myofibrils. Myofibrils are composed of repeating units called sarcomeres, which contain thick and thin filaments made of proteins (actin and myosin). When the muscle fiber is stimulated by a nerve impulse, the myosin heads interact with the actin filaments to generate the force required for muscle contraction.
How relaxation in a skeletal muscle fiber occurs?
Relaxation of a skeletal muscle usually involves the Golgi tendon proprioceptors.
