None of the above

Detailed explanation-1: -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. There are several types of muscle fiber, each with different characteristics.
Detailed explanation-2: -Skeletal muscle cells occur in the form of multinucleated fibers that can be up to several centimeters long. In the embryo, a skeletal muscle fiber begins as a single cell, called a myoblast.
Detailed explanation-3: -The place where a neuron makes contact with an individual muscle fiber is called a neuromuscular junction. The neuromuscular junction is basically a synapse: the neuron releases a neurotransmitter called acetylcholine (ACh) which binds to receptors on the sarcolemma (the cell wall of the muscle fiber).
