Only one but there are several divisions of it such as central vs peripheral or sympathetic vs parasympathetic nervous system. It's all one but different ways of dividing it up to make sense of it.

What are nerves and muscle fibers?

A nerve fiber is a threadlike extension of a nerve cell and consists of an axon andmyelin sheath (if present) in the nervous system. There are nerve fibers in the central nervous system and peripheral nervous system. A nerve fiber may be myelinated and/or unmyelinated. In the central nervous system (CNS), myelin is produced byoligodendroglia cells. Schwann cells form myelin in the peripheral nervous system (PNS). Schwann cells can also make a thin covering for an axon which does not consist of myelin (in the PNS). A peripheral nerve fiber consists of an axon, myelin sheath, Schwann cells and its endoneurium. There are no endoneurium and Schwann cells in the central nervous system. A myocyte (also known as a muscle cell or muscle fiber) [1] is the type of cell found inmuscle tissue. They are long, tubular cells that arise developmentally from myoblasts to form muscles in a process known as myogenesis. [2] There are various specialized forms of myocytes: cardiac, skeletal, and smooth muscle cells, with various properties. Cardiac myocytes are responsible for generating the electrical impulses that control the heart rate, among other things
