Neurons Neurons are highly specialized nerve cells that generate and conduct nerve impulses. Its signaling device, or means of communicating with body cells, is electrical impulses, which are rapid and specific and cause almost immediate responses. These smaller cells surround and wrap or support and protect the delicate neurons. Collectively, these Schwann cells are called the Myelin Sheath. The nervous system is an organ system containing a network of specialized cells called neurons that coordinate the actions of an animal and transmit signals between different parts of its body. This strip is called the neural plate, and is the origin of the entire nervous system. The nervous system is responsible for the control of the body and the communication among its parts. carry information from the senses to the CNS and from the CNS to the skeletal muscles. These cells that form myelin, protect, support, and maintain equilibrium in your nervous system are called glial cells. c ) Supporting Cells in the CNS The supporting cells of the CNS are collectively called neuroglia or simply, glial cells Like neurons, glial cells have branching processes and a central cell body Neuroglia can be distinguished by their much smaller size and by their darker staining nuclei They outnumber neurons in the CNS by a .

Neuron, serving as part of the conduction pathway between sensory and motor neurons. The peripheral nervous system consists of satellite cells (provide physical support and create a protective layer around the cell and also give the cell the nutrients they need) and Schwann cells (synthesize myelin around the axon of the neuron). Axon. As the cell body re-grows the axon, it uses the path that is marked by the glia cells. This group of cells includes, on the one hand . The PNS does this with specialized nerve cells called afferent and efferent neurons. A glial cell similar to an astrocyte but with fewer protuberances, concerned with the production of myelin in the central nervous system. . In the peripheral nervous system, nerve cells are located in ganglia, which are simply local accumulations of nerve cell bodies (and supporting cells).Peripheral axons are gathered into nerves, which are bundles of axons, many of which are enveloped by the glial cells of the peripheral nervous system, the Schwann cells.In the central nervous system, nerve cells are arranged in two different .
