Frequent question: What cells is the peripheral nervous system made of?

What cells are in the peripheral nervous system?

The two types of neuroglia found in the peripheral nervous system are satellite cells and Schwann cells. Neurons are the other the other type of cell that comprise nervous tissue.

What are the two types of cells in the PNS?

The PNS has two kinds of neuroglia: schwann cells and satellite cells. Schwann cells provide myelination to peripheral neurons. They also perform phagocytic functions and clear cellular debris, allowing for the regrowth of PNS neurons.

What are glia cells in the PNS?

The peripheral nervous system (PNS) consists of the nerves and ganglia outside of the brain and spinal cord. There are four major types of glia in the PNS. They are myelinating and non-myelinating Schwann cells, satellite glial cells (SGCs), enteric glial cells (EGCs), and olfactory ensheathing cells (OECs).

What cells produce myelin in the peripheral nervous system?

Schwann cells make myelin in the peripheral nervous system (PNS: nerves) and oligodendrocytes in the central nervous system (CNS: brain and spinal cord). In the PNS, one Schwann cell forms a single myelin sheath (Figure 1A).

What are the three main components of the peripheral nervous system?

The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve (cranial nerve II), along with the retina.

What makes up the peripheral nervous system quizlet?

The peripheral nervous system includes the cranial nerves (connected to brain innervate the head), spinal nerves (connected to spinal cord innervates the rest of the body), and ganglia (collections of neuron cell bodies in the PNS). … The spinal cord and its attached spinal nerves serve two important functions.

What is peripheral nervous system PDF?

What are Neuroglia cells?

Neuroglia are a large class of neural cells of ectodermal (astroglia, oligodendroglia, and peripheral glial cells) and mesodermal (microglia) origin. Neuroglial cells provide homeostatic support, protection, and defense to the nervous tissue.
