what are the two types of cells found in the nervous system?

There are two broad classes of cells in the nervous system: neurons, which process information, and glia, which provide the neurons with mechanical and metabolic support. Three general categories of neurons are commonly recognized (Peters, Palay, & Webster, 1976).

Peripheral Nervous System. The peripheral nervous system is divided into two major parts: the somatic nervous system and the autonomic nervous system.

The nervous system comprises of two group of cells, glial cells and neurons.

The four types of neuroglia found in the central nervous system are astrocytes, microglial cells, ependymal cells, and oligodendrocytes. 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.

Neurons. Neurons, or nerve cell, are the main structural and functional units of the nervous system. Every neuron consists of a body (soma) and a number of processes (neurites). The nerve cell body contains the cellular organelles and is where neural impulses (action potentials) are generated.

The autonomic nervous system consists of 2 main divisions, the sympathetic and the parasympathetic nervous systems.

The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon. The main part of the cell, the part that carries on the general functions, is the cell body.

The functions of the nervous system are performed by two types of cells: neurons, which transmit signals between them and from one part of the body to another, and glia, which regulate homeostasis, providing support and protection to the function of neurons.

Astrocytes, Oligodendrocytes, and Schwann Cells. Central nervous system (CNS) is composed of two major cell types: neuron and glia. ... Consistently, the CNS houses oligodendrocytes for myelin synthesis. On the other hand, Schwann cells are the myelinating cells in the peripheral nervous system (PNS).

In the human body, nervous system cells are haploid or diploid.

The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. The nervous system includes both the Central nervous system and Peripheral nervous system.

Nervous tissue contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses. Neuroglia are supporting cells that provide physical sport, remove debris, and provide electrical insulation.

Nervous tissue is grouped into two main categories: neurons and neuroglia. Neurons, or nerves, transmit electrical impulses, while neuroglia do not; neuroglia have many other functions including supporting and protecting neurons.

system. there are two major divisions of the nervous system the first is the central nervous system. which is made up of the brain and the spinal cord. the second is the peripheral nervous system which consists of nerves that run throughout the body the peripheral nervous system itself is made up of two subdivisions.

Types of Neurons (Nerve Cells) The human body is made up of trillions of cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry "messages" through an electrochemical process. The human brain has approximately 86 billion neurons.
