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.
What is the cell of the nervous system?
The nervous system comprises of two group of cells, glial cells and neurons. Neurons are responsible for sensing change and communicating with other neurons. Glial cells work to support, nourish, insulate neurons and remove waste products. This article will discuss the function of neurons and glial cells.
What are the cells of the central nervous system?
The central nervous system (CNS) is now thought to consist of three main cell types: neurons, glial cells and vascular cells.
What are the four types of cells in the nervous system?
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.
What is the basic nerve cell of the nervous system called?
The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, which includes the nucleus, a major branching fiber (axon) and numerous smaller branching fibers (dendrites).
What two cells make up the nervous system?
Cells of 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.
What is the most important cell in the nervous system?
Neurons are the central building blocks of the nervous system, 100 billion strong at birth. Like all cells, neurons consist of several different parts, each serving a specialized function ([link]).
What are the four major components of the central nervous system?
- 2.1 White and gray matter.
- 2.2 Spinal cord. 2.2.1 Cranial nerves.
- 2.3 Brain. 2.3.1 Brainstem. 2.3.2 Cerebellum. 2.3.3 Diencephalon. 2.3.4 Cerebrum.
- 2.4 Difference from the peripheral nervous system.
What are the 3 types of nervous system?
There are three types of nerves in your body: autonomic nerves, motor nerves, and sensory nerves. SOURCES: National Institute of Neurological Disorders and Stroke: “NINDS Peripheral Neuropathy Information Page.” Neuropathy Association: “About Peripheral Neuropathy: Facts.”
What are the main parts of central nervous system?
The nervous system has two main parts:
- The central nervous system is made up of the brain and spinal cord.
- The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

What are the two major subdivisions of the nervous system?
The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
What organs are in the nervous system?
The nervous system in a human is made of the brain, spinal cord, sensory organs and all the neurons that serve as communication channels between the various organs of the body.
Where is nervous tissue found in the body?
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.
What is the purpose of nerve cell?
Neurons, also known as nerve cells, send and receive signals from your brain. While neurons have a lot in common with other types of cells, they’re structurally and functionally unique. Specialized projections called axons allow neurons to transmit electrical and chemical signals to other cells.
What is the main function of the peripheral nervous system?
The PNS has three basic functions: (1) conveying motor commands to all voluntary striated muscles in the body; (2) carrying sensory information about the external world and the body to the brain and spinal cord (except visual information: the optic nerves, which convey information from the retina to the brain, are in …
What are the types of nerve cell?
For the spinal cord though, we can say that there are three types of neurons: sensory, motor, and interneurons.
- Sensory neurons. …
- Motor neurons. …
- Interneurons. …
- Neurons in the brain.
