What are found in the central nervous system?

What are found in the central nervous system?

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 is the name of clusters of cell bodies that are located outside the central nervous system?

The cell bodies of other PNS neurons, such as the sensory neurons that provide information about touch, position, pain, and temperature, are located outside of the CNS, where they are found in clusters known as ganglia. The axons of peripheral neurons that travel a common route are bundled together to form nerves.

What are the supporting cells in the central nervous system called?

Nervous tissue is composed of neurons and supporting cells called neuroglia, or ” glial cells.”

What are nuclei in the central nervous system?

In neuroanatomy, a nucleus (plural form: nuclei) is a cluster of neurons in the central nervous system, located deep within the cerebral hemispheres and brainstem. A nucleus may itself have a complex internal structure, with multiple types of neurons arranged in clumps (subnuclei) or layers.

What are the 7 main parts of the central nervous system?

The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).

What is the main supporting tissue of the central nervous system?

neuroglia
Nervous tissue is one of four major classes of tissues. It is specialized tissue found in the central nervous system and the peripheral nervous system. It consists of neurons and supporting cells called neuroglia.

What are the two types of nervous system cells?

Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.

What are the clusters of cells called in the nervous system?

Clusters of cell bodies in the central nervous system are called nuclei, while the cell bodies lining the nerves in the peripheral nervous system are called ganglia.

Which is a major component of the central nervous system?

Key Takeaways. Key Points. Gray matter is a major component of the central nervous system, consisting of neuronal cell bodies and other cells such as glia and dendrites. The white matter is composed of bundles of myelinated axons (few cell bodies) that connect various grey matter regions.

What makes up the gray matter of the central nervous system?

The central nervous system consists of a central cavity surrounded by gray matter made of neuronal cell bodies and white matter made of myelinated axons. Gray matter is a major component of the central nervous system, consisting of neuronal cell bodies and other cells such as glia and dendrites.

What is the bundle of axons called in the central nervous system?

In the peripheral nervous system a bundle of axons is called a nerve. In the central nervous system a bundle of axons is called a tract. Each axon is surrounded by a delicate endoneurium layer.
