What is the function of oligodendrocytes and Schwann cells?


What is the function of oligodendrocytes and Schwann cells?

Oligodendrocytes and Schwann cells are engaged in myelin production, maintenance and repairing respectively in the central nervous system (CNS) and the peripheral nervous system (PNS).

What are the characteristics of oligodendrocytes?

Oligodendrocytes have small amounts of cytoplasm surrounding rounded nuclei, and possess only a few short processes. There are two main types: satellites around neurons in the gray matter. myelin-forming cells in the white matter.

Which type of cell has a single process that functions as an axon and dendrite most sensory neurons fit into this classification?

Unipolar neurons have a single short process that emerges from the cell body and divides T-like into proximal and distal branches. Bipolar neurons have two processes, an axon and a dendrite, that extend from opposite ends of the soma. Multipolar neurons, the most common type, have one axon and two or more dendrites.

What is the function of dendrites Class 10?

When nerve impulse reaches the muscle cells move by changing their shape. Special proteins cause both change in shape and their arrangement in the cell in response to nervous electrical impulses. Draw the structure of a neuron and explain its function.

How the structure of the oligodendrocytes relate to their function?

The primary function of oligodendrocytes is to make myelin sheath around the axons in the white matter of CNS. They do this by wrapping around the axons and forming layers of the membrane around them. The cytoplasm condenses and the membrane layers fuse to form the myelin sheath.

What are the functions of the dendrites cell body and axon of a neuron?

Most neurons have a cell body, an axon, and dendrites. The cell body contains the nucleus and cytoplasm. The axon extends from the cell body and often gives rise to many smaller branches before ending at nerve terminals. Dendrites extend from the neuron cell body and receive messages from other neurons.

What is purpose do oligodendrocytes serve?

Oligodendrocytes (from Greek, meaning ‘cells with a few branches’), or oligodendroglia, are a type of neuroglia whose main functions are to provide support and insulation to axons in the central nervous system of some vertebrates, equivalent to the function performed by Schwann cells in the peripheral nervous system.

What do oligodendrocytes and Schwann cells produce?

Similarities Between Schwann Cell and Oligodendrocyte Schwann cells and oligodendrocytes are two types of glial cells found in the nervous system of higher vertebrates. The main function of both Schwann cells and oligodendrocytes is to insulate the axons of the nerve cells. Both Schwann cells and oligodendrocytes are capable of forming myelin sheaths around the axons.

What is the function of oligodendrites?

Oligodendrocyte, a type of neuroglia found in the central nervous system of invertebrates and vertebrates that functions to produce myelin, an insulating sheath on the axons of nerve fibres.

What is the function of oligondendrocytes?

Oligodendrocytes , also known as oligodendroglia, are a type of brain cell in the central nervous system that belongs to the glial cell family. The main purpose of glial cells is maintenance and support of nervous system cells. Oligodendrocytes support neurons by producing a substance called myelin ,…
