Neurotransmitters are chemicals that communicate between nerves. In some ways, neurons are like computers: they receive messages, process those messages, and send out the results as new messages to other cells. In the case of neurons, messages consist of chemicals that interact with the outer surface of the cell membrane. This chemical interaction with the […]

Considered to be an autoimmune disorder, MS attacks the myelin sheaths which surround and protect the nerve fibers. The affected myelin then forms scar tissue (hence the name), also referred to as plaques or lesions, which can damage the nerve fibers and disrupts the transmission of nerve impulses from the CONS (brain and spinal cord) […]

Popular Questions About Neuron

How do neurons work?
Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system. ... Neurons have three basic parts: a cell body and two extensions called an axon (5) and a dendrite (3).
What do neurotransmitters do?
Neurotransmitters are often referred to as the body's chemical messengers. They are the molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles. ... A neurotransmitter influences a neuron in one of three ways: excitatory, inhibitory or modulatory.Nov 9, 2017
Is neuron a cell?
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 are brain cells?
The brain is a mosaic made up of different cell types, each with their own unique properties. The most common brain cells are neurons and non-neuron cellsneuron cellsA nerve is an enclosed, cable-like bundle of fibers (called axons) in the peripheral nervous system. A nerve transmits electrical impulses. ... Nerve cells are called neurons. In the central nervous system, the analogous structures are known as nerve tracts.https://en.wikipedia.org › wiki › NerveNerve - Wikipedia called glia. ... Although neurons are the most famous brain cells, both neurons and glial cells are necessary for proper brain function.Aug 8, 2019
