An axon from greek ἄξων áxōn axis or nerve fiber is a long slender projection of a nerve cell or neuron in vertebrates that typically conducts electrical impulses known as action potentials away from the nerve cell body. 2016-02-03 For example, some have more elaborate dendritic branching while others differ in the placement of the cell body relative to other portions of the neuron. In addition to neurons, the nervous system is populated with another category of cells, glial cells. Glial cells are … bipolar (with one axon and one dendrite, found in the retina of eye) and unipolar (cell body with one axon only; found usually in the embryonic stage). There are two types of axons, namely, myelinated and non-myelinated.

Moreover, the actual lengths of axons and dendrites are close to the smallest most other cells of the body, neurons have long and branching processes: axons In other parts of the brain, these or some other functional constraints m Nerves are made up of cable-like bundles of nerve cells (neurons) and each neuron has three main parts, these are: 1. dendrites. 2. cell body. 3. axon. Find out about nerve cells and nerves and how nerve impulses travel around your called dendrites, and fibres that carry information away from it, called axons.

The myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon. The gaps between cell body = performs housekeeping functions of the cell . dendrite = receives chemical signals from other neurons and conduct electrical messages to cell body . axon = transmits electrical signals from cell body to axon terminal . axon terminal = converts electrical signal back to chemical signal by releasing transmitter substances (i) Dendrite (ii) Cell body (iii) Nucleus (iv) Axon (b) Name the parts of a neuron : (i) where information is acquired (ii) through which information travels as an electrical impulse (iii) where this impulse must be converted into a chemical signal for onward transmission (c) Define neuromuscular junction.

One axon extends centrally toward the spinal cord, the other axon extends toward the skin or muscle. Synapses are usually found between the fine terminal branches of the axon of one neuron and the dendrites or cell body of another. This type of neuron is called axo-dendrite synapse. Sir Charles Sherrington (1861-1954) was the first person who used the term ‘synapse’ to the junctional points between two neurons. The axon is the elongated fiber that extends from the cell body to the terminal endings and transmits the neural signal.

The function of the axon is to transmit information to different neurons, muscles and glands. In certain sensory neurons, such as those for touch and warmth, the electrical impulse travels along an axon from the cell to the cell body, and from the cell body to the spinal cord along another branch of the same axon.
