Dendrites’ radius tapers, while axons’ remain constant. Most neurons have a lot of dendrites and only have one axon.ĥ. Generally, dendrites receive neuron signals, and axons transmit them.Ĥ. Dendrites are short and heavily branched in appearance, while axons are much longer.ģ. Dendrites receive electrochemical impulses from other neurons, and carry them inwards and towards the soma, while axons carry the impulses away from the soma.Ģ. Dendrites tube-like shape usually tapers, while the radius of axons remains constant.ġ. Other distinguishing physical characteristics of the axons and dendrites, besides the length and branching, are their shapes. However, these assertions are in a general sense, as there are some exceptions. The myelin coverings are insulators, and with their presence, axons are said to transmit more quickly.īasically, axons’ role is to transmit signals, and dendrites to receive such signals.

covered by a fatty substance identified as myelin). Larger axons are said to transmit information signals more quickly. Neural signals are transmitted through them after they have entered the soma of the neuron. Most nerve cells only have a single axon.Īxons extend from the soma to its terminal endings. Like dendrites, they are also protoplasmic projections of nerve cells, or neurons, and their primary purpose is to conduct electrochemical impulses away from the cell body of neurons. They are heavily branched in structure.Īxons are also called nerve fibers, as they appear elongated and slender. Most neurons have many of these protoplasmic protrusions, although they are rather short. They are situated at different points all over the dendritic arbor. Impulses are received by dendrites via synapses. So, what is the function of a dendrite As discussed above, the most basic function of dendrites is to establish functional contact with other cells in order to achieve a change in their behavior. The impulses they receive are carried inwards and towards the soma, or cell body. They are protoplasmic extensions of nerve cells, and operate as conductors of electrochemical stimuli received from neighboring cells. The support structures of the cell include mitochondria, which provide energy for the cell, and the Golgi apparatus, which packages products created by the cell and dispatches them to various locations. Nerve cells are the structural and functional units of the nervous system of animals. The soma produces the proteins that the other parts of the neuron, including the dendrites, axons, and synapses, need to function properly.

They are the axons and the dendrites.ĭendrites are branched projections of neurons its name comes from the Greek word ‘Dendron’, which means ‘Tree’, and is based on its evident tree-like appearance. Axon and dendrite are two components of nerve cells. There are two parts of nerve cells involved in the conduction of these nerve impulses. The nervous system is such an interesting and broad subject, and one of its disciplines is the understanding of nerve cells, or more simply called, neurons. These impulses are in the form of electrochemical signals that are passed from one nerve cell to the next, until they reach our brain for calculation and response. Have you ever wondered what sensations and perceptions involve? The sensations we feel are actually dictated by our brain, based on the impulses and stimulation it receives.
