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. 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. 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. 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.
