With the passage of time, the degree of affinity that the dendrites of one neuron gain with the terminals of another causes a habitual communication path to be created, a fact that affects, even minimally, the progress of the mental operations that are going away conducting. It is these that regulate the chances that two nerve cells come into contact with more or less frequency, so they decide the “route” that the nerve impulses take. On the other hand, the potential of the brain to adapt to circumstances (for example, learning from experience) is also possible thanks to the work of dendrites. Thanks to this it is possible that the transmission of nerve impulses is established that allows the functioning not only of the brain, but of the entire nervous system, since there are neurons distributed throughout the body. In other words, the dendritic spines act as terminals to which the stimuli arrive from the other neuron that sends neurotransmitters through the synaptic space. The function of the dendrites in general, and of the dendritic spines in particular, is to act as the main contact of the neurotransmitters that arrive from outside. Since the time of the famous Spanish neurologist Santiago Ramón y Cajal, it has been known that neurons are relatively independent small bodies, that is, there is a separation between them.Ī part of this space that separates neurons from each other are the so-called synaptic spaces, which are the points through which these nerve cells pass information through substances called neurotransmitters. These are small formations called dendritic spines, which are, in turn, the places where the dendrites fulfill their main function, as we will see. In addition, there is still another class of microscopic processes on the surface of the dendrites. Compared to the axon, dendrites are usually shorter and thinner, so that they end closer to the cell body. Specifically, dendrites are small branches that come out of the cell body (the part of the neuron where the cell nucleus is located). Its main function is to receive impulses from other neurons and send them to the neuron’s soma.ĭendrites are parts of neurons that are found throughout the body, that is, both in the brain and spinal cord and in those that are in the ganglia, internal organs, muscles, etc. In this post we are going to answer the question ‘’What is the function of a dendrite?’’ we will discover what a dendrite is, how it is formed and what is its role within the brain. The dendrites, in turn, fulfill another function that we will see now. Neural axons, for example, with their elongated wire-like shape allow electricity to travel through them, regardless of whether or not they are accompanied by myelin sheaths. The different parts of neurons tell us a lot about how these tiny brain cells work.
