Motor and associative neurons are able to receive information from many different sources simultaneously because of their profus
miskamm [114]

Motor and associative neurons can receive information from many different sources simultaneously because of their profusion of highly branched dendrites.

<h3>What are Dendrites?</h3>
  • Dendrons, which are also known as dendrites, are branched protoplasmic extensions of a nerve cell that transmit the electrochemical stimulation that the cell body, or soma, of the neuron from which the dendrites project, receives from other neural cells.
  • Through synapses, which are distributed throughout the dendritic tree, upstream neurons (often via their axons) transmit electrical stimulation onto dendrites.
  • Dendrites are essential for integrating these synaptic inputs and controlling how much an action potential is generated by a neuron.
  • A multi-step biological process called dendritic arborization often referred to as dendritic branching, is how neurons grow new dendritic trees and branches to produce new synapses.

To learn more about Dendrites, refer to:
