The axon hillock is located at the end of the soma and controls the firing of the neuron. This results in the signal being transmitted down the axon. If the electrical impulses transmitted inward toward the cell body are large enough, they will generate an action potential. The neurons of the central nervous systems have very long and complex dendrites that then receive signals from as many as a thousand other neurons.
Some neurons have very small, short dendrites, while other cells possess very long ones. These dendrites then receive chemical signals from other neurons, which are then converted into electrical impulses that are transmitted toward the cell body. Most neurons possess these branch-like extensions that extend outward away from the cell body. Have many dendrites, or only one dendrite.
Dendrites are also covered with synapses.
These tiny protrusions receive information from other neurons and transmit electrical stimulation to the soma. BSIP/UIG / Universal Images Group / Getty Imagesĭendrites are tree-like extensions at the beginning of a neuron that help increase the surface area of the cell body.
