Dendrites receive nervous system
signals through synapses, which form the connections between neurons
where the axon terminal of one nerve cell ends near the dendrites of
another nerve cell. Nerve cells do not physically touch each other.
Instead, they communicate through the use of neurotransmitters that
travel across the space called the synaptic cleft between the cells. An
electrical signal travels down one neuron's axon and triggers the
release of chemical compounds called neurotransmitters.
Neurotransmitters move across the synaptic cleft and connect to the
receptors on the other nerve cell. This triggers an electrical impulse
that then travels from the dendrites to the cell body.
The typical neuron has thousands of dendrites, but it is possible for
a nerve cell to have only one dendrite. Dendrites are relatively short,
and they have spines that provide more surface area for other neurons
to synapse with. Their branch-like formation inspired the name
"dendrite," which means "tree" in Greek.Hope This Helps :DSorry for such a long explanation.
