How do neurons communicate with other cells?
1 Answer
Good question.
Neurons communicate through neurohumor secretion.
Explanation:
Neurons possess cytoplasmic branches axon and dendrites, impulse communication is a one-way process. Axon will always deliver the message (dendrites are at receiving end).
Neurohumor substances are secreted only by axonic terminals. There are different chemicals which are released by neurons as neurohumor, such as acetylcholine, and epinephrine.
Neurosecretion by axonic terminal is followed by chemoreception. One neuron communicates with another by this process at synapse.
Neurons may secrete neurohumor substances directly in blood. This is true for hypothalamic neurons. The hormone reaches target organs with circulating blood stream.
Neurohumor may also be directly secreted in tissues, e.g. in muscles, or in glands.
There are specialised motor end plates formed by axonic terminals on muscle cells.
