Synapse

Definition

noun, plural: synapses

A specialized structure or junction that allows cell to cell communication.

verb

(1) To form a synapse.

(2) To undergo synapsis.


Supplement

A biological synapse involving neurons can be:

(1) Chemical synapse : the junction between neurons such that the nerve impulse is transmitted from a neuron to another neuron or to a muscle cell or gland cell.

(2) Electrical synapse : the gap junction between two apposed neurons that allows faster nerve transmission.

Recently, a biological synapse not involving a neuron is found to exist. The junction between a lymphocyte and an antigen-presenting cell is referred to as immunological synapse.


Word origin: from "synaptein", which Sir Charles Scott Sherrington and colleagues coined from the Greek "syn-" ("together") and "haptein" ("to clasp").

Why do neurones only have one axon?

I think more than 1 would cause more issues than it would solve firstly the action potential can spread to multiple other neurones at a synapse and transmit signals very fast. I think what you actually want to know is would having multiple axons on a neurone speed up transmission of a nerve ...
