what is a synapse in biology

Synapse is the junction between two neurons. Neurons have an expanded part called Cyton. This contains the nucleus and thin projections called dendrites. It is these dendrites that receive the signal. From cyton appears a slender long branch caled axon. At the junction of cyton and axon, the message (changes in the cyton) transforms into biochemical changes across the axon membrane, creating a voltage change. This voltage change is the signal that transcends across the axon to reach the find branches from axon, called the nerve endings. Here, these nerve endings and the dendrites of the next neuron create a junction, which we call the synapse. This synapse is where the nerve endings release neurotransmitters, chemicals, that communicate biochemical changes to the cyton of the next neuron.

FAQ

What is a synapse simple definition?

A synapse is a junction between two neurons formed by a neuron’s nerve endings and dendrites of the next neuron. This is where the signal passes between two neurons by using chemical neurotransmitters or ionic contacts.
