Question

WHAT IS A SYNAPSE? DESCRIBE TRANSMISSION OF NERVE IMPULSE AT THE SYNAPSE

Answer 1

Synapse is a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.

Answer 2

Explanation:

At a synapse, one neuron sends a message to a target neuron—another cell. ... At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters. These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential.
