Answer 2

Answer:

A synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Synapses are found where nerve cells connect with other nerve cells.An electrical impulse travels down the axon of a neuron and then triggers the release of tiny vesicles containing neurotransmitters. These vesicles will then bind to the membrane of the presynaptic cell, releasing the neurotransmitters into the synapse. These chemical messengers cross the synaptic cleft and connect with receptor sites in the next nerve cell, triggering an electrical impulse known as an action potential. These neurotransmitters contain the information which has to be delivered to the effector cells.
