What happens at the synapse between two neurons?
Synapse is a point of connection where two neurons get connected or communicated, where one neuron sends information to another target nerve cell. Synapses are electrical or chemical. Electrical is where flow or exchange if ions occurs and in chemical synapse, they communicate using chemical messengers called hormones, or neurotransmitters.
Sensory nerves carry nerve impulses in the form of electrical impulses to the axon terminal which releases chemical messengers called neurotransmitters, then they go through the synapse to reach the dendrite part of another neuron. And, finally these neurotransmitters go to muscles, glands etc. to carry forward their actions.
