Detailed explanation-1: -When neurons communicate, an electrical impulse triggers the release of neurotransmitters from the axon into the synapse. The neurotransmitters cross the synapse and bind to special molecules on the other side, called receptors. Receptors are located on the dendrites. Receptors receive and process the message.
Detailed explanation-2: -At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter. The neurotransmitter can either help (excite) or hinder (inhibit) neuron B from firing its own action potential.
Detailed explanation-3: -Dendrites extend from the neuron cell body and receive messages from other neurons. Synapses are the contact points where one neuron communicates with another. The dendrites are covered with synapses formed by the ends of axons from other neurons.
