Detailed explanation-1: -It is shown that dendrites have extensive connections with the axons in the form of axodendritic synapses, which form an important mode of communication between neurons (see Synapse below and Ch. 6, p. 110). They are the chief sensors of a neuron, in the sense that the dendrites receive the incoming signals first.
Detailed explanation-2: -Synapses: Dendrites receive signals from other neurons at specialized junctions called synapses. There is a small gap between two synapsed neurons, where neurotransmitters are released from one neuron to pass the signal to the next neuron.
Detailed explanation-3: -Dendrite – The receiving part of the neuron. Dendrites receive synaptic inputs from axons, with the sum total of dendritic inputs determining whether the neuron will fire an action potential.
Detailed explanation-4: -The dendrites serve to receive incoming electrical signals from other neurons. Most neurons have a single axon to transmit outgoing signals.
