What is the primary site on a neuron for receiving signals from other neurons?

Dendrites

Explanation:

Dendrites or dendrons are the branching of protoplasmic extensions of a nerve cell. As the neurons are arranged in head to tail manner, these dendrites lie close to the axon terminals of the other neuron and thus they receive signals from the other neurons and then pass the received signal to the main body of the neuron which is also called Soma. The electrical signals are passed from one neuron to the other neurons via the synapses which are located at various points on the dendrites.
