Dendrites are the parts of the neuron specifically designed to receive signals from other neurons. They extend from the soma (cell body) of the neuron and are equipped with receptors that bind neurotransmitters released from adjacent neurons at the synapse. When these receptors are activated, they initiate a response in the receiving neuron, which can lead to the generation of an action potential if the stimulus is strong enough.

The axon primarily functions to transmit electrical impulses away from the cell body to other neurons or muscles. The soma contains the nucleus and organelles essential for the neuron's metabolic processes but is not directly involved in signal reception. The synapse is the junction between two neurons where communication occurs but is not a structure of a single neuron. Therefore, dendrites are uniquely suited to collect and integrate the inputs necessary for neuronal signaling.
