What part of the neuron receives incoming signals?

The part of the neuron that receives incoming signals is the dendrites. Dendrites are tree-like extensions of the neuron that branch out to form connections with other neurons and receive chemical signals from them. These signals typically come in the form of neurotransmitters released by other neurons at the synapse. Once the dendrites receive these signals, they convert them into electrical impulses that travel towards the cell body.

The axon, in contrast, is responsible for transmitting the electrical impulse away from the cell body and towards other neurons or muscles. The cell body contains the nucleus and is essential for the general functioning of the neuron, but it does not specifically engage in receiving incoming signals. The synapse is the junction between two neurons where neurotransmitters are released, rather than a part of the neuron itself that processes these signals.
