Which part of the neuron receives signals from other neurons?

The dendrite is the part of the neuron that receives signals from other neurons. Dendrites are tree-like extensions from the neuron's cell body and are equipped with receptors that detect neurotransmitters released by neighboring neurons at synapses. When these neurotransmitters bind to receptors on the dendrites, they generate graded potentials, which can lead to the generation of action potentials if the signal is strong enough.

The axon, on the other hand, is responsible for transmitting electrical impulses away from the cell body toward other neurons or muscles. The cell body contains the nucleus and is essential for integrating inputs received from the dendrites, but it does not directly receive signals itself. The synapse is the junction between two neurons where this signaling occurs, but it is not a part of the neuron that receives signals; rather, it is the site of communication between neurons through the release and reception of neurotransmitters. Thus, dendrites play a crucial role in the reception of incoming signals, making them the correct choice in this context.
