Which part of the neuron receives incoming signals?

Explanation:
Incoming signals from other neurons are detected by dendrites. These branched extensions are packed with receptors that bind neurotransmitters released across synapses, converting chemical signals into electrical changes on the dendritic membrane. The signals are then integrated in the soma and, if enough input is summed to reach threshold, an action potential is generated and travels along the axon. The axon’s role is to carry the signal away from the cell body, not to receive it, while the myelin sheath insulates and speeds conduction along the axon rather than participating in signal reception.
