Which neuron part primarily receives incoming signals from other neurons?

Which neuron part primarily receives incoming signals from other neurons?

• A. Axon
• B. Dendrite
• C. Myelin sheath
• D. Nucleus

Answer: (B)

The main idea is where neurons receive signals from other neurons. Dendrites are the branch-like parts that have receptors for neurotransmitters released by neighboring neurons at synapses. They collect these chemical messages and pass the information toward the cell body for integration. The axon, in contrast, is the long projection that carries signals away to other neurons or muscles. The myelin sheath speeds up that transmission along the axon, and the nucleus houses the cell’s genetic material and helps control cellular functions. Because receiving incoming signals happens at the dendrites, they’re the primary site for signal reception.
