What links the neuron to other neurons?

• A. Dendrites
• B. Axon
• C. Cell body
• D. Myelin sheath

Answer: (A)

The part that connects a neuron to others is the dendrites. Dendrites receive signals from the axon terminals of other neurons at synapses, using neurotransmitter receptors on their surface. This input is then integrated in the cell body and, if strong enough, triggers an electrical impulse that travels down the axon to communicate with the next neuron. The axon carries signals away from the neuron, the cell body processes incoming information, and the myelin sheath speeds up conduction along the axon but doesn’t form the direct link between neurons.
