In a typical neuron, which structure primarily receives incoming information (synaptic input) from other neurons?

• A. Myelin sheath
• B. Node of Ranvier
• C. Axon terminals
• D. Dendrites

Answer: (D)

Verified step by step guidance

1. Understand the basic structure of a typical neuron, which includes dendrites, a cell body (soma), an axon, myelin sheath, nodes of Ranvier, and axon terminals.
2. Recall the function of dendrites: they are branched extensions from the neuron's cell body that primarily receive incoming signals or synaptic inputs from other neurons.
3. Recognize that the myelin sheath is a fatty layer that insulates the axon to speed up electrical signal transmission, but it does not receive signals.
4. Know that nodes of Ranvier are gaps in the myelin sheath that facilitate rapid conduction of nerve impulses along the axon, not reception of signals.
5. Identify that axon terminals are the endings of the axon that transmit signals to other neurons or effector cells, rather than receiving signals.
