In a typical neuron, which structure primarily receives incoming signals from other neurons?

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

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the basic structure of a typical neuron, which includes dendrites, the cell body (soma), the axon, myelin sheath, nodes of Ranvier, and axon terminals.
2. Step 2: Identify the function of dendrites, which are branched extensions of the neuron that primarily receive incoming signals (electrical or chemical) from other neurons.
3. Step 3: Recognize that the node of Ranvier is a gap in the myelin sheath along the axon that facilitates rapid signal conduction, but does not receive signals from other neurons.
4. Step 4: Understand that the axon terminal is the endpoint of the neuron where signals are transmitted to the next neuron or effector cell, rather than received.
5. Step 5: Know that the myelin sheath is a fatty layer that insulates the axon to speed up signal transmission, but it does not receive incoming signals.
