Which portion of a neuron primarily receives incoming information (signals) from other neurons?

• A. Myelin sheath
• B. Nodes of Ranvier
• C. Dendrites
• D. Axon terminal (synaptic knob)

Answer: (C)

Verified step by step guidance

1. Understand the basic structure of a 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 of the neuron that primarily receive incoming signals from other neurons.
3. Recognize that the myelin sheath and nodes of Ranvier are involved in speeding up the transmission of electrical impulses along the axon, not in receiving signals.
4. Know that the axon terminal (synaptic knob) is responsible for transmitting signals to the next neuron, not receiving them.
5. Conclude that the portion of the neuron that primarily receives incoming information from other neurons is the dendrites.
