Which set correctly lists the three main structural parts of a typical neuron?

• A. Node of Ranvier, Schwann cell, and neurilemma
• B. Dendrites, cell body (soma), and axon
• C. Axon terminals, myelin sheath, and synaptic cleft
• D. Nucleus, mitochondria, and ribosomes

Answer: (B)

Verified step by step guidance

1. Step 1: Understand that a typical neuron has three main structural parts that are essential for its function in transmitting nerve impulses.
2. Step 2: Identify the first main part: the dendrites, which receive incoming signals from other neurons or sensory receptors.
3. Step 3: Identify the second main part: the cell body (also called soma), which contains the nucleus and organelles responsible for maintaining the neuron's health and metabolism.
4. Step 4: Identify the third main part: the axon, a long projection that transmits electrical impulses away from the cell body toward other neurons or effector cells.
5. Step 5: Recognize that other options list components related to neurons but are either substructures (like myelin sheath) or organelles (like mitochondria), not the three main structural parts.
