Which part of the neuron conducts impulses away from the nerve cell body?

• A. Dendrite
• B. Axon
• C. Soma (cell body)
• D. Synaptic cleft

Answer: (B)

Verified step by step guidance

1. Understand the structure of a neuron: A neuron consists of three main parts - the dendrites, the soma (cell body), and the axon. Each part has a specific function in transmitting nerve impulses.
2. Learn the role of dendrites: Dendrites are extensions of the neuron that receive signals from other neurons and conduct impulses toward the soma (cell body). They are not responsible for conducting impulses away from the cell body.
3. Understand the function of the soma (cell body): The soma contains the nucleus and other organelles. It integrates incoming signals from the dendrites but does not conduct impulses away from itself.
4. Examine the role of the axon: The axon is a long, slender projection of the neuron that conducts electrical impulses away from the soma (cell body) toward other neurons, muscles, or glands. This is the part responsible for transmitting signals away from the nerve cell body.
5. Clarify the synaptic cleft: The synaptic cleft is the gap between the axon terminal of one neuron and the dendrites or soma of another neuron. It is involved in the transmission of signals between neurons but does not conduct impulses away from the cell body itself.
