Which neuron structure tends to be long and slender and conducts impulses away from the cell body?

Which neuron structure tends to be long and slender and conducts impulses away from the cell body?

• A. Dendrite
• B. Axon
• C. Cell body
• D. Neuroglia

Answer: (B)

Neurons have two main types of projections: dendrites and axons. Dendrites are usually short and branched, and they receive signals from other neurons. The axon is typically long and slender and carries electrical impulses away from the cell body toward other neurons or muscles. This direction—away from the cell body—and the elongated shape are defining features of the axon. The cell body contains the nucleus and organelles, while neuroglia are supportive cells. So the structure described as long and slender and conducting impulses away from the cell body is the axon.
