Question 3

Which part of the neuron is responsible for transmitting nerve impulses *away* from the cell body towards other neurons or effector cells?

Accepted Answer

B. Axon — The axon is the elongated projection of a neuron that conducts electrical impulses away from the cell body (soma) to other cells.
