In a single neuron, an impulse normally travels in the direction
Correct answer: C. dendrite to cell body to axon
- A. axon to dendrite to cell body
- B. cell body to dendrite to axon
- C. dendrite to cell body to axon
- D. axon to cell body to dendrite
Explanation
Dendrites receive signals and conduct them to the cell body, and the axon carries the impulse away to the terminals. The synapse then enforces the same one way flow onto the next cell.

About Receptors
Receptors are specialized cells or proteins that detect stimuli such as light, sound, pressure, temperature and chemicals, then initiate responses through sensory or hormonal pathways. Questions distinguish sensory receptors from effectors, compare receptor types, and examine stimulus conversion into nerve impulses, including the roles of rods, cones, chemoreceptors and mechanoreceptors.
