use the diagram above to answer the next question.
which of the following actions will cause depolarization in this cell?
select one:
a. depolarization at the axon of a motor neuron
b. stimulation at a sensory receptor
c. depolarization at the dendrite of an interneuron
d. stimulation of an effector

Explanation:

The diagram shows a sensory neuron (with sensory receptors at the end). Sensory neurons are depolarized when their sensory receptors are stimulated (e.g., by a stimulus like touch, light, etc.), which initiates an action potential. Option a: Motor neuron axon depolarization wouldn't directly depolarize this sensory cell. Option c: Interneuron dendrite depolarization is unrelated to this sensory neuron. Option d: Stimulating an effector (like a muscle/gland) is the end of a motor pathway, not related to depolarizing this sensory cell. So stimulation at the sensory receptor (option b) causes depolarization here.

Answer:

b. stimulation at a sensory receptor
