Question

use the following information to answer question 26. in which diagram do the arrows show the direction of a nerve impulse generated in the normal fashion? 26. in which diagram above do the arrows show the direction of a nerve impulse in the normal fashion? a. diagram a b. diagram b c. diagram c d. diagram d

Explanation:

Nerve impulses travel from the receptor to the central - nervous system (CNS) via sensory neurons, and then from the CNS to the effector via motor neurons. In a normal reflex arc, the cell body of the sensory neuron is in the ganglion. The impulse direction should be from the receptor to the CNS and then from the CNS to the effector. Diagram D shows the correct direction of nerve impulses where the impulse moves from the receptor to the CNS and then from the CNS to the effector.

Answer:

D. Diagram D
