Question

gary (he/him) experienced damage to a sensory neuron in the peripheral nervous system. which neuron sustained damage?
second - order neuron
first - order neuron
third - order neuron
interneuron

Explanation:

First - order neurons are sensory neurons in the peripheral nervous system. They carry sensory information from sensory receptors to the central nervous system. Second - order neurons are in the central nervous system (e.g., spinal cord or brainstem) and receive input from first - order neurons. Third - order neurons are also in the central nervous system (usually in the thalamus) and receive input from second - order neurons. Interneurons are neurons that connect other neurons within the central nervous system. Since the damage is to a sensory neuron in the peripheral nervous system, it is a first - order neuron.

Answer:

First - order neuron
