Question

use the following information to answer question 25. the eye - blink reflex during a test for glaucoma at the optometrist, an eye blink occurs in response to a puff of air. 25. the structure labelled 1 represents part of a. a dendrite of a sensory neuron b. a dendrite of a motor neuron c. an axon of a motor neuron d. an axon of a sensory neuron

Explanation:

The eye - blink reflex is a simple reflex. The structure labeled 1 is part of the pathway that detects the stimulus (puff of air). Sensory neurons are responsible for detecting stimuli. Dendrites of sensory neurons receive the initial input. In the eye - blink reflex, the structure labeled 1 is a dendrite of a sensory neuron that detects the air puff.

Answer:

A. a dendrite of a sensory neuron
