How Senses Detect Stimuli Practice Test

A simplified model shows bright light (stimulus) shining from a lamp in the environment onto the light receptors in the eye. The model shows a line from the lamp to the receptors and a label “signal begins in receptor.” The person then squints (response). Which explanation shows how the stimulus is detected based on the model?

Remember: receptors detect stimuli, and detection is not the same as the response.

A simplified model shows sharp pin (stimulus) pressing into the skin and contacting pain receptors near the surface. The model shows a cue “signal starts” at the receptor at the point of contact. The person then pulls their hand back (response). Which statement about detection is supported by evidence in the model?

Remember: receptors detect stimuli, and detection is not the same as the response.
