Question

humans and animals are able to detect touch and monitor the position of their muscles due to _______

pain receptors
mechanoreceptors
chemoreceptors
photoreceptors

Explanation:

Identify the physiological function described

The question asks for the type of receptors responsible for detecting touch and monitoring muscle position (proprioception).

Analyze the receptor types

• Pain receptors (nociceptors) detect tissue damage or noxious stimuli.
• Mechanoreceptors respond to mechanical pressure, physical deformation, stretching, and vibration, which are responsible for both touch and muscle position sensing (via muscle spindles and Golgi tendon organs).
• Chemoreceptors detect chemical stimuli.
• Photoreceptors detect light.

Select the correct option

Mechanoreceptors are the specific sensory receptors that mediate touch and proprioception.

Answer:

• pain receptors
• mechanoreceptors (Correct answer)
• chemoreceptors
• photoreceptors
