In which situation will touch receptors be activated first?
Answer and explanation
Correct answer: When a thorn pricks
The governing concept is stimulus detection by specialised sensory receptors. A thorn prick directly stimulates receptors in the skin, including receptors associated with touch and pain. These receptors generate nerve impulses that travel through sensory nerves toward the central nervous system. Therefore option A is correct. Bright light activates photoreceptors in the eye, sweet taste activates taste receptors in the tongue, and a bell activates auditory receptors in the ear.
