Which structures detect touch and temperature?

• A. Dermal Papillae
• B. Nerve Endings
• C. Capillaries
• D. Macrophages

Answer: (B)

Touch and temperature are detected by sensory nerve endings in the skin. These nerve endings respond to mechanical stimulation and temperature changes, generating nerve impulses that are sent to the brain for perception. Dermal papillae are dermal projections that help nourish the epidermis and influence grip but aren’t receptors themselves. Capillaries supply blood, and macrophages are immune cells. So the structures responsible for detecting touch and temperature are the nerve endings.
