What is the nerve ending that detects touch, pressure, heat, cold, or pain?

• A. Hair Follicle
• B. Pore
• C. Dermis
• D. Nerve Ending

Answer: (D)

Nerve endings are the sensory receptors in the skin that detect touch, pressure, heat, cold, and pain. They are the ends of sensory neurons that translate physical or thermal stimuli into electrical signals sent to the brain. Some are free nerve endings that sense pain and temperature, while others are specialized structures like Meissner’s corpuscles for light touch, Merkel discs for steady pressure, and Pacinian corpuscles for deeper pressure and vibration. A hair follicle contains nerve fibers for detecting hair movement, but it isn’t the receptor for all these sensations. A pore is just an opening, and the dermis is the skin layer that houses many structures, not the nerve ending itself. So, the term nerve ending best identifies the receptors that detect these stimuli.
