Which structures are responsible for recognizing touch, temperature, sight, hearing, taste, smell, pain, and pressure?

• A. Sensory nerves
• B. Motor nerves
• C. Mixed nerves
• D. Efferent nerves

Answer: (A)

Sensory nerves are the structures that recognize and relay information about touch, temperature, sight, hearing, taste, smell, pain, and pressure. They carry afferent signals from specialized receptors in the skin, eyes, ears, tongue, and nose to the brain, where the signals are interpreted. The receptors include mechanoreceptors for touch and pressure, thermoreceptors for temperature, nociceptors for pain, photoreceptors in the retina for sight, hair cells in the inner ear for hearing, and gustatory and olfactory receptors for taste and smell. Motor nerves, by contrast, carry signals from the brain to muscles or glands, not sensory information. Mixed nerves contain both sensory and motor fibers, but the sensing part comes from the sensory components.
