What are the types of cutaneous receptors?

• A. Photoreceptors, chemoreceptors, mechanoreceptors, and thermoreceptors
• B. Free nerve endings, Merkel cells, Meissner’s corpuscles, Pacinian corpuscles, and Ruffini endings
• C. Neurons, glial cells, thermoreceptors, and nociceptors
• D. Color receptors, motion receptors, depth receptors, and taste receptors

Answer: (B)

The types of cutaneous receptors refer specifically to the sensory receptors located in the skin that are responsible for detecting various forms of stimuli. The correct answer identifies a variety of specialized receptors that play distinct roles in sensing touch, pressure, temperature, and pain. Free nerve endings are abundant in the skin and are responsible for sensing pain (nociception) and temperature changes. Merkel cells are involved in detecting fine touch and pressure. Meissner’s corpuscles are sensitive to light touch and are especially concentrated in areas of the skin that are sensitive to tactile stimuli, such as the fingertips. Pacinian corpuscles are designed to detect deep pressure and high-frequency vibration, while Ruffini endings respond to skin stretch and sustained pressure changes. These specific receptors allow the body to perceive and process a wide range of sensory information crucial for interaction with the environment. The other choices include receptor types that belong to different sensory modalities or do not specifically pertain to cutaneous sensations.
