Merkel Cells are described as sensing:

• A. Pressure and vibrations
• B. Light touch
• C. Heat
• D. Cold

Answer: (A)

Merkel cells are slow-adapting mechanoreceptors in the basal layer of the epidermis that provide high-resolution touch information. They respond to sustained pressure and to texture and shape details, helping you discern fine features by touch. Heat and cold are detected by thermoreceptors, not Merkel cells, and vibration is primarily sensed by other mechanoreceptors such as Pacinian corpuscles. Among the options, the sense that best fits Merkel cell function is light touch, since these cells specialize in detailed, steady tactile perception rather than temperature or vibration.
