What type of sensory input do Merkel's corpuscles respond to?

Merkel's corpuscles are specialized mechanoreceptors located in the skin, particularly in areas that are sensitive to light touch, such as the fingertips and lips. They play a crucial role in detecting fine tactile stimuli, allowing us to perceive texture and shape. The correct response pertains specifically to their sensitivity to light touch, rather than deep pressure, which is more associated with other types of mechanoreceptors, such as Pacinian corpuscles. While Merkel's corpuscles do contribute to the perception of pressure, their primary function is to provide detailed sensory information about light touch, making them essential for tasks that require fine motor skills and tactile discrimination.
