What is the primary function of Meissner's corpuscles?

Meissner's corpuscles are specialized sensory receptors located primarily in the upper dermis of the skin, particularly in areas that are sensitive to light touch, such as the fingertips, palms, and soles of the feet. Their primary function is to respond to tactile stimuli, specifically detecting light touch and providing the brain with information about texture and movement across the skin surface. These receptors are highly sensitive and adapt quickly, allowing for the perception of slight changes in pressure and touch.

While the skin contains other receptors that detect pressure, heat, or pain, Meissner's corpuscles specifically focus on light touch sensations, making them essential for tasks that require fine tactile discrimination. This distinction is critical for understanding how different sensory modalities are communicated to the brain, as each type of receptor is specialized for various functions within the tactile system.
