Which layer of the epidermis is known for its light touch sensitivity?

The layer of the epidermis associated with light touch sensitivity is indeed linked to Meissner's corpuscles. These specialized sensory receptors are located primarily in the dermal papillae, which are found just beneath the epidermis. Meissner's corpuscles are finely tuned to detect light touches and textures, making them crucial for the sensation of gentle pressures and vibrations on the skin. They are particularly abundant in areas such as the fingertips, palms, and soles of the feet, where sensitivity to touch is essential.

In contrast, other sensory receptors like Pacinian corpuscles are responsible for sensing deep pressure and vibration, Ruffini corpuscles detect skin stretch and sustained pressure, and Krause end bulbs are involved in the sensation of cold and perhaps other stimuli. However, their key functions do not primarily involve the detection of light touch, which is why the selection of Meissner's corpuscles is the most accurate answer to identify the layer of the epidermis known for its sensitivity to light touch.
