Verified step by step guidance

Understand the function of each type of sensory cell listed in the options.

Ruffini endings are mechanoreceptors that respond to skin stretch and are involved in the perception of the position of the fingers and hand.

Merkel cells are mechanoreceptors that are sensitive to light touch and are found in the skin's epidermis, making them the correct answer.

Nociceptors are sensory receptors that respond to potentially damaging stimuli by sending signals to the spinal cord and brain, which is perceived as pain.

Pacinian corpuscles are mechanoreceptors that detect deep pressure and vibration, not light touch.
