Answer:

1. merkel cells

2. tactile corpuscle

3. lamellated (lamellar) corpuscle

4. nociceptors

Explanation:

Merkel cells are epithelial cells found around hair follicles which are capable of sensing gentle touch sensations such as, for example, tactile discrimination and environmental exploration. Tactile corpuscles are a class of nerve ending required for mediating sensitivity to light touch sensations. The lamellar corpuscles are another class of nerve ending capable of sensing deep touch sensations and vibrations. Finally, nociceptors are somatic sensory receptors capable of sensing noxious (damaging) stimuli.
