Lamellar corpuscles, or Pacinian corpuscles, are one of the four major types of mechanoreceptor.They are nerve endings in the skin responsible for sensitivity to vibration and pressure. Because of their superficial location in the dermis, these corpuscles are particularly sensitive to touch and vibrations, but for the same reasons, they are limited in their detection because they can only signal that something is touching the skin. Side view of a papilla of the hand. Meissner’s corpuscles (tactile corpuscles) Meissner’s corpuscles are found in the dermal papillae of hairless skin. They respond only to sudden disturbances and are especially sensitive to vibration. [11], If the stimulus is removed, the corpuscle regains its shape and while doing so (i.e. Microsc Res Tech.

Pacinian corpuscles are mechanoreceptors found in man and other animals. The four major types of tactile mechanoreceptors include: Merkel’s disks, Meissner’s corpuscles, Ruffini endings, and Pacinian corpuscles. Meissners corpuscles These are highly sensitive mechanoreceptors for touch found on the palmar surface of fingers and plantar service of feet (highly tactile). Feelings of deep pressure (from a poke, for instance) are generated from lamellar corpuscles (the only other type of phasic tactile mechanoreceptor), which are located deeper in the dermis, and some free nerve endings. These tasks are left to other types of nerve endings. What is their function? In particular, they have highest sensitivity (lowest threshold) when sensing vibrations between 10 and 50 Hertz.
