Similar in physiology to the Meissner's corpuscle, Lamellar corpuscles are larger and fewer in number than both Merkel cells and Meissner's corpuscles. The entire corpuscle is wrapped by a layer of connective tissue. A Pacinian corpuscle is an onion-shaped structure of nonneural (connective) tissue built up around the nerve ending that reduces the mechanical sensitivity of the nerve terminal itself.

Pacinian neuroma arises from the Pacinian corpuscles, a specialized type of nerve that is responsible for deep touch and vibration sensation The condition is thought to be an abnormal response to trauma/injury, causing the Pacinian corpuscles to become large, resulting in the formation of a benign tumor or neuroma An example of a Meissner's corpuscle. The key difference between Meissner’s corpuscles and Pacinian corpuscles is that Meissner’s corpuscles are encapsulated receptors that respond to low-frequency vibrations and fine touch while Pacinian corpuscles are deep receptors that respond to deep pressure and high-frequency vibration.. Mechanoreceptors are a type of sensory receptors that are able to sense … Meissner is smooth to pronounce – found on smooth skin and detects smooth (fine) touch.
