In 1831, Italian anatomist Filippo Pacini discovered the corpuscle that carries his name, the Pacini corpuscle.Although the eponym is primarily used for this receptor, it is at times referred to as a lamellated sensory corpuscle, indicating the thick capsule that characterizes this nerve ending. 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.
