, and is now referred to as the ampulla of Vater.

In 1719, Vater was the first to notice oval-shaped organs of concentric layers of connective tissue wrapped around nerve endings in the skin. They were between 1–4 mm long, and he called these structures papillae nervae. Apparently his research was forgotten, because in 1831 they were rediscovered by anatomist Filippo Pacini

Filippo Pacini was an Italian anatomist, posthumously famous for isolating the cholera bacillus Vibrio cholerae in 1854, well before Robert Koch's more widely accepted discoveries thirty years later....

 (1812–1883) while performing a dissection of a hand. Pacini was the first to describe their functionality as mechanoreceptor
Mechanoreceptor
A mechanoreceptor is a sensory receptor that responds to mechanical pressure or distortion. There are four main types in the glabrous skin of humans: Pacinian corpuscles, Meissner's corpuscles, Merkel's discs, and Ruffini corpuscles...

s that are sensitive to vibration and pressure changes, and thus were to become known as Pacinian corpuscles. Today, the term "Vater-Pacini corpuscles" is sometimes used to credit the discoveries of both men. These organs are one of several types of mechanoreceptors in the body, some others being Meissner corpuscles
Meissner's corpuscle
Meissner's corpuscles are a type of mechanoreceptor. They are a type of nerve ending in the skin that is responsible for sensitivity to light touch. In particular, they have highest sensitivity when sensing vibrations lower than 50 Hertz...
