Henry Jones Shrapnell tympanic membrane is known as "Shrapnell's membrane". During the same year, Shrapnell published two other articles in the same journal, these being in regards to the function of the tympanic membrane and the nerves of the ear. In 1833, he published an article (again in the same journal) on the anatomy of the incus. Henry Jones Shrapnell Henry Jones Shrapnell (1792–1834) was an English anatomist. For a period of time during his career he was a colleague to Edward Jenner (1749-1823), creator of the vaccine for smallpox. Shrapnell is remembered for his pioneer work in otology. He was the first
Basilar membrane membrane is also the "base" for the sensory cells of hearing, the hair cells that are equipped with "Stereocilia". There are approximately 15,000 hair cells in each human ear (see figure). This function as base of the sensory cells gave the "basilar" membrane its name, and it is again present in all land vertebrates. Due to its location, the basilar membrane places the hair cells in a position where they are adjacent to both the endolymph and the perilymph, which is a precondition of hair cell function. A third, evolutionarily younger, function of the basilar membrane is strongly developed in
