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
Plasma membrane Ca2+ ATPase to involve the lymph nodes, and are more common among young women, which could help explain their worse prognosis compared with postmenopausal women. PMCAs were first discovered in the 1960s in the membranes of red blood cells. The presence of an ATPase was discovered in the membranes in 1961, and then in 1966 it was discovered that these ATPases pump Ca out of the cytosol. PMCA was first purified from red blood cell membranes in 1979. Plasma membrane Ca2+ ATPase The plasma membrane Ca ATPase (PMCA) is a transport protein in the plasma membrane of cells and functions to remove
