The study was published in a 101-paged article in The Journal of Hygiene in 1908; where Haldane was described as "Jack Haldane (age 13)" for whom it "was the first time [he] had ever dived in a diving dress". [28]: 436 The research became a foundation for a scientific theory called Haldane's decompression model. [29]
The cell was first discovered by Robert Hooke in 1665 using a microscope. The first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830s. In this theory the internal contents of cells were called protoplasm and described as a jelly-like
The cell is the unit of structure, physiology, and organization in living things. [32] The cell retains a dual existence as a distinct entity and a building block in the construction of organisms. [32] By the 1860s, these tenets were the accepted basis of cell theory, used to describe the elementary anatomical composition of plants and animals. [3]
Illustration of Virchow's cell theory. Virchow is credited with several key discoveries. His most widely known scientific contribution is his cell theory, which built on the work of Theodor Schwann. He was one of the first to accept the work of Robert Remak, who showed that the origin of cells was the division of pre-existing cells. [29]
Andries van Wezel (31 December 1514 – 15 October 1564), latinized as Andreas Vesalius (/ v ɪ ˈ s eɪ l i ə s /), [2] [a] was an anatomist and physician who wrote De Humani Corporis Fabrica Libri Septem (On the fabric of the human body in seven books), which is considered one of the most influential books on human anatomy and a major advance over the long-dominant work of Galen.
The appendix has been identified as an important component of mammalian mucosal immune function, particularly B cell-mediated immune responses and extrathymically derived T cells. This structure helps in the proper movement and removal of waste matter in the digestive system, contains lymphatic vessels that regulate pathogens, and lastly, might ...
Much of the nomenclature, methods, and applications for the study of anatomy can be traced back to the works of the ancient Greeks. [3] In the fifth-century BCE, the philosopher Alcmaeon may have been one of the first to have dissected animals for anatomical purposes, and possibly identified the optic nerves and Eustachian tubes. [4]
He discovered the loop of Henle and Henle's tubules, two anatomical structures in the kidney. [5] Other anatomical and pathological findings associated with his name are: [5] Crypts of Henle: microscopic pockets located in the conjunctiva of the eye. Hassall–Henle bodies: transparent growths in the periphery of the Descemet's membrane of the eye.
