Golgi's apparatus

Related people

A so-called internal network which is a lamellar membranous structure near the nucleus of almost all cells. A system of membranes in the cytoplasm of the cell making up a functional unit concerned with intracellular transport of membrane-bounded secretory proteins. It contains curved parallel series of flattened saccules that are often expanded at their ends. The structure is best seen by electron microscopy. Basically it is a cell's 'packaging plant.' In secretory cells the apparatus functions to concentrate and package the secretory product. Its function in other cells, though apparently important, is poorly understood.

This was first described in 1867 in the sexual cells of snails by Adolf Freiherr Von La Valette St. George (1831-1910).
