The Golgi Apparatus is made up of a number of flattened, membrane bound discs called Cisternae (singular Cisterna) [1]. The cisternae stack themselves upon each other to form Golgi stacks and their number can be anything in the range of 3-20 cisternae per stack [2]. The number of stacks per Golgi cell also vary between different cell types. 

These cisternae stacks have a cis side which is situated next to the endoplasmic reticulium (ER) and a trans side which faces the plasma membrane. Proteins packaged in the ER are transferred to the cis side on the Golgi stack via transport vesicles where they begin to travel towards the trans Golgi network to exit into the cytoplasm. From here, they will travel to either the cell surface or another organelle within the cell [3][4][5].
