Parietal 

an anatomical term used with respect to animals to designate a close connection of an anatomical formation with the wall of a body cavity; contrasted with the term “visceral.” An example is the parietal layer of the peritoneum. In plants, the parietal ovules are those located along the walls of the ovary rather than in the center.
