Answers:
A septum (Latin: something that encloses; plural Septa) is a partition separating two cavities or spaces. Examples include:
Nasal Septum: cartilage dividing nostrils of the human nose. Often deviated or perforated through physical injury or cocaine abuse.
Cephalopod Septa: walls between each chamber, or siphuncle, in shells of nautiloids, ammonites, and belemnites; i.e. cephalopods that retain an external shell.
