Pituitary

L. pituita = mucous secretion. In the time of Galen the mucus from the nose and mouth was thought to come from the brain, hence this structure was so named. It has been suggested that the word “spit” comes from the same origin. It was a long time  before it was demonstrated that nasal mucus came from glands in the nose, and not though the cribriform plate of the ethmoid bone.
