A pea-sized gland at the base of the brain that controls other endocrine glands by producing various hormones. Often called the 'master gland,' it regulates growth, reproduction, metabolism, and stress responses.
From Latin 'pituita' meaning phlegm or mucus, named in the 17th century when anatomists mistakenly thought it produced nasal mucus. Despite the incorrect original assumption, the name stuck even after its true hormonal functions were discovered.
The pituitary is like the CEO of your endocrine system - it's tiny but tells all the other glands what to do! It's actually two glands in one: the front part makes its own hormones, while the back part stores and releases hormones made by the hypothalamus above it.
