Definition: The antehypophysis, also known as the pituitary gland, is a small, circular organ located in the anterior part of the brain called the hypothalamus. It produces hormones that influence body functions, such as thirst, hunger, sleep cycles, and sex drive. The definition of the "antehypophysis" is not clearly defined in the Bible but typically refers to the gland which secretes hormones into the pituitary (pituitary gland) which regulates other glands. It's important to note that the exact term used in the Bible might differ based on context.
