The endocrine system is a control system of glands that secrete hormones that circulate within the body via the circulatory system to affect cells within certain organs of the body. The study of the endocrine system was known as endocrinology.
Doctor Christine Chapel pointed out the android Ilia's internal functions were patterned almost identically to the exocrine (and, therefore, endocrine) systems of her parent, Carbon-based lifeform. (Star Trek: The Motion Picture)
The novelization went on to explain the Illia probe also mimicked the release of Deltan pheromones.
One of Doctor Phlox's reasons for staying aboard Enterprise was that he was fascinated with the Human endocrine system, according to Captain Jonathan Archer. (ENT: "Broken Bow")
