Pituitary gland protective bony enclosure called the sella turcica. It is composed of three lobes: anterior, intermediate, and posterior. In many animals, these three lobes are distinct.The intermediate is avascular and almost absent in human beings. The intermediate lobe is present in many lower animal species, in particular in rodents, mice and rats, that have been used extensively to study pituitary development and function. In all animals, the fleshy, glandular anterior pituitary is distinct from the neural composition of the posterior pituitary, which is an extension of the hypothalamus. The anterior pituitary arises from an invagination of the oral ectoderm and forms
Combined rapid anterior pituitary evaluation panel by TRH and rises in luteinizing hormone (LH) and follicle-stimulating hormone (FSH) caused by GnRH. Blood glucose levels are also monitored to ensure appropriate levels of hypoglycemia are achieved. The triple bolus test was introduced in 1973 by physicians from the London Royal Postgraduate Medical School and Queen Elizabeth Hospital, Birmingham. It followed earlier reports combining insulin and vasopressin analogues in the diagnosis of hypopituitarism.

A triple bolus test is usually ordered
