The pituitary gland (hypophysis cerebri) is derived from 2 sources. The anterior lobe is an upgrowth of ectoderm from the roof of the stomodeum (primitive buccal cavity), while the posterior lobe is a down growth of neuroectoderm from the diencephalon. 4th week: a diverticulum, Rathke’s pouch, grows upwards from the roof of the stomodeum towards the…
The Dexamethasone Suppression Test (DST) is based on the principle of negative feedback exerted by steroids on pituitary gland’s ACTH secretion. Negative feedback with exogenous steroid works if the cause is excessive ACTH secretion from pituitary: 1. Cushing’s disease (pituitary ACTH dependent Cushing’s syndrome): Excessive ACTH secretion by pituitary adenoma…
