 pituitary gland (hypophysis) | A small oval endocrine gland attached to the base of the vertebrate brain and consisting of an anterior and a posterior lobe, the secretions of which control the other endocrine glands and influence growth, metabolism, and maturation. |
| (Adenohypophysis) anterior lobe of pituitary gland | consists of three regions that produce several hormones |
| posterior lobe of pituitary gland | contains the axons of hypothalamic neurons. stores and releases OT (oxytocin) and ADH (antidiuretic hormone) |
| Diabetes Insipidus | A disorder that develops when the neurohypohysis no longer releases adequate amounts of ADH, or when the kidneys cannot respond to ADH. |
| Diabetes mellitus | A disorder that damages many organ systems. Characaterized by blood glucose concentrations high enoughto overwhelm the kidney's reabsorption capabilities. |
| Posterior: Antidiuretic Hormone (ADH) | Stimulates the kidneys to reabsorb water, elevation of blood volume pressure. Target: Kidneys |
| Posterior: Oxytocin (OXT) | Stimulates contractions of uterus during childbirth; releases milk in nursing mothers. Contractions of ductus deferens and prostate gland. |
| Anterior: Follicle-Stimulating Hormone (FSH) | Stimulates production of mature eggs and sperm. |
| Anterior: Lutenizing Hormone (LH) | Stimulates ovaries and testes; prepares uterus for implantation of fertilized egg. |
| Anterior: Thyroid-Stimulating Hormone (TSH) | secretion of thyroid hormones |
| Anterior: Adreno-Corticotropic Hormone (ACTH) | Secretion of glucocorticoids (cortisol, corticosterone) |
| Anterior: Growth Hormone (GH) | Growth, protein synthesis, llipid mobilization and catabolism. |
| Anterior lobe: Prolactin (PRL) | Stimulates milk production in nursing mothers. |
| Anterior lobe: Melanocyte-Stimulating Hormone (MSH) | Stimulates the melanocytes of the skin, increasing their production of the skin pigment melanin. |
