• Midline of middle cranial fossa • Rests in hypophysial fossa of sphenoid bone Description: • Small, oval bilobed endocrine gland • Two functional lobes: anterior (adenohypophysis) and posterior (neurohypophysis) • Connected by infundibulum to hypothalamus Function: • Anterior pituitary produces the following hormones: thyroid-stimulating (TSH), prolactin (PRL), adrenocorticotropic (ACTH), growth (GH), luteinizing (LH), melanocyte-stimulating (MSH), and follicle-stimulating (FSH) • Posterior ______ stores and releases: antidiuretic hormone (ADH) and oxytocin (OT) |

Location:
• Diencephalon (epithalamus) Description: • Pea-sized endocrine gland • Attached to roof of third ventricle Function: • Secretes melatonin (involved in sleep/wake cycles) • Modified activity in endocrine organs (pituitary, pancreas, parathyroid, suprarenal, and gonads) |
