Pituitary gland
Glandula pituitaria
A pea-sized gland located in the sella turcica of the sphenoid bone, connected to the hypothalamus by the infundibulum (pituitary stalk). The anterior lobe (adenohypophysis) produces six major hormones. The posterior lobe (neurohypophysis) stores and releases oxytocin and ADH produced by the hypothalamus.
Function
The master endocrine gland, producing hormones that regulate growth (GH), reproduction (FSH, LH, prolactin), thyroid function (TSH), adrenal function (ACTH), and water balance (ADH). Coordinates the activity of other endocrine glands.
Clinical Significance
Pituitary adenomas can cause hormone excess or deficiency. Acromegaly results from excess growth hormone. Cushing's disease results from excess ACTH. Pituitary apoplexy is acute hemorrhage or infarction of the gland. Diabetes insipidus results from ADH deficiency.
