The anterior and posterior lobes of the pituitary differ in that _____.
sleet_krkn [62]

Answer:

many anterior pituitary hormones regulate other endocrine glands whereas posterior pituitary hormones regulate nonendocrine tissues

Explanation:

Anterior pituitary or adenohypophysis is the anterior lobe of the pituitary gland. Secretion of endocrine cells of the anterior pituitary is controlled by regulatory hormones released by hypothalamus. The hypothalamic releasing hormones bind to anterior pituitary endocrine cells, upregulating or downregulating their release of hormones. Anterior pituitary hormones stimulate endocrine glands: FSH and LH (ovaries and testes), TSH (thyroid), and ACTH (adrenal cortex).

Posterior pituitary or neurohypophysis is the posterior lobe of the pituitary gland. It  is not glandular it is just a collection of axonal projections from the hypothalamus. Posterior pituitary hormones regulate nonendocrine tissues: ADH-vasopressin (kidney tubules) and oxytocin (mammary glands, uterine tissues, brain).
