Study Notes
- The anterior and posterior pituitary have different embryological origins.
- The posterior pituitary is derived from a downgrowth of nervous tissue from the hypothalamus.
- The anterior pituitary arises as an epithelial upgrowth from Rathke's pouch.
- The adenohypophysis is the specialized glandular epithelium that wraps around the anterior aspect of the posterior pituitary.
- The posterior pituitary secretes antidiuretic hormone (ADH) and oxytocin, while the anterior pituitary secretes various hormones controlled by releasing hormones.
- ADH and oxytocin are synthesized in the hypothalamus and stored in the posterior pituitary.
- Posterior pituitary hormone release is controlled directly by nervous impulses from the hypothalamus.
- Anterior pituitary hormone release is controlled by specific hypothalamic releasing hormones.
- Prolactin secretion is under the inhibitory control of dopamine, and growth hormone secretion is controlled by both releasing and inhibitory hormones.
- The pars intermedia synthesizes and secretes melanocyte-stimulating hormone (MSH), but its physiological importance and control of secretion are poorly understood in humans.
