Study Notes
Pituitary Gland Composition
- The posterior lobe of the pituitary gland is composed of nervous tissue and does not produce hormones on its own.
Posterior Pituitary Supply
- The posterior pituitary lobe is supplied by the hypothalamo-hypophyseal tract, which carries hormones produced by the hypothalamus.
Posterior Pituitary Hormones
- Posterior pituitary hormones, such as oxytocin and antidiuretic hormone (ADH), are synthesized in the hypothalamus and transported to the posterior pituitary gland for storage and release.
Anterior Pituitary Function
- The primary function of the anterior pituitary lobe is to regulate the production and secretion of various hormones that stimulate or inhibit the production of hormones by other endocrine glands.
Anterior and Posterior Pituitary Differences
- The main difference between the anterior and posterior pituitary lobes is that the anterior lobe produces and secretes its own hormones, whereas the posterior lobe stores and releases hormones produced by the hypothalamus.
Test your knowledge of the pituitary gland with this quiz. Learn about its size, location, connection to the hypothalamus, and the two anatomically and functionally different lobes - the posterior and anterior lobes.
