Video at a Glance
- The hypothalamus is considered the master gland, as it controls the majority of the endocrine system.
- The pituitary gland is located beneath it.
- The pituitary gland is divided into anterior and posterior lobes.
- The anterior lobe has a unique anatomy and vascular supply containing two capillary beds separated by a portal vein that transmits blood.
- The anterior lobe communicates with the hypothalamus to secrete releasing hormones that inform the pituitary to release more hormones.
- The posterior lobe is an extension of the hypothalamus, as hormones created in the nerve soma of the hypothalamus travel down for storage and release in the posterior lobe.
