Study Notes
Structure of the Pituitary Gland
- The pituitary gland is a small, pea-sized gland situated at the base of the brain, encased within the sphenoid bone.
- Composed of two main parts: the anterior (adenohypophysis) and posterior (neurohypophysis) pituitary, each with distinct functions and origins.
Embryonic Tissue Origin
- The anterior pituitary is derived from the embryonic tissue that forms the roof of the mouth, specifically the oral ectoderm.
Neurosecretory Cells Location
- The cell bodies of neurosecretory cells that produce oxytocin and antidiuretic hormone (ADH) are located in the hypothalamus.
Alternative Name for Anterior Pituitary
- The anterior pituitary is also referred to as the adenohypophysis.
Connection with Hypothalamus
- The pituitary gland is connected to the hypothalamus by a stalk known as the infundibulum, which facilitates communication through hormones and neural signals.
