Study Notes
Pituitary Gland
- Location: Base of the brain, connected to the hypothalamus by the pituitary stalk
- Function: Regulates various bodily functions by producing and secreting hormones that stimulate other endocrine glands
- Divisions:
- Anterior pituitary (adenohypophysis): Produces hormones that stimulate other endocrine glands
- Posterior pituitary (neurohypophysis): Stores and releases hormones produced by the hypothalamus
- Hormones produced:
- Growth hormone (GH)
- Adrenocorticotropic hormone (ACTH)
- Thyroid-stimulating hormone (TSH)
- Prolactin
- Oxytocin
- Antidiuretic hormone (ADH)
Thyroid Gland
- Location: Neck, anterior to the trachea
- Function: Regulates metabolism by producing thyroid hormones
- Structure:
- Two lobes connected by the isthmus
- Follicles: Functional units of the thyroid gland where thyroid hormones are produced and stored
- Hormones produced:
- Triiodothyronine (T3)
- Thyroxine (T4)
- Regulation:
- TSH from the pituitary gland stimulates the production and release of thyroid hormones
- Negative feedback loop: High levels of thyroid hormones inhibit the production of TSH
