Endocrine System
- Anatomy
- Hyptothalamus
- Forms floor and walls of brain 3rd ventricle
- Regulates primitive functions: water balance, thermoregulation, etc.
- Many functions carried out via pituitary gland
- Pituitary Gland (Hypophysis)
- Suspended from hypothalamus floor by stalk (infundibulum)
- Anterior Pituitary
- "Adenohypophysis" 3/4 of pituitary
- Liked to hypothalamus via "hypophyseal portal system"
- Network of "primary capillaries"
- Group of small "portal venules"
- Follicle-Stimulating Hormone
- Luteinizing Hormone
- Thyroid Stimulating Hormone
- Adrenocorticotropic Hormone
- Prolactin
- Growth Hormone
- Posterior Pituitary
- Composed of nervous tissue
- Signals through hypothalamus-hypopheseal tract
- Hormones are produced in hypothalamic neurons and move down via axoplasmic flow
- Stored in nerve endings until signal triggers release
