|
Diencephalon |
General term referring to: thalamus, hypothalamus, epithalamus, and subthalamus |
|
|
Hypothalamus Functions |
- regulates essential functions for individual and species survival - Integrates functions of endocrine, autonomic, somatic motor, and limbic systems. |
|
|
Hypothalamus Anatomical Location |
Inferior and anterior to thalamus |
|
|
Set point |
"normal" physiological value. Hypothalamus receives sensory info and compares that to our biological set points. Adjustments are made to restore homeostasis (set point). |
|
|
Pituitary Gland Links 1. Neural path 2. Non-neural path |
1. neuroendocrine products into general circulation by the posterior section of the pituitary gland. (neurohypophysis) 2. regulatory hormones into portal plexus of anterior pituitary gland. (adenohypophysis) |
|
|
Posterior Pituitary Gland |
Hormones from hypothalamus are delivered to posterior pituitary via hypothalamo-hypophyseal tract. Capillaries in posteriori pituitary pick them up and deliver them to general circulation |
|
|
Anterior Pituitary Gland |
regulatory hormones produced by hypothalamus take this route: (primary capillary plexus --> secondary capillary plexus --> cause release of trophic hormones from anterior pituitary --> secondary capillary plexus --> general circulation) |
|
|
Adrenocorticotropic hormone (ACTH) |
primary stimulator of adrenal cortisol production |
|
|
Thyroid stimulating hormone (TSH) |
Stimulates thyroid gland to make T3 and T4 |
|
|
Follicle stimulating hormone (FSH) |
stimulates growth of ovarian follicles in ovary before egg is released at ovulation |
|
|
Luteinizing hormone (LH) |
Surge triggers ovulation and development of corpus luteum in females. aka ICSH in males. Stimulates leydig cell production of testosterone. |
|
|
Growth hormone (GH) |
promotes growth in children maintains normal body structure and metabolism in adults, including maintaining blood glucose levels. |
|
|
Prolactin (LTH) |
milk production |
|
|
Melanocyte stimulating hormone (MSH) |
stimulates melanogenesis in melanocytes
|
|
|
Interstitial cell stimulating hormone (ICSH) |
aka Luteinizing Hormone in females gametogenesis. Stimulates leydig cell production of testosterone. |
