Hypothalamus: Where is it? How big is it?what does it do? | Diencephalon, Tiny, Master Controller "Big Daddy" of this system |
Pituitary Gland aka hypophysisWhere is it? How big is it? Made of two lobes? | Sellatursica, pea size, Posterior Lobe- (Neurohypophysis) down growth of nervous tissue. Anterior Lobe- ( adenohypophysis) originates from an upgrowth of oral ecoderm (mouth) |
Posterior Lobe 2 hormones? | A: Oxytocin ( Uterus, breast smooth muscle, neurotransmitter effect).B: Antidiuretic hormone- target cells in DCT adn CD of Kidney. |
Anterior Lobe of Pituitary 9 Hormones | Adrenocorticotropic hormone (ACTH) Opiates:enkephalin, beta endorphinesMelanocyte Stimulating HormoneThyroid Stimulating Hormone (TSH)Growth HormoneFollicle Stimulating Hormone (FSH)Luteinizing Hormone (LH)Prolactin |
(ACTH) ADRENOCORTICOTROPIC HORMONE | Release-- corticotropic releasing hormone (CRH)TARGET CELLS OF ADRENAL CORTEX that secrete corisol. |
Two Opiates-- | Enkephalin & Beta endorphines |
Melanocytes Stimulating Hormone | act as neurotransmitters in humans. |
Thyroid Stimulating Hormone (TSH) | Release when the hypothalmus detects a low thyroid hormone TARGET CELLS: TSH goes to the thyroid and cause the release of thyroid hormone. |
Growth Hormone | Release--(GHRH) growth hormone releasing hormoneTrigger from hypothalamus to anterior pituitary to stop release (GHIH)growth hormone inhibiting hormoneTarget Cells: epiphyseal plates and muscle cells |
Follicle Stimulating Hormone (FSH) | Release-gonadotrpin releasing hormone (GnRH)Target Cells: stimulates sperm and egg production within gonads. |
Luteinizing Hormone (LH) | relase--gonadotropin releasing hormone (GnRH) TARGET CELLS: gonads- cause ovulation and release of estrogen, progesterone in females, and testosterone in males |
Prolactin | prolactin release hormone (PRH) to stop release PIH prolactin inhibiting hormone Target cells: mammary glands, Action: produces milk |
Thyroid Gland 2 Hormones | Thyroid Hormone, calcitionin |
Thyroid Hormone | iodine, two hormones T4 (thyroxine) and T3 (triiodothyronine) |
