Endocrine System ANP
| Question | Answer |
|---|---|
| Hypothalamus | Location: Brain Hormones: Many (no names) Function: stimulate or Depress effects on Pituitary |
| Pituitary (Hypophysis) | Location: Brain Hormones: In Anterior and Posterior Pituitary Function: Master Gland |
| Anterior Pituitary (Adenohypophysis) | 1. Growth hormone-bones, muscle, soft tissue 2. Thyroid stimulating hormone-formation/function of thyroid gland 3. Adreno Corticotropic hormone-formation/function of adreno cortex 4. Follicle stimulating hormone- formation of ova/sperm |
| Anterior Pituitary Continued... | 5. Luteinizing hormone-manufacture/secrete progesterone, estrogen, testosterone 6. Prolactin-function of milk producing and breast tissue |
| Posterior Pituitary (Neurohypophysis) | Hormones-1. ADH- Anti Diaretic Hormone - Causes water retention 2. Oxytocin - uterine contraction during labor/delivery and breast feeding |
| Thyroid *iodide necessary for formation of hormones* | Location- Ventral aspect of the Trachea (windpipe) Hormones- Triiodothyroid T3 - regulation of metabolic rate. Thyroxine T4 - more you have the faster metabolic rate. |
| Parathyroids | Location- embedded in each lobe of the thyroid Hormones- PTH-Parathyroid hormone Function- bones releases calcium when calcium is low |
| Adrenal Cortex (outer portion) | Location- one on top of each kidney (STEROIDS) 1.Mineralocorticoids-aldosterone-sodium retention potassium loss 2.Glucocorticoids-cortisol-regulate use of protein, carbs, fats 3.Gonadocorticoids-Androgen-testosterone and -estrogen-2nd sex characteristi |
| Adrenal Medulla (inner portion)FIGHT OR FLIGHT | "Catacholamines" Location- on on top of each kidney Hormones- 1.Adrenaline(epinephrine) 2.Noradrenaline(Norepinephren) Both Dilate centrally (Head trunk veins etc) Constrict peripherally (limbs) HR ^ BP ^ RESP ^ |
| Islets of Langerhans | Location- Pancreas Hormones- 1. Insulin- allows glucose to enter cells 2. Glucagon- allow glycogen back into glucose |
| Ovaries | Location- female pelvic hormones- 1.Estrogen- 2nd sex characteristics 2. Progesterone- thickening uterine wall. |
| Testes | Location- male pelvic Hormone- testosterone Function- male sex characteristics |
| Pineal Gland | Location- Brain Hormone- Melatonin Function- Secretes in darkness. Responsible for awake/sleep. Biorhythms |
| Placenta | Location- Female pelvic Hormones- 1.Progesterone - thick uterine wall 2.HCG-Human Corionic Gonadatropin |
| Erythropoietin | Location- kidney Function- from RBC through bone marrow |
| ANP - Atrial Naturietic Peptide | Location- Heart Function- Diaretic H20 loss + sodium loss |
