| Question | Answer |
|---|---|
| Hormone:oxytocin Gland: Action: | Gland:hypothalamus Moves to posterior pituitary for storage |
| Hormone: antidiuretic ADH Gland: Action: | Gland:hypothalamus; Moves to posterior pituitary for storage |
| Hormone:oxytocin Gland: Action: | Gland:Posterior Pituitary;Initiates laber, initiates milk let down |
| Hormone:antidiuretic hormone ADH Gland: Action: | Gland:Posterior Pituitary; Decreases urine formation. Acts on kidney tubules. Vasocontriction |
| Hormone:growth hormone GH Gland: Action: | Gland:Anterior Pituitary; Stimulates bone and skeletal muscle growth |
| ADH disorders: | Hyposecretion-diabetes insupidus; Hypersecretion- fluid retention, brain edema |
| GH disorders: | Hyposecretion: dwarfism; Hypersecrection: Gigantism, Acromegaly |
| Hormone:Prolactin PRL Gland: Action: | Gland:Anterior Pituitary; Stimulates milk production |
| Hormone:Follicle stimulating hormone FSH Gland: Action: | Gland:Anterior Pituitary; Tropic; Stimulates ovarian follicles, production of estrogen, stimulates sperm production |
| Hormone:Luteinizing hormone LH Gland: Action: | Gland:Anterior Pituitary; Tropic; Triggers ovulation |
| Hormone:Adrenocorticotropic hormone ACTH Gland: Action: | Gland:Anteror Pituitary; Tropic Promotes release of glucocorticoids and androgens from adrenal cortex |
| Hormone:T3 triiodothyronine / Gland, Action | Gland: Thyroid; Increases metabolism, blood pressure, regulates tissue growth |
| Hormone:T4/Gland,Action | Gland: Thyroid; Increases metabolism, blood pressure, regulates tissue growth |
| What are the three thyroid disorders? | Graves Disease-hyperthyroidism; Cretinism-hypothyroidism(infants); Myxedema-hypothyroidism(adults) |
| Hormone:Calcitonin/Gland, Action | Gland: Thyroid; Childhood regulation of blood calcium levels through uptake by bone. |
| Hormone:Parathyroid Hormone PTH / Gland, Action | Gland: Parathyroid; Increases blood calcium levels through action on bone, kidneys, and intestine. |
| Hormone: Insulin / Gland, Action | Gland: Pancreas; released by beta cells; reduces blood sugar levels. |
| Hormone: Glucagon / Gland, Action | Gland: Pancreas; release by alpha cells; increases blood sugar levels. |
| What disorder is associated with the pancreas? | Type 1 DM -autoimmune destruction of beta cells, deficiency of insulin / Type 2 DM - resistance of peripheral tissues to accept insulin and inadequate insulin secretion. |
| Hormone: Epinephrine / Gland, Action | Gland: Adrenal Medulla; Short-term stress response; increased blood sugar, vasoconstriction, increased heart rate, blood diversion |
| Hormone: Norepinephrine / Gland, Action | Gland: Adrenal Medulla; Short-term stress response; increased blood sugar, vasoconstriction, increased heart rate, blood diversion |
| Hormone: Glucocorticoids / Gland, Action | Gland: Adrenal Cortex; Long-term stress response: increased blood glucose levels, blood volume maintenance, immune suppression. |
| Hormone: Mineralocorticoids / Gland, Action | Gland: Adrenal Cortex; Long-term stress response: blood volume and pressure maintenance, sodium and water retention by kidneys. |
| Hormone: Melatonin / Gland, Action | Gland: Pineal Gland; Circadian timing |
