| Question | Answer |
|---|---|
| Parathyroids-we have | 4-2 on each lobel |
| Where is Parathyroid located: loc.: | embedded on posterior surfaces of lateral lobes of the thyroid |
| Describe parathyroid: | small round masses |
| Kinds of cells in parathyroid: | 2 kinds: Chief and Oxyphil |
| CHIEF (PRINCIPAL) cells: | major producers of parathyroid hormone (PTH), which increases calcium levels in blood |
| OXYPHIL CELLS: | These cells may synthesize a reserve capacity of PTH. This has not yet been proven |
| PTH is: | Parathyroid hormone |
| How many Adrenal Glands: | Two; One superior to each kidney |
| Adrenal Glands each have a: | cortex and medulla |
| Cortex is: | outer layer |
| Medulla is: | inner part |
| Cortex has 3 zones: | Zona Glomerulosa, Zona Fasciculata, Zona Reticularis |
| Zona Glomerulosa secretes: | MINERALOCORTICOIDS-which helps control water balance and electrolytes |
| Aldosterone assounts for ___% of: | 95%; mineral o corticoid activity |
| Zona Fasciculata sectetes: | GLUCOCORTICOIDS such as: cortisone, corticosterone & cortisol. Cortisol is most abundant.All work w/other hormnones to help requlate metabolism, provide resistance to stress and are anti-inflammatory |
| Zona Reticularis mainly: | secretes GONADOCORTICOIDS (sex hormones) |
| The Medulla contains hormone-producing: | cells called CHROMAFFIN cells, which surround large blood filled sinuses |
| The CHROMAFFIN cells produce: | epinephrine & norepinephrine |
| CATECHOLAMINES are: | epinephrine (formerly adrenolin) and norepinephrine |
| The catecholamines are based on: | the amino acid tyrosine |
| CWhat are fight or flight hormones: | epinephrine & norepinephrine |
| The Pancreas is known as: | a dual action gland |
| The pancreas has both exocrine &: | endocrine |
| Endocrine portion is: | PANCREATIC ISLETS or ISLETS OF LANGERHANS |
| Pancreatic islets consist of hormone-producing cells including: | Alpha, Beta, Delta & F-cells |
| Alpha Cells: | produce GLUCOGON |
| Glucogon is a hormone that: | puts glucose into blood from storage |
| Beta Cells: | produce INSULIN which takes glucose out of blood & into cells |
| Delta cells produce a: | peptide hormone that is identical to GH INHIBITING FACTOR (GHIF) |
| SOMATOSTATIN aka: | GH INHIBITING FACTOR, which inhibits the secretion of insulin |
| F-cells produce: | PANCREATIC POLYPEPTIDE (PP), which inhibits the gullbladder & regulates the secretion of pancreatic enzymes |
| Alpha & Beta work as a team to: | regulate homeostasis under direction of CNS |
