| Question | Answer |
|---|---|
| 3 parts of anterior pituitary | pars distalis, pars intermedia, pars tuberalis |
| pituitary gland is cradled by | the stella turcica |
| pars distalis hormones | gonadotropins, adrenocorticotropic, thyrotropic, growth hormone, prolactin |
| gonadotropins | FSH, LH |
| adrenocorticotropics | ACTH |
| thyrotropic | TSH |
| Pars intermedia | melanocyte stimulating hormone, not active in adults |
| posterior lobe of pituitary | pars nervosa |
| median eminence of hypothalamus | neuroglia secrete regulatory factors |
| pars nervosa/ post pituitary | no synthesis of hormone- stores for hypothalamus |
| hypophyseal tract | carries hormone |
| pituicytes | neurons of the glial cells |
| hormones of pars nervosa | oxytocin, antidiuretic hormone |
| hypophyseal portal system | 2 sets of capillary beds |
| hormones of the thyroid | T3, T4, calcitonin, |
| thyroid follicle | the whole cell |
| colloid | fluid filling the follicular cavity |
| follicular cells | secrete thyroglobin which turns into T3 & T4 |
| parafollicular cells | produce calcitonin which regulates calcium |
| parathyroid | on posterior surface of thyroid gland |
| cells of parathyroid | chief cells and oxiphils |
| chief cells secrete | parathyroid hormone, monitors calcium secretion |
| Adrenal Gland parts | adrenal cortex and adrenal medulla |
| three stages of adrenal cortex | zona glomerulosa, zona fasciculata, zona reticularis |
| zona glomerulosa | secretes mineralcorticoids |
| zona fasciclata | secretes glucocorticoids |
| zona reticularis | secretes gondococorticoids |
| adrenal medulla | flight or fight - produce epinephrine & norepi |
| chromaffin cells | produce epi & norepi |
| Pancreas | islets of langerhans, alpha and beta cells |
| alpha cells | secrete glucogon- stains red |
| beta cells | secrete insulin - stains blue |
| Thymus | located in mediastinum |
| Thymus produces | thymosin |
| medulla of thymus | distinct in infants |
| Pineal body | pineal sand - produces melatonin |
| Gonads | Ovary , testes |
| ovary hormones | estrogen, progesterone |
| testes hormones | testosterone |
