Question | Answer |
which endocrine organ is the president? | hypothalamus |
which endocrine organ is the vice-president? | pituitary |
which part of the pituitary is anterior? | adenohypophysis |
what is another name for the adenohypophysis? | pars distalis |
what are the 3 cell types in the adenohypophysis? | basophils, acidophils, chromophobes |
which is smaller, basophils or acidophils? | acidophils |
what are the three basophilic cells? what do they secrete? where are they found? | thyrotropes, corticotropes, gonadotropes; tsh, acth, fsh & lh; adenohypophysis |
what are the two acidophilic cells? what do they secrete? where are they found? | somatotropes and mammotrophs; growth hormone and prolactin; adenohypophysis |
what does acth do? where does this have its effect? | stimulates glucocorticoid synthesis; adrenal zona fasiculata and reticularis |
what does tsh do? where does this have its effect? | stimulates production of thyroid hormones; follicular cells |
what does fsh do? where does this have its effect? | stimulates follicle development and androgen-binding production in sertoli cells; ovaries and testes |
what does lh do? where does this have its effect? | stimulates steroidogenesis in ovarian follicles, corpus leuteum, and leydig cells (testosterone); ovary and testes |
what are the support cells for the neurohypophysis? what cell provides these with materials to do so? | pituicytes; herring bodies |
what two hormones are produced in the neurohypophysis? what do these hormones do? | adh and oxytocin; stimulates water resorbtion in the renal medulla; stimulates smooth muscle contraction (causes contractions and milk ejection) |
what are the two cell types of the thyroid? | follicular and parafollicular |
which cells are also called c cells? what do they produce? | parafollicular; calcitonin |
what cells are also called principle or epithelial cells? what do they produce? what kind of epithelium? | follicular; T3 and T4; simple cuboidal |
what is the pink in the thyroid glands? | inactive hormone (iodinated thyroglobulin) |
what disorder is the result of circulating immunoglobulin that binds and perpetually activates the tsh receptor? | hyperthyroidism (grave's disease) |
what disease is the result of autoimmune destruction of thyroid? | hypothyroidism (hasimoto's disease) |
describe morphology of hashimoto's disease? | infiltration of lymphs and plasma cells, may see germinal centers |
what does calcitonin do? | calcitonin suppresses bone resorption by inhibiting osteoclast activity |
thyroid produces more t3 or t4? which is more potent? | t4; t3 |
t3 or t4, which is converted to the other in the liver? | t4 converted to t3 |
where are parathyroid glands found and how many? | on posterior thyroid; 4 |
what cells are in the parathyroid gland? what is their function? | principle cells and oxyphil cells; secretes parathyroid hormone, which increases osteoclast activity; oxyphil cells is unknown |
parathyroid principle cells are sometimes called what? | chief cells |
what does the zona glomerulosa secrete? what does it regulate? | aldosterone (mineralocorticoids); blood pressure via salt resorbtion |
what does the zona fasiculata secrete? what does it regulate? | glucocorticoids (cortisol and corticosterone); carbohydrate metabolism to raise blood glucose |
what does the zona reticularis secrete? what does it regulate? | androgens DHEA and androstenedione; sex hormones |
what does the adrenal medulla secrete? | norepinephrine and epinephrine |
where is the pineal gland located? what is its function? | near ventricles of brain; controls 24 hour cycles and hormonal levels, senses light and dark |
what are the 3 cell types of the pancreas? what do they produce? what are their effects? | alpha, beta, delta; glucagon, insulin, somatostatin; raise glucose levels, lower glucose levels; inhibit release of insulin and glucagon |
where do enteroendocrine cells exist? | in pits of GI glands |
hypersecretion of cortisol leads to what disease? | cushing's syndrome |
hyposecretion of adrenal cortex leads to what disease? | addison's disease |
