Question Answer
receptive relaxationseotonin and nitric oxide from enteric NS allow for stomach relaxation
succus entericussecretions from exocrine glands in SI, includes mucus, water (helps bond-breaking for digestion), bicarbonate, NaCL
migrating myoelectric complex intense peristaltic contractions after meal that push everything from stomach through SI
haustration/segmentationcontractions of smooth muscle of LI (every 30 minutes)
what waste product is excreted from liver along with bile salts?bilirubin (worn out RBCs)
enterohepatic circulationbile salts enter duodenum, reabsorbed into blood, hepatic portal system, back to liver
by what hormonal mechanism are mass movements of the large intestine triggered?The gastrocolic reflex is triggered by gastrin and parasympathetic innervation
most dietary water is absorbed hereSI
amine hormone is derived fromtyrosine
permissive effectshormone needed for another hormone to be in full effect
what chemicals go into the synthesis of thyroid hormonestyrosine and iodide
what are the major effects on the body when TH concentration risesnormal functions (increase gene transcription, permissive of B-adrenergic recceptor expression, needed for CNS development and activity, and overall growth); too much (high heart rate, insomnia, weight loss, goiter, bulging eyes
what is the major secretion of adrenal medullacatacholamines
what functions do unstressed levels of cortisol support?anti-immune, premissive for adrenergic receptors in cardiovascular system, maintain glucose levels, fetal development
which organ and what specific cell types are insulin and glucagon secreted from?from pacreas-insulin from beta cells; glucagon from alpha cells
hormonal feedforward mechanism designed to prevent large glucose spikes during the absorptive phaseGIP is secreted from endocrine cells, which increases insulin before glucose enters blood
factors that oppose insulin1.glucagon 2.epinephrine 3.cortisol 4.growth hormone (requires energy)
what are the phases of uterine cyclemenstrual, proliferative, and secretory
factors known to cause amenorrheaathletic, anorexia nervosa, stress--loss of adipose, loss of leptin which is needed for normal production of GnRH/FSH/LH
adrenal cortex hormonessteroid: sex hormones, glucocorticoid, mineralocorticoid
two cells of testesleydig (like thecal); sertoli (granulosa)
