2nd semester: Renal 6 Flashcards
Endocrine and micturition reflex (14 cards)
Major step in urinary bladder emptying
contraction of detrusor muscles
Mainly responsible for initiating the micturition reflex
stretch from the posterior urethra
you would suspect a sensory denervation of the urinary bladder if the patient
unnoticingly urinates
Major source of non-volatile acids:
oxidation of proteins and amino acids
contraction of the detrusor muscles in urination is made possible by which of the following junctional complex?
Nexus
vitamin D is rendered active by hydroxylation at the 1st carbon atom at which part of the kidney tubule?
proximal tubule
Hydroxylation of calcifediol is made possible by the action of a hormone synthesized by the
parathyroid gland
dominant mechanism of urine acidification during chronic acidosis:
formation of ammonia
Aside from the kidneys, erythropoietin can be synthesized by which tissue/organ in oxygen scarcity?
Brain
Renin secretion increases, if there is an increase in:
Renal sympathetic discharge
Bicarbonate reabsorption in the distal tubule is primarily associated with:
potassium reabsorption and hydrogen secretion
In the renal tubules, bicarbonate ions are reabsorbed in the form of:
CO2
Sign of partially compensated respiratory alkalosis
decrease in plasma levels of bicarbonate
the pudendal nerve innervates the:
external bladder sphincter
