2nd semester: Renal 6 Flashcards
Endocrine and micturition reflex
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
