The intrinsic and extrinsic controls of glomerular filtration rate ultimately involve changes in resistance at the afferent arteriole.

Question

Quizplus · Accepted Answer

Both intrinsic (autoregulation through myogenic and tubuloglomerular feedback mechanisms) and extrinsic controls (sympathetic nervous system and hormones) of glomerular filtration rate (GFR) can cause changes in the resistance of the afferent arteriole, thereby adjusting the rate of blood flow into the glomerulus and ultimately influencing GFR.
