Paracrine feedback from the ________ in the distal tubule to the granular cells stimulates release of ________.

Question

Quizplus · Accepted Answer

The macula densa in the distal tubule senses changes in sodium concentration and sends paracrine signals to the granular cells in the afferent arteriole, stimulating the release of renin. Sympathetic neurons release norepinephrine, not epinephrine, and do not directly stimulate renin release. The liver produces angiotensinogen, but it is not involved in paracrine feedback between the distal tubule and granular cells.
