the sympathetic axons extend to which blood vessels of the kidney?

□ juxtaglomerular apparatus
□ arcuate arteries
□ efferent arteriole
□ afferent arteriole
□ interlobar arteries

Explanation:

The sympathetic nervous system innervates the afferent arterioles of the kidney. When activated, it causes vasoconstriction of the afferent arterioles, reducing blood flow to the glomerulus and thus glomerular filtration rate. The juxtaglomerular apparatus (which includes granular cells in the afferent arteriole wall) is also innervated by sympathetic axons. Sympathetic stimulation can cause the granular cells to release renin. The efferent arteriole, arcuate arteries, and interlobar arteries are not the main targets of sympathetic axons in terms of the primary regulation relevant to the immediate functional response (like in the "fight - or - flight" response affecting renal blood flow and filtration).

Answer:

Juxtaglomerular apparatus, Afferent arteriole
