Where are extraglomerular mesangial cells (Lacis cells) located?
Show answer and explanation
Correct answer: Between the afferent and efferent arterioles
Lacis cells are found in the triangular space between the afferent arteriole, efferent arteriole, and the macula densa. They are part of the juxtaglomerular apparatus and communicate with the intraglomerular mesangial cells.
