macula densa1942
1942 Lancet 3 Oct. 394/2 Zimmerman [sic] first recognised the different appearance of the cells of the distal tubule most closely applied to the afferent arteriole in its juxtaglomerular portion. In this part, the ordinary tubular cells seem aggregated, and become in some species much higher and more columnar. Because of this grouping together of nuclei, and the impression of increased density of epithelial cells produced, Zimmerman called this the macula densa.
1952 A. C. Allen Kidney ii. 32/2 The macula densa in combination with the juxtaglomerular body is referred to as the juxtaglomerular apparatus.
1968 E. L. Becker Struct. Basis Renal Dis. i. 34 The juxtaglomerular apparatus..is considered to consist of four portions: the specialized portion of the afferent arteriole containing characteristic granules; the first portion of the distal convoluted tubule, or macula densa; the cushion of cells at the vascular pole, continuous with the mesangium..; and the efferent arteriole.
1985 C. R. Leeson et al. Textbk. Histol. (ed. 5) xiii. 421/1 The cells also are closely related to the macula densa, a specialised region of the distal convoluted tubule at its commencement.
