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.

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. macula lutea n.

Wardrop Ess. Morbid Anat. Human Eye II. xli. 135 Besides the vascular and medullary lamina of the retina, there is a peculiar part of its structure called the Macula Lutea, discovered by Sömmerring... The macula lutea, which is observed near the centre of the retina, appears in the form of a spot of a yellow colour. 1967 G. M. Wyburn et al. Conc. Anat. viii. 206/2 In the centre of the retina is the yellow spot, the macula lutea. 1986 A. S. Romer & T. S. Parsons Vertebr.
