macula lutea वाक्य

In the fovea centralis or macula lutea or simple yellow spot, cones predominate and are present at high density.
The yellow color and name of the corpus luteum, like that of the macula lutea of the retina, is due to its concentration of certain carotenoids, especially lutein.
The chief characteristics of the disease are progressive mental and physical enfeeblement; weakness and paralysis of all the extremities; and marasmus, associated with symmetrical changes in the macula lutea.
For example, it has been suggested that " meso "-zeaxanthin of trout integuments is derived from astaxanthin, and " meso "-zeaxanthin in primates ( macula lutea ) is derived ( at least in part ) from lutein.
The yellow color of the human macula lutea ( literally, " yellow spot " ) in the retina of the eye results from the lutein and zeaxanthin it contains, both xanthophylls again requiring a source in the human diet to be present in the eye.
