Question

Both corpus luteum and macula lutea are

• A. found in human ovaries
• B. a source of hormones
• C. characterized by a yellow colour
• D. contributory in maintaining pregnancy

Hint:

The region in the eye responsible for the center and detailed vision is the macula lutea region of the retina.  This region has several cones. During the woman's menstrual cycle, the prominent phases are the follicular phase and the postovulatory or luteal phase. The corpus luteum forms inside the ovary during this time.

Answer 1

The Correct Option is C

Both corpus luteum and macula lutea are characterized by a yellow colour. 

In the human anatomy, the macula lutea is a tiny yellowish spot of the retina that facilitates central vision near the optic disc of the retina. In the ovaries, the Corpus luteum is made up of follicles that house mature eggs. Yellow lutein is found in both the corpus luteum and the macula lutea. It appears as a yellow spot on the skin. Once the egg is released from the ovary, the cells that line the ovarian follicle change shape and colour to become a corpus luteum (yellow body). Lutein, zeaxanthin, \(\alpha\)-carotene and \(\beta\)-cryptoxanthin are responsible for its yellow colouration.
