Question

How macula lutea and corpus luteum are related?
A) Both contribute to maintaining pregnancy
B) Both are a source of hormones
C) Both are characterised by their yellow colour
D) Both are found in human ovaries

Answer 1

Hint: Macula lutea is a part of the retina that is responsible for sharp detailed and central vision. The macula lutea contains a high concentration of cones. Whereas, women’s menstrual cycle consists of two phases; the follicular phase and the postovulatory or luteal phase. During this time, corpus luteum forms inside the ovary.

Complete step by step answer: Macula lutea in anatomy is a small yellowish area of the retina near the optic disc that provides central vision. When the gaze is fixed on any object, the centre of the macula, the centre of the lens, and the object are in the straight line. In the centre of the macula, is a depression which is called the phobia. It contains specialised nerve cells that are exclusive of the type known as cones. ARMD is a relatively common condition in people over the age of 50. Wet ARMD advances more quickly and is more severe than dry ARMD, which is characterized by the presence of drusen, i.e. a tiny yellow deposit on the retina and loss of retinal pigment. On the other hand, the Corpus luteum is made up of follicles that house maturing eggs. Both corpus luteum and macula lutea are characterised by yellow lutein. It occurs as a yellow spot.
Hence, the correct answer is option C.

Note: The primary purpose of the Corpus luteum is to pulse out hormones, including progesterone. Progesterone is required for a viable pregnancy to occur and to continue. A corpus luteum defect can be caused by many conditions like too high or too low body mass index, an extreme amount of exercise for a short luteal phase and many more.
