Question

During ovulation, the Graafian follicle empties its contents outside. It then regresses into

• A. corpus spongiosum
• B. corpus luteum
• C. corpus albicans
• D. corpus callosum

Answer 1

The correct option is B corpus luteum

After the Graafian follicle is ruptured and its contents are emptied to the outside under the influence of LH surge, the ruptured Graafian follicle transforms into corpus luteum. It is also called the yellow body. This transformation also occurs under the influence of LH.
The corpus luteum has a secretory activity. It secretes progesterone. In the absence of fertilisation, the secretory activity of the corpus luteum declines and it regresses into corpus albicans. It is also called white body.
Corpus callosum is a large, C- shaped nerve fibre bundle which stretches across the midline of the brain, connecting the right and left cerebral hemispheres.
Penis is the secondary male reproductive organ. Its body is composed of 3 cylindrical masses of tissues- 2 corpora cavernosa and 1 corpus spongiosum. Corpus spongiosum contains the spongy urethra and keeps it open during ejaculation.
