Question

After ovulation, the endocrine part of ovary is
A. Corpus luteum
B. Corpus callosum
C. Corpus spongiosum
D. Corpus albicans

Answer 1

Hint: Corpus luteum may be a glandular structure developed from the ruptured Graafian follicle after the discharge of ovum i.e. ovulation. Prior to ovulation, an internal cell of ovarian follicles serves as a major source of endocrine hormones.

Complete answer:
After ovulation, endocrine acts as a short lived endocrine gland. It secretes a great quantity of progesterone and little amount of estrogen.
Ovulation is the release of an egg from one among a woman's ovaries. On discharging from the ovary, the egg travels down into the fallopian tube. At this part, fertilisation can be achieved by a sperm.
Ovaries have a primary role in the production of ova, despite this it also serves as an endocrine gland as it secretes two hormones, primarily estrogen and progesterone, these are very crucial to the normal fertility and reproductive development of a female.
An endocrine gland may be a mass of cells that forms in an ovary and is liable for the assembly of the hormone progesterone during early pregnancy. The role of the endocrine gland depends on whether or not fertilization occurs. Sometimes, cysts can form during an endocrine gland , which may cause painful symptoms. The endocrine (CL) may be a dynamic endocrine gland within the ovary that plays an integral role in regulation of the cycle and early pregnancy. The CL forms from cells of the ovarian follicle wall during ovulation.

So, from above discussion it can be concluded that the correct answer is option A.

Note:
Corpus luteum, yellow hormone-secreting body within the female genital system . Corpus luteum is formed at the location of a follicle (in an ovary), or sac, that has matured and released its ovum, or egg, within the process referred to as ovulation.
