The endocrinal structure formed after ovulation (release of ovum from Graafian follicle) is
Open in App
Solution
The correct option is C Corpus luteum
Ovulation is triggered by a surge of luteinizing hormone (LH) from the anterior pituitary. After ovulation, the follicle lining cells develop into the corpus luteum (yellow body), under the influence of LH from the anterior pituitary. The corpus luteum produces the hormone progesterone and some estrogen. If the ovum is fertilised, it embeds itself in the wall of the uterus, where it grows and develops and produces the hormone human chorionic gonadotrophin (hCG), which stimulates the corpus luteum to continue secreting progesterone and oestrogen for the first 3 months of the pregnancy, after which time this function is continued by the placenta. If the ovum is not fertilized the corpus luteum degenerates and a new cycle begins with menstruation. At the site of the degenerate corpus luteum an inactive mass of fibrous tissue forms called as the corpus Albicans.
Corpus callosum is found in the central nervous system. The cerebrum is the largest part of the brain and it occupies the anterior and middle cranial fossae. It is divided by a deep cleft, the longitudinal cerebral fissure, into right and left cerebral hemispheres, each containing one of the lateral ventricles. Deep within the brain, the hemispheres are connected by a mass of white matter (nerve fibers), called as the corpus callosum. Corpus striatum is a striped mass of white and grey matter situated in front of the thalamus in each cerebral hemisphere.Therefore, the correct answer is option C.
