Test: Male & Female Reproductive System - NEET MCQ

• Cervix: The cervix is the lowest part of the uterus. It’s lined with a smooth mucous membrane and connects the uterus to the vagina.
• Glands in the cervical lining usually produce a thick mucus. However, during ovulation, this becomes thinner to allow sperm to easily pass into the uterus.

Hence, the Correct Answer is A

• Seminal plasma is the fluid part of semen and is contributed by seminal vesicles, prostate gland and bulbourethral glands. Seminal vesicles contribute fructose, citric acid and other nutrients as well as fibrinogen and prostaglandin.
• Secretions from prostate gland contain calcium ions, phosphate Ion, etc. and are alkaline in nature.
• Bulbourethral glands secrete alkaline mucus which is important for the lubrication of penis.

Hence, the Correct Answer is C

• Secondary sexual characteristics develop during puberty, such as breast enlargement and nipple erection, growth of body hair, most prominently underarm and pubic hair.
• Greater development of thigh muscles behind the femur rather than in front of it, hip widening, lower waist to hip ratio than adult males, smaller hands and feet than men, rounder face, and development of sexual organs.
• Estrogen is responsible for the developement of female secondary sexual characters.
• Progesteron is the pregnancy hormone.

Hence, the Correct Answer is A

• The testes are situated outside the abdominal cavity within a pouch called scrotum.
• The scrotum helps in maintaining the low temperature of the testes (2-2.5°C lower than the normal internal body temperature) necessary for spermatogenesis.

Hence, the Correct Answer is B

• Each testicular lobule contains one to three highly coiled seminiferous tubules in which sperms are produced.
• Each seminiferous tubule is lined on its inside by two types of cells called male germ cells (spermatogonia) and Sertoli cells.
• The male germ cells undergo meiotic divisions finally leading to sperm formation, while Sertoli cells provide nutrition to the germ cells.

Hence, the Correct Answer is D

The infundibulum leads to a wider part of the oviduct called ampulla

• The Leydig cells are located in the interstitial spaces between the seminiferous tubules.

Function: They synthesise and secrete androgen hormones (like testosterone).

Hence, the Correct Answer is C

The finger-like projections called fimbriae play a crucial role in the female reproductive system by aiding in the collection of the ovum after ovulation. These fimbriae help to guide the released egg from the ovary into the fallopian tube, where fertilization typically occurs. This process is essential for the successful transport of the ovum towards the uterus for potential fertilization.
