Human Reproduction MCQ Questions NEET Biology with Answers
IMPORTANT POINTS
The human is unisexual and viviparous. Reproduction is the mechanism by which continuation of generation is sustained. like all other vertebrates human also exhibits sexual dimorphism.The male and Female reproductive systems are organized by several types of organs.The organs of the male reproductive system are one pair of testes, one pair of epididymis, one pair of vas deferens, one pair of seminal vesicles prostate gland bulbourethral gland, urethra and penis. Female reproductive system consists of one pair of ovaries, the uterine tubes, uterus vagina, external genitalia and mammary glands.
To produce gametes ,gametogensis occurs in both male and female.The male gamete is known as sperm and female gamete is known as ovum.The process of sperm production is known as spermatogenesis and ovum production is known as oogenesis.
Menstrual cycle is the events of the cyclic changes in the endometrium, which it goes through month after month as it responds to changes in the levels of female sex hormones in the blood.
The one sperm and one ovum become involved in fertilization.A diploid zygote nucleus is formed through the fusion of male and female pronucleus.Now fertilized ovum is called zygote. During movement of zygote in to oviduct cleavage occurs.The embryo with 16 cells is called morula. Now the process of implantation of embryo take place The period of development of young one in female reproductive system is known as pregnancy. It takes approximately 266 to 280 days. The process of child birth is called parturition. The mammary glands of the mother under go differentiation during pregnancy and start producing milk after delivery this process is called lactation.
