After puberty‚ the female produces an egg each month. Other changes take place on a cyclic basis including the uterus lining and hormone levels. These changes are called the menstrual cycle. Follicle stimulating hormone (FSH) from the pituitary gland stimulates the growth of follicles in the ovary. Follicles produce oestrogen that stimulates the pituitary to produce leutinising hormone (LH). As LH increases the size of the follicle increases until an egg is released. The corpus luteum formed in

language‚ which I agree completely. As can be noted in the text‚ by describing that an egg merely “drifts” through the fallopian tube while the sperm travels in a great “velocity” can subconsciously send the message that‚ even in biological terms‚ women are still weak and fragile while men are strong and powerful. As was also described in class‚ the penetrating aspect that “occurs” when the sperm binds to the egg‚ I thought‚ was a great observation because it reveals that in almost any context‚ the

transferred into gametes‚ or the reproductive sex cells‚ like the sperm and the egg. Then‚ during reproduction‚ the mutant gametes get transferred on to the new organisms DNA. Although both parents have mutations that they pass on to the child‚ most of the mutations come from the dad. While females are born with all of the eggs they will need in their lifetime‚ males constantly are making sperm cells. This constant replenishment of sperm causes more opportunities for a mutation to be transferred into

tightly coiled seminiferous tubules. a. The seminiferous tubules of each lobe empty sperm into another set of tubules‚ the rete testis‚ located at one side of the testis. Sperm travel through the rete testis to enter the first part of the duct system‚ the epididymis‚ which hugs the external surface of the testis. The interstitial cells produce androgens-the most important of which testosterone. Thus sperm-producing and hormone producing functions of the testes are carried out by completely different

saclike structures called ovarian follicles. Each follicle consists of animmature egg called an oocyte‚ surrounded by one or more layers of very different cells calledfollicle cells.The ovaries are for oogenesis-the production of eggs (female sex cells) and for hormone production (estrogen and progesterone). As the developing egg begins to ripen or mature‚ follicleenlarges and develops a fluid filled central region. When the egg is matured‚ it is called agraafian follicle‚ and is ready to be ejected from

its so important due to DNA holding the chromosomes that give each human unique physical traits. From there they begin discussing the process of meiosis‚ the process of male sperm and female eggs. They describe sperm being more about quantity‚ whereas the female egg is all about quality. When the male sperm and a female egg meet‚ they create a union of chromosomes‚ taking unique traits from both the male and female‚ creating an individual that has unique traits.
