3. Example…. There is a Female hormone called Follicle Stimulating Hormone (FSH) which tells the ovaries to do one thing only and that is to produce a group of hormones called estrogens.…
17. The female gonads, or ovaries, under the influence of FSH, develop mature folliclescontaining an oocyte. The follicle cells secrete the hormone estrogen that causes the lining of the uterus to build up. A LH spike causes ovulation, and the surrounding follicle tissue develops into a corpus luteum that now also makes progesterone. Under the influence of progesterone, the lining of the uterus develops secretions to sustain an early embryo. If there is no production ofGnRH by the early embryo, the corpus luteum shrinks and the lining of the uterus sloughs in the process called…
The uterus is made up of extremely flexible tissues that can stretch at a rapid rate to accommodate foetal growth. The female reproductive system also has ovaries which release ova whilst producing and regulate hormones, and fallopian tubes with connect the uterus to the ovaries and provide transportation for the oocyte to the womb.…
It also provides nutrients for the embryo once it is formed until it sinks into the uterus where the placenta can take over. In the human body, the ovum is about the size of a sesame seed, or approximately 0.12 mm in diameter. The reason why it is so large is because it contains all organelles, materials, and nutrients for the growth and development of the embryo as well as a layer of padding which protects valuable information in the nucleus. So what kind of organelles do ovum cells have and what are their functions?…
5.) Oestrogenic- any of the several steroid hormones, that are secreted chiefly by the ovaries and placenta, that induces oestrus, stimulus changes in the female reproductive organs during the oestrus cycle, and promote development of female secondary sexual characteristics.…
The organ is anatomically divided into several sections: the uterine body (corpus uteri) with the uterine cavity in the interior forms the upper two-thirds of the uterus. In the upper part, the fundus, open the right and left, the two fallopian tubes (tubes). About you get eggs from the ovaries (ovarian) into the uterine cavity. The muscular uterine body is internally lined with a mucous membrane, the so called endometrium.…
Polycystic ovary syndrome is also known as Stein-Leventhal syndrome. It is a condition that affects the ovaries. Ovaries with women consist of a pair of glands that are either side of the uterus. They produce ova {eggs} that are released into the uterus once a month during the menstrual cycle. Each ovum develops in the ovary from a small swelling called a follicle. Several of these follicles develop each month , but only one will produce a full matured ovum. Ovaries can produce a variety of hormones including the female hormone we know as estrogen. Ovaries produce a small amount of androgens, such as testosterone, which are sometimes called male hormones. When a woman has polycystic ovary syndrome the ovaries are affected. Although there…
Endocrine system: the main function of the endocrine system is the glands and the hormones. They produce and release hormones into the body via the blood. The endocrine system controls, organ, cells, growth development, puberty, tissue function, metabolism and also plays a part in controlling mood. It works by releasing hormones in response to a change in the structure or function of the body.…
