The Female Reproductive System Worksheet. ____________________________ When will the ultimate levels of meiosis be completed? If fertilization does not occur, the corpus luteum lasts for ______________ days after which scars right down to kind the ___________________. The three phases of the ovarian cycle are follicular, ovulation and luteal. The endometrium begins to regrow, changing the blood vessels and glands that deteriorated in the course of the finish of the final cycle.
The remaining follicular cells at the moment are ________________________. ___________________________________________________________. The ovulated oocyte is arrested in metaphase of meiosis II. The thick glycoprotein membrane surrounding the oocye is the zona pellucida and the group of follicular cells that detach and journey with the oocyte are termed the corona radiata. The female menstrual cycle describes changes within the uterus and ovaries and is classically described as lasting 28 days with a variety of days.
There are a giant number of secretory __________________ on this layer. The vascular layer of the endometrium that’s superficial is the ________________________. The vascular layer that is everlasting is the _______________________.

The luteal and secretory phases refer to changes within the ruptured follicle. The cells in the follicle endure bodily changes and produce a structure called a corpus luteum. The corpus luteum produces estrogen and progesterone.
- The thin fold of mucous membrane on the terminal area of the vaginal canal known as the ________________________.
- These cells are called _________________________.
- There are roughly lobes which are subdivided into lobules which contain grape-like clusters of alveoli which produce the milk.
- External to the follicular cells stromal cells start to kind a layer called the ________________________.
The tissue is related and constructed as a unit to serve a typical operate. All organs of the body work in sync to kind about a dozen organ techniques. Vagina Picture The vagina is an elastic, muscular canal with a soft, flexible lining that gives lubrication and sensation. See a picture of the Vagina and study more about the health subject.

If fertilization does not happen, the corpus luteum lasts for 14 days after which scars right down to kind the corpus albicans. If fertilization does occur, the corpus luteum persists until the placenta is fashioned. The hormone human chorionic hormone secreted by the creating embryo causes the corpus luteum to persist. Proliferation of endometrial lining in first half of menstrual cycle. Pubertal changes of development of bones a muscular tissues, breast improvement, axillary and pubic hair, broadening of pelvis, voice modifications, distribution of adipose tissue. The feminine menstrual cycle describes modifications in the ______________ and _______________ and is classically described as lasting _______ days with a spread of __________ to __________ days.
Low ranges of progesterone allow the hypothalamus to ship GnRH to the anterior pituitary and cause the discharge of FSH and LH. FSH stimulates follicles on the ovary to develop and prepare the eggs for ovulation. As the follicles enhance in dimension, they begin to release estrogen and a low degree of progesterone into the blood. The degree of estrogen rises to a peak, causing a spike within the concentration of LH. This causes probably the most mature follicle to rupture and ovulation happens. Figure 13.17 The ovarian and menstrual cycles of feminine reproduction are regulated by hormones produced by the hypothalamus, pituitary, and ovaries.

The diagram beneath shows an ovary with the stages of growth of the ovum during an ovarian cycle. The hormones follicle-stimulating hormone and luteinizing hormone are released from the pituitary gland to stimulate the ovaries. Located next to the vaginal opening are glands that produce mucus generally recognized as Bartholin’s glands. At the junction of the labia minora is the clitoris, a small construction that is coated by a skin fold referred to as the prepuce. Just previous to the center of the cycle , the excessive degree of estrogen causes FSH and especially LH to rise quickly then fall.
The two inner folds that consist of mucous membrane are termed the labia minora. The thin fold of mucous membrane on the terminal area of the vaginal canal is called the hymen. The feminine external genitalia is collectively known as the vulva or pudenda.
Toward the tip of the third trimester, estrogen causes receptors on the uterine wall to develop and bind the hormone oxytocin. At this time, the baby reorients, facing ahead and down with the back or crown of the head engaging the cervix . This causes the cervix to stretch and nerve impulses are despatched to the hypothalamus, which indicators the discharge of oxytocin from the posterior pituitary. Oxytocin causes clean muscle in the uterine wall to contract. At the same time, the placenta releases prostaglandins into the uterus, growing the contractions. A constructive suggestions relay happens between the uterus, hypothalamus, and the posterior pituitary to assure an adequate provide of oxytocin.
