Hormonal Control of the Menstrual Cycle Worksheet
What is a hormone? Chemicals that are produced in one part of the body and used in another
What system is responsible for the production of hormones? The Endocrine System
Sketch a picture of the female reproductive system. Include the oviduct, ovaries, uterus, cervix and vagina.
Where does the embryo undergo most of its development? Uterus
What is another name for the fallopian tube? oviduct
Where does fertilization take place? fallopian tubes
What is ovulation? Changes that occur to the ovaries during the menstrual cycle
What is the follicle converted to? Corpus Luteum
What happens during the flow phase? Hormone production stops
What happens during the follicular phase? Follicle gets bigger and produces a hormone which makes uterus lining thicker.
What happens during the luteal phase? Follicle is converted into a corpus luteum
What happens to the uterine lining during the first phase? It sloughs
What are the four hormones that control the menstrual cycle? LH, FSH, Progestrerone, Estrogen

reproductive questions in text
1. List the general functions of the male reproductive system. Produce the male sex cells, to transport these cells to the female reproductive tract, and to secrete male sex hormones.
7. Outline the process of meiosis. Two divisions; First and Second Meiotic Divisions. The first meiotic division seperates homologous chromosome pairs. Each is replicated and consists of chromatids. Each cells that undergo the second meiotic division emerges with one member of each homogous pair, a condition termed haploid.
8. List two ways that meiosis provides genetic variability.
10. Describe a sperm cell. tadpole-shaped structure about .06 millimeters long.
11. Describe the epidiymis, and explain its function. A tightly coiled, thredlike tube about 6 meters long. It connects the seminiferous tubules of the testes to the vas deferens.
20. Explain the mechanism that produces an erection of the penis. The spinal cord releases the vasodilator nitric oxide, which causes the arteries leading to the penis to dialate, increasing blood flow into erectile tissues. Consequently, blood accumalates in the erectile tissues, and the penis swells and elongates, producing an erection.
29. List the general functions of the female reproductive system. To produce and maintain the female sex cells, transport these cells to the site of fertalization, to provide a favorable environment for a developing offspring, to move offspring to the outside, and to produce female sex hormones.
33. Describe the structure of an ovary. The ovaries are subdivided into a medulla and a cortex, medulla composed of connective tissue, blood vessels, lymphatic vessesls,& nerves, the cortex contains ovarian follicles & is covered by cuboidal epithelium.
38. Define ovulation. The release of an oocyte from an ovary.
40. Describe the structure of the uterus. A hollow,muscular organ, shaped somewhat like an inverted pear.
49. Define menstral cycle. Recurring changes in the uterine lining of a woman of reproducting age.
54. Describe the process of fertilization. The union of an egg cell and a sperm cell.
58. Discuss the events that occur during the birth process. Fetal head forced toward cervix, cervix is stretched, stretched receptors are stimulated, Reflex is elicited that causes stronger uterine contractions, fetus is moved downward
61. Define contraception. A behavior or device that prevents fertalization.
62. List several methods of contraception, and explain how each prevents pregnancy. Birth control pills they distrupt the normal pattern of gonadotrophin & prevent the surge in LH release that triggers ovulation, injection of depo alters uterine lining making it less hospitable for developing embryo, implants prevents ovulation like birth control pills.
63. List several sexual transmitted diseases. gonorrhea, chlamydia, & aids.
7. Outline the process of meiosis. Two divisions; First and Second Meiotic Divisions. The first meiotic division seperates homologous chromosome pairs. Each is replicated and consists of chromatids. Each cells that undergo the second meiotic division emerges with one member of each homogous pair, a condition termed haploid.
