EXAM
Question 1: All the following are functions of the ovaries EXCEPT: Production of eggs Maintaining the development of a fetus Production of estrogen Production of estrogen Development of the corpus luteum Question 2: Which of the following statements is true concerning oogenesis? It begins at the time of puberty. The primary oocyte divides to produce a secondary oocyte. Each primary oocyte produces in two to three mature ova. The first polar body maintains all the cytoplasm. B&C are true Question 3: Ovulation occurs when an egg is released from the. Ovarian follicle Question 4: Name the specific region of the reproductive system highlighted in blue below (also indicated by the arrow). **Cervix CAN ALSO ASK: Name the specific region of the reproductive system highlighted in blue below (also indicated by the arrow).
Fimbriae (infundibulum) Question 5: This layer of the uterus is shed monthly. Endometrium Mucosal coat Perimetrium Myometrium Serous coat ****CAN ALSO ASK:** This layer of the uterus contracts during labor. A. Endometrium B. Mucosal coat C. Perimetrium D. Myometrium E. Serous coat Question 6: Which of the following statements is false concerning the vagina? The fundus is made of elastic fibers, blood vessels, lymph vessels and nerves. The wetness and moisture of the surface is achieved by mucous from the cervix. The elastic fibers give the vaginal wall elasticity. The mucosal lining can extend. Question 7: Describe the purpose of the cervix prior to ovulation.
True False Question 10: True or False: Colostrum has a similar composition to milk but contains a lower concentration of protein. True False, it is a higher concentration of protein **CAN ALSO ASK: True or False: Milk is not produced during pregnancy because of the production of estrogen and progesterone. True False Question 11: Blood tests indicate that estrogen and LH levels are both elevated. Your patient is most likely in what phase of the female uterine cycle? Menstrual phase Proliferative phase Secretory phase Luteal phase Follicular phase **CAN ALSO ASK: Blood tests indicate that progesterone and estrogen levels are both increased. Your patient is most likely in what phase of the female uterine cycle? A. Menstrual phase B. Proliferative phase C. Secretory phase D. Luteal phase E. Follicular phase Question 12: Which of the following is false concerning the organs of the male reproductive system?
The epididymis is the site of sperm maturation. The vas deferens travels through the inguinal canal inside the abdomen. One produced, sperm travel to the seminal vesicles for maturation. The epididymis is located on the posterior-lateral portion of the testis. The testes function to produce sperm. Question 13: The connects the seminal vesicle with the urethra to allow sperm to exit the body. Ejaculatory duct Question 14: Match the gland/organ with the best description(s) A-F. Select all that apply. 1.Seminal Vesicles: D, F --fructose, prostaglandins 2.Prostate Gland: E --alkaline fluid 3.Bulbourethral glands: A, E --alkaline fluid, first secretion 4.Testes: C—produces sperm 5.Anterior Pituitary: B - -FSH Question 15: Which of the following is true concerning spermatogenesis?
D: Prostate gland E: Bulbourethral gland Question 17: Name and discuss the purpose of the region of sperm indicated by the arrow in the figure below. The head is almost entirely nucleus containing the cell DNA with a crown called the acrosome which contains enzymes that breakdown the membrane of the egg to allow the sperm to penetrate. Question 18: Discuss in detail the action of sperm needed to fertilize an egg. The egg releases chemicals that attract the sperm. Sperm cells release enzymes that break apart the corona radiata, follicle cells surrounding the egg. Once this is accomplished, more sperm release acrosomal enzymes that make a hole in the membrane of the egg, allowing one sperm cell to combine with the egg. When the union of egg and one sperm occurs, the membrane of the egg instantly chemically changes, preventing other sperm from penetrating the egg. Question 19: Which of the following is true concerning human cells? A. Haploid cells contain the full number of chromosomes (46). B. Diploid cells contain half the number of chromosomes (23). C.Gamete cells are haploid cells.
D. A zygote has 23 chromosomes. E. A&B are true Question 20: Discuss in detail the layers of cells (of the blastocyst) which form the embryo. ● Ectoderm- The skin and nervous tissue develop from the outer ectoderm layer. ● Endoderm- The inner endoderm layer forms the glands (thyroid, parathyroid and thymus), solid organs (liver and pancreas) and the lining of the hollow organs of the digestive and respiratory systems. ● Mesoderm- All other tissues, including the cardiovascular system, red blood cells, and muscle develop from the middle mesoderm layer. **CAN ALSO ASK: Discuss the supportive cells of the blastocyst and their purpose during pregnancy. (The amnion, placenta and umbilical cord.) The amnion forms a sac filled with fluid to cushion and protect the fetus. The placenta is a temporary organ that carries out nutritive, respiratory, excretory and endocrine functions for the embryo. The baby continues to grow in the uterus with nutrition provided by the placenta for nine months until it is time for delivery. The umbilical cord attaches the embryo to the placenta. Question 21: Label each of the following as occurring during the: 1 st trimester, 2 nd trimester or 3 rd trimester 1.Lungs fully mature: 3rd trimester 2.Lanugo develops: 2nd trimester 3.First fetal movements felt: 2nd trimester 4.Neurulation: 1st trimester 5.Testes descend to scrotum: 3rd trimester
