Endoderm→ convergence→ neural tube → neural groove → spinal cord Question 23 2 / 6 pts Name and discuss the stage of labor that best describes the figure below: Your Answer: cervix dilation The baby is pushed through the birth canal The first stage, dilation of the cervix, is the time it takes for the mother’s cervix to dilate to ten centimeters. During this stage the uterus contracts, which pushes the baby’s head against the cervix causing it to dilate (widen). This stage of labor is the longest, lasting, on average 6-10 hours. Oxytocin is a hormone that is released from the posterior pituitary gland to stimulate contractions in the 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. Just prior to ovulation, the cervix swells, softens and secretes mucus allowing sperm better access to and viability within the uterus. Question 8: Label the regions of the reproductive system below: (A-C) A: _______________ B: _______________ C: _______________ A: Prepuce B: Urethral orifice C: Vestibule Question 9: True or False: The mammary alveoli begin at the nipple and divides into numerous other lobules. True False **CAN ALSO ASK: True or False: Each mammary gland contains 12- 24 lobules. 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? 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: 1st trimester, 2nd trimester or 3rd 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 Question 22: Find the steps that correctly order neurulation: A. Ectoderm→ neural crest → convergence → neural groove → brain B. Endoderm→ neural groove → convergence → neural tube and neural crest C. Ectoderm→ convergence→ neural fold → neural tube → spinal cord D. Endoderm→ convergence→ neural crest → neural groove → spinal cord Question 23: Name and discuss the stage of labor that best describes the figure below: The first stage, dilation of the cervix, is the time it takes for the mother’s cervix to dilate to ten centimeters. During this stage the uterus contracts, which pushes the baby’s head against the cervix causing it to dilate (widen). This stage of labor is the longest, lasting, on average 6-10 hours. Oxytocin is a hormone that is released from the posterior pituitary gland to stimulate contractions in the myometrium of the uterus. As contractions continue, oxytocin is increasingly released until the baby is born. 5/11/2021 Module 6 Exam - Requires Respondus LockDown Browser + Webcam: Essential Human Anatomy & Physiology II with Lab-2021-Dalbey https://portagelearning.instructure.com/courses/877/quizzes/22991?module_item_id=135598 2/17 A.

Include specific locations, names, and amounts of time in your answer. An egg is usually fertilized in the ampulla of the fallopian tube and will stay there for about 3-4 days. It will undergo mitotic divisions here and proceed through the isthmus and into the uterus, where it will eventually implant itself into the endometrium once it undergoes more divisions and will become a blastocyst. The endometrium will have an increase in blood supply and provide a lot of nutrients to the blastocyst. The blastocyst will attach to the endometrium around day 7 and this is when the 3 layers of the blastocyst will start to form. 5/11/2021 Module 6 Exam - Requires Respondus LockDown Browser + Webcam: Essential Human Anatomy & Physiology II with Lab-2021-Dalbey https://portagelearning.instructure.com/courses/877/quizzes/22991?module_item_id=135598 13/17 Zygote→ morula→ blastocyst The zygote (fertilized egg) begins frequent mitotic cell divisions as it travels in the oviducts. The zygote spends about three to four days undergoing mitosis in the oviducts forming the morula and another three to four days undergoing mitosis while unattached in the uterus, forming the blastocyst as the endometrium prepares for implantation. Because of progesterone release from the corpus luteum, the endometrium increases its blood supply and secretes glycogen. The blastocyst implants into the endometrium of the uterus around day 7. 4 / 4 ptsQuestion 19 Which of the following is false concerning human cells? A. Haploid cells contain half the number of chromosomes (23). B. Diploid cells contain the full number of chromosomes (46). C. Gamete cells are haploid cells. D. A zygote has 23 chromosomes. Correct! E.

Glands, the intestines, the liver and the pancreas will come from the endoderm. From the mesoderm, the cardiovascular system as well as muscles and red blood cells will form. ● 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. 10 / 10 ptsQuestion 21 Label each of the following as occurring during the: 1 trimester, 2 trimester or 3 trimester 1.
