Question 16 6 / 6 pts Label the regions of reproductive system below: (A-E) To receive full credit you must name specific regions. A: B: C: D: E: Your Answer: A = corpus cavenosum B = gland pernis C = corpus spongiosum Question 18 5 / 5 pts Discuss the developmental steps of how a fertilized egg becomes implanted in the uterus. Include specific locations, names, and amounts of time in your answer. Your Answer: The egg release chemical that attract the sperm. The spern cell release enzymes that breaks the corona radiata, follicle cells surrounds the egg. Once this is accmplish more sperms releases acrosomal enzymes that make a hole in the egg allowing a sperm to pass through and a u 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. 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 Answer 1: Correct! 3rd trimester Answer 2: Your Answer: The first stage, dillation of the cervix, is the time it takes the mother's cervix to dillate to 10 cm. During this stage, the uterus contract which pushes the baby's head aganist the cervixcausing it to dillate. This stage is the longest between 6-10 hours. Oxytocin is a hormone that is released drom posterior pituitary glad to stimulates contraction. As contraction continues,oxytocin is increasingly releases until the baby is born. The second stage, delivery of the baby, is the time it takes for the baby to be pushed out of the birth canal after full dilation has been accomplished. During this stage a woman uses her abdominal muscles to push the baby, with the help of the uterus contracting, through the cervix and out the vagina. This stage is much shorter, lasting, on average, 50 minutes in a first delivery and 20 minutes in later ones. After the child is born the umbilical cord is tied and cut.
