Quiz 3 (25 pts: Dec 2, 2011) Name: _______________________________ Short answer and fill- in- the- blank. 1) Please list the four general steps involved in In vitro production of embryos. Additionally, please circle the step that would most likely be associated with intra- cytoplasmic sperm injection or ICSI (3 points)? a. Collection of immature oocytes c) Fertilization of mature oocytes (SHOULD BE CIRCLED) b. Maturation of immature oocytes d) Culture of embryos 2) Please Please list the three stages of parturition (3 points) a. Stage 1: Dilation of cervix b. Stage 2: Delivery of fetus c. Stage 3: Expulsion of placenta 3) For the four tissue types listed below, please indicate the order of tissue development during gestation using the numbers 1, 2, 3, and 4. The number 1 will be the earliest tissue to develop and the number 4 will be the latest to develop (2 pts). Fat: 4 Bone: 2 CNS: 1 Muscle: 3 4) Please describe three different physiological changes & two different behavioral changes that occur during the pre- parturition process in farm & companion animals. Please keep your answer brief and in the space provided (5 pts). a. Physiological 1. Vulva softens & becomes swollen 2. Cervix begins to dilate 3. Fetal positioning 4.
