Question 17

5 / 5 pts

Name and discuss the purpose of the region of sperm indicated by the arrow in the figure below. The midpiece contains numerous mitochondria that generate the locomotive energy needed by the sperm. Tremendous amounts of energy

are needed to swim all the way through the female reproductive tract to contact an ovum.

Question 18

5 / 5 pts

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

4 / 4 pts

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).

Correct! C. Gamete cells are haploid cells. D. A zygote has 23 chromosomes. E. A&B are true

Question 20

6 / 6 pts

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

10 / 10 pts

Label each of the following as occurring during the: 1st trimester, 2nd trimester or 3rd trimester

1. Eyes begin to detect light and dark: 2nd trimester
2. Heart beat begins: 1st trimester
3. Fingerprints develop: 2nd trimester
4. Sucking reflexes established: 3rd trimester
5. Fat develops under skin: 3rd trimester

Question 22

4 / 4 pts

Find the steps that correctly order neurulation: Correct! A. Ectoderm→ convergence→ neural groove → neural tube → spinal cord B. Endoderm→ neural groove → convergence → spinal cord → neural tube C. Ectoderm→ neural tube → convergence → neural groove → brain D. Endoderm→ convergence→ neural tube → neural groove → spinal cord

Question 23

6 / 6 pts

Name and discuss the stage of labor that best describes the figure below:

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.

Which of the following statements is false concerning the vagina? Correct! The fundus is made of elastic fibers, blood vessels, lymph vessels and nerves. (The fundus is part of the uterus) 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

4 / 4 pts

Describe the purpose of the cervix during pregnancy. Your Answer:

The purpose of the cervix is to protect the uterus and fetus from pathogens and bacteria When a female becomes pregnant a mucus plug develops in the cervix and prevents any bacteria or pathogens from entering the uterus, thus protecting the health of the developing fetus. A firm, closed cervix also holds the developing fetus in the uterus until it reaches full term.
