Question 2

1. Now – think about the gametes that are produced within both the male and female reproductive systems. Which of the following statements is incorrect? (1pt)

   		Male gametes are produced in the testes, female gametes are produced in the ovaries
   		Sperm reach final maturation and are stored within the epididymis
   		Ova don’t complete their final stage of meiosis until fertilized by sperm
   		Both spermatogonia and oogonia produce four mature gametes for each precursor cell following maturation

Question 3

1. Take a moment to consider the path that gametes take through the reproductive system. First, let’s examine the female reproductive system. Place the following structures in the order that they would be encountered by an ovulated ovum.

   -1.2.3.4.5.6.

   v agina

   
   -1.2.3.4.5.6.

   Cervix

   
   -1.2.3.4.5.6.

   Fimbriae

   
   -1.2.3.4.5.6.

   Infundibulum

   
   -1.2.3.4.5.6.

   Isthmus

   
   -1.2.3.4.5.6.

   Uterus

Question 4

1. Now, using the structures above, match the appropriate functional description to each structure.

   -A.B.C.D.E.F. Fimbriae -A.B.C.D.E.F. Infundibulum -A.B.C.D.E.F. Isthmus -A.B.C.D.E.F. Uterus -A.B.C.D.E.F. Cervix -A.B.C.D.E.F. v agina

   A. Allows copulation and the shedding of endometrium B. Terminal/uterine end of the oviduct C. Ovarian end of the oviduct, mucosa contains deep folds D. Sweep ova into oviducts E. Location of egg implantation and fetal development F. Muscular tube that helps maintain the fetus within the uterus

Question 5

1. Now, let’s do the same exercise for the male reproductive system. Place the following structures in the order that they would be encountered by sperm after leaving the seminiferous tubules of the testes.

   -1.2.3.4.

   Prostatic urethra

   
   -1.2.3.4.

   Epididymis

   
   -1.2.3.4.

   Ductus deferens

   
   -1.2.3.4.

   Spongy urethra

Question 6

1. Similarly to what we did with the female reproductive system, match the appropriate functional description to each structure.

   -A.B.C.D. Epididymis -A.B.C.D. Prostatic urethra -A.B.C.D. Spongy urethra -A.B.C.D. Ductus deferens

   A. Tube which carries sperm from the s crotum to the urethra B. Storage and maturation of sperm C. Surrounded by erectile tissue which enable copulation and deposition of sperm into the v agina D. Location where prostatic fluid is added to sperm

Answer 1

Question 2:

Now – think about the gametes that are produced within both the male and female reproductive systems. Which of the following statements is incorrect?

		Male gametes are produced in the testes, female gametes are produced in the ovaries --> TRUE
		Sperm reach final maturation and are stored within the epididymis --> TRUE
		Ova don’t complete their final stage of meiosis until fertilized by sperm --> TRUE
		Both spermatogonia and oogonia produce four mature gametes for each precursor cell following maturation --> FALSE

The primary spermatocyte undergoes two meiotic divisions (meiosis I and II) to produce a matured sperm, which have haploid number of chromosomes. Each spermatocyte produces four spermatids, in all of them, the chromosome number is reduced to half.

The cytoplasmic division of the secondary oocyte results in the formation of an egg (one egg) or ovum and three polar body, both are haploid (having “n” numbers of chromosomes). The polar body degrades itself, and is not capable of being fertilized.
