HB 11 D406 Reproduction Revision R Questions 25 October 2004

Give the most suitable human biology term for each of the following.

1. Cells which produce testosterone which is responsible for the secondary sexual characteristics of the male. [222-3]

2. The pair of pouch-like organs (located behind the urinary bladder) that secrete a thick fluid which (is rich in sugars and) becomes part of the semen. [223]

3. The highly folded tubule that fits against the rear surface of each testis and acts as a storage location for sperm while they mature. [223]

4. The primary sex organs of the female which produce and release ova. [223]

5. The structures which are lined with cells that divide by meiosis to produce sperm. [222]

6. In males, it sometimes transports urine, and at other times it transports sperm. [223]

7. The single, hollow, pear-shaped organ which is specialised for foetal development. [225]

8. The structure which extends from near the ovary to the uterus, is the site of fertilisation. [224]

9. The single gland (where the two vasa deferentia join the urethra) which secretes a thin, milky, alkaline fluid that becomes part of the semen. [223]

10. At the lower end of the uterus is the neck of the uterus. [225]

11. The structure which carries the sperm away from the testis, being the continuation of the tubule of the epididymis. [223]

12. Two small yellow glands each about the size of a pea (located beneath the prostate on either side of the urethra) which secrete a clear mucus that acts as a lubricant. [223]

2. Fertilisation of the human ovum usually takes place in the

(a) uterine tube.
(b) uterus.
(c) cervix
(d) vagina. [   ]

3. There are many similarities and differences between the production of sperm and the production of ova. Which of the following is a difference between the two processes?

(a) the number of divisions that occur.
(b) the number of gametes produced from each primary cell.
(c) the number of chromosomes in the gamete.
(d) the alignment of the chromosomes during metaphase. [   ]

4. Which one of the following sexually transmitted diseases reduces the body’s resistance to infection?

(a) syphilis
(b) gonorrhoea
(c) herpes
(d) AIDS [   ]

5. LH stimulates the interstitial cells of the testes to:

(a) degenerate.
(b) produce sperm
(c) secrete testosterone
(d) secrete oestrogen. [   ]

6. The vagina is usually kept clean and free from infection by:

(a) acidic mucus fom the wall of the vagina.
(b) loss of blood during menstruation.
(c) action of acidic mucus from the cervix.
(d) oestrogen causing a change to the lining each month. [   ]

7. Ovulation is the process by which:

(a) sperms are ejected from the penis.
(b) an egg is ejected from the ovary.
(c) an egg implants on the wall of the uterus.
(d) an egg is produced and brought to maturity. [   ]

8. In its passage through the oviduct to the uterus, the fertilised egg:

(a) swims by itself.
(b) descends by gravity.
(c) is propelled by cilia.
(d) moves by contraction of the uterus. [   ]

9. The part of the testis that acts as an endocrine gland is/are the:

(a) seminiferous tubules.
(b) interstitial cells.
(c) epididymis.
(d) germinal epithelial cells. [   ]

10. If both sperm ducts are cut, then:

(a) sperm will be produced but there will be no seminal fluid.
(b) neither sperm nor male sex homone will be produced.
(c) sperm will not be able to be released, but male sex hormone will be.
(d) sperm will be produced, but male sex hormone will not be. [   ]

11. Identical twins have many similar characteristics because:

(a) the two eggs from which they developed contained exactly the same number of chromosomes.
(b) they were exposed to exactly the same environment during embryonic development.
(c) they are the same age and have the same parents.
(d) they occur as a result of division of a single zygote. [   ]

12. Follicle stimulating hormone is produced in the:

(b) the cycle occurs at a more rapid rate.
(c) menstruation does not occur.
(d) progesterone surround the embryo. [   ]

15. Gonorrhoea and syphilis differ from most diseases because:
