chapters 28 and 26 but don't ask which ones are which



Ch. 28: (any missing numbers are missing because they're repeat questions.)
24. Which of the following glands are responsible for 60% of the synthesis of semen?
The seminal vesicles
25. Which of the following hormoes controls the release of anterior pituitary gonadotropins?
GnRH
26. The primary function of the uterus is to"
Receive, retain, and nourish a fertilized ovum
27. The corpus luteum is:
The ruptured follicle following the ejection of an oocyte from the ovary.
28. The structures that receive the ovulated oocyte, providing the site for fertilization, are called:
The fallopian tubes
29. Which of the following constitutes the female counterpart of the male scrotum?
The labia majora
30. Which of the following statements is true concerning the mammary glands of both males and females?
The mammary glands are modified sweat glands that are actually part of the integumentary system.
31. The female zygote receives chromosomes from:
Both the mother and father.
32. Human egg and sperm are similar in that:
They have the same number of chromosomes.
33. The constancy of chromosome numbers from one generation to the next is maintained through:
Meiosis
34. Fertilization generally occurs in the:
Fallopian tubes
35. Spermiogenesis involves:
The formation of a functional sperm by the stripping away of superfluous cytoplasm
36. A mechanical device inserted into the uterus as a means of birth control is the:
IUD
37. Effects of estrogen include:
Growth of the breasts at puberty
38. Secretion of progesterone stimulates:
Preparation of the mammary glands for lactation
39. Which of the following statements about the female reproductive process is not true?
Rebuilding the endometrium is under the control of prolactin
40. Normally menstruation occurs when:
Blood levels of estrogen and progesterone increase
41. The basic difference between spermatogenesis and oogenesis is that:
In oogenesis, one mature ovum is produced, and in spermatogenesis, four mature sperm are produced.
42. The cells that produce testosterone in the testis are called:
Interstitial cells or Leydig cells
43. Which of the following occurs as a result of undescended testes?
Inadequate or nonviable sperm are produced.
44. Which of the following occurs after ovulation?
All of the above.
45. All of the following statements referring to the uterine cycle are true except:
FSH and LH directly promote development of the uterine endometrium
46. Which of the following phases or processes in the monthly reproductive cycle of the female reproductive system occur simultaneously?
Regression of the corpus luteum and a decrease in ovarian progesterone secretion
47. Which is not a part of the proliferate phase of the female menstrual cycle?
Corpus luteum
48. Which of the following is a correct statement about uterine tubes?
The infundibulum is the funnel-shaped region near the ovary
49. Select the correct statement about the hormonal events of the ovarian cycle.
Rising levels of estrogen start follicle development.
50. Select the correct statement about the uterine cycle.
If fertilization occurs, the corpus luteum is maintained by a hormone secreted by the developing embryo.
16. The dartos and cremaster muscles are important to the integrity of the male reproductive system. Which of the following is true about the role that they play?
They regulate the temperature of the testes.
17. What mechanism divides the testes into lobules?
Septal extensions of the tricoalginea (sorry, I have no idea what I wrote but it starts with trico and ends in ginea)
18. The ability of sperm cells to move along the ductus deferens is due to:
Gravity
19. The most important risk for testicular cancer in young males is:
A diet high in fat
22. Development of male reproductive structures depends on which of the following events?
Secretion of male hormones prenatally and lasting into the first few months after birth.
25. Meiosis:
Produces haploid cells from diploid cells
27. All of the following can be considered male secondary sex characteristics except the:
Development of testes as opposed to ovaries.
28. Which of the following statements about spermatogeneis is true:
Each spermatid forms two sperm cells
29. Characteristics of the mature sperm include:
All of the above are correct
32. The testicular cells that construct the blood-testis barrier are the:
Sustentacular cells
33. The duct system of the male reproductive system includes:
The ductus deferens, a duct that runs from the testis up into the pelvic cavity.
34. The seminal vesicles:
Produce a yellowish fluid rich in fructose.
35. Spermatogenesis:
Involves a kind of cell division limited to the gametes.

Ch. 26
24. Which of the following regions of the nephron is most likely to be found in the renal medulla?
Loop of Henle
25. The filtration ne (can't read) includes all but:
Renal fascia
26. The mechanism of water reabsorption by the renal tubules is:
Osmosis
27. Most electrolyte reabsorption by the renal tubules:
Is hormonally controlled in distal tubule segments.
28. Apparently I skipped it :( Sorry!
29. Urine goes through the:
Pelvis of the kidney to ureter to bladder to urethra
30. A Bowman's capsule doe snot contain:
A vasca recta
31. An increase in the permeability of the cells of the collecting tubule to water is due to:
An increase in the production of ADH
32. The fluid in the glomerular and Bowman's capsule is similar to plasma except that it does not contain a significant amount of:
Plasma protein
33. Alcohol acts as a diuretic because: It inhibits the release of ADH
34. An important characteristic of urine is its specific gravity, or density, which is:
1.001-1.035
35. Which gland sists atop each kidney?
Adrenal
36. Place the following in the correct sequence from the dormation of a drop of urine to its elimination from the body:
3, 6, 2, 1, 5, 4
37. Select the correct statements about the nephron:
The parietal layer of the glomerular capsule is simple squamous epithelium
38. The glomurulus differs from other capillaries in the body in that it:
Is drained by an afferent arteriole.
39. Tubular reabsorption:
Involves movement against an electrical and/or chemical gradient.
40. The fatty tissue surrounding the kidnets is important because:
It stabilizes the position of the kidneys by holding them in their normal position.
41. The disruption in homeostasis known as pyelitsis is:
An infection of the renal pelis and calyces.
42. Reabsorption of high levels of glucose and amino acids in the filtrate is accomplished by:
Active transport
43. The functional unit of the kidney is:
The nephron
44. While the kidneys process about 180 L. of blood-derived fluids daily, the amount that actually leaves the body is 1% or 1.5 L

Glomerular hydrostatic pressure (glomerular blood pressure)


Happy studying!
