Question 1

Which of the following statements are true of the male reproductive glands and penis? (Read carefully and select all of the correct statements.)

Accepted Answer

A) The bulbourethral gland secretes a clear alkaline mucus that lines the urethra just before ejaculation to neutralize any acidic urine that may still be present and lubricate the urethra. 
B) Erection is the result of vasodilation brought about by parasympathetic impulses that increase blood flow to the penis, resulting in its engorgement with blood, causing it to become erect. 
C) The longest part of the urethra is within the penis, not the prostate gland. 
D) The seminal vesicles secrete fructose as nourishment for sperm, not glycogen. 
E) The prostate gland contributes to ejaculation, but it is smooth muscle, not striated muscle, and it is a sympathetic response, not a parasympathetic response. 
F) The secretions of the seminal vesicles contain fructose and prostaglandins and contribute to the alkalinity of seminal fluid.

Question 2

Which of the following statements are true of the reproductive hormones? (Read carefully and select all of the correct statements.)

Accepted Answer

B) In women, LH stimulates the release of a mature ovum from an ovarian follicle.
C) In women, both FSH and estrogen contribute to the growth and maturation of an ovarian follicle.
F) In men, both FSH and testosterone contribute to the growth and maturation of sperm.

A is incorrect because LH stimulates testosterone production in men, not meiosis. 
D is incorrect because inhibin inhibits the secretion of FSH, not testosterone or estrogen. 
E is incorrect because the secretion of progesterone is stimulated by LH, not FSH.

Question 3

Which statement is NOT true of spermatogenesis?

Accepted Answer

Spermatogenesis begins at puberty but does not end around the age of 50 to 60; instead, it typically continues throughout a man's life, although the quality and quantity of sperm may decrease with age.

Question 4

Which of the following statements are true of the vagina and vulva? (Read carefully and select all of the correct statements.)

Accepted Answer

A) The vagina is indeed the birth canal.
B) The labia majora and minora do cover the urethral and vaginal openings and help prevent drying of their mucous membranes.
C) The clitoris is a sensory organ for sexual arousal. 
D) This statement is incorrect. The secretion of Bartholin's glands lubricates the vaginal opening during sexual arousal, but it does not facilitate movement of an ovum.

Question 5

Which statement is NOT true of oogenesis?

Accepted Answer

Only one functional egg cell is produced for each cell that undergoes meiosis during oogenesis. The other product of meiosis is a polar body, which does not develop into an egg cell.

Question 6

Which of the following statements are true of the uterus? (Read carefully and select all of the correct statements.)

Accepted Answer

The answer of Which of the following statements are true...

Question 7

Which of the following statements are true of spermatogenesis or oogenesis? (Read carefully and select all of the correct statements.)

Accepted Answer

Spermatogenesis produces four haploid sperm cells per meiosis cycle. Oogenesis is cyclical, occurring monthly, while spermatogenesis is continuous. Both ovaries and testes have stem cells that give rise to gametes.

Question 8

For men,the hormone that initiates sperm production is:

Accepted Answer

The hormone that initiates sperm production in men is follicle-stimulating hormone (FSH), which is secreted by the anterior pituitary gland. Testosterone also plays a crucial role in the development and maintenance of male sexual characteristics, but it does not directly trigger sperm production. LH (luteinizing hormone) stimulates testosterone production in the testes, while inhibin regulates FSH production.

Question 9

The polar bodies produced by oogenesis:

Accepted Answer

The answer of The polar bodies produced by oogenesis:
...

Question 10

For men,the hormone that stimulates secretion of testosterone is:

Accepted Answer

The hormone that stimulates secretion of testosterone is LH (luteinizing hormone), which is produced by the pituitary gland. FSH (follicle-stimulating hormone) is involved in the development of sperm cells but does not directly stimulate testosterone production. GnRH (gonadotropin-releasing hormone) stimulates the pituitary to release LH and FSH. Inhibin is a hormone that inhibits the secretion of FSH but does not directly stimulate testosterone production.

Question 11

Which of the following statements are true of the ovaries and fallopian tubes? (Read carefully and select all of the correct statements.)

Accepted Answer

A) The cilia in the fallopian tubes help move the ovum toward the uterus. B) An ovum begins meiosis in an ovarian follicle. E) Fertilization typically occurs in the fallopian tube. F) After releasing an ovum, the follicle becomes the corpus luteum, a temporary endocrine gland.

Question 12

Which of the following statements are true of the menstrual cycle? (Read carefully and select all of the correct statements.)

Accepted Answer

The answer of Which of the following statements are true...

Question 13

Which statement is NOT true of spermatogenesis and oogenesis?

Accepted Answer

Spermatogenesis is a continuous process that starts at puberty and goes on throughout a male's life, producing millions of sperm daily. Oogenesis, on the other hand, is not cyclical in the same way; it involves the maturation of a single oocyte per cycle and is subject to a finite number of cycles that can occur within a female's reproductive lifespan.

Question 14

For men,the hormone that decreases the secretion of FSH is:

Accepted Answer

Inhibin is a hormone that is secreted by the testes in males and by the ovaries in females. It plays a role in regulating the secretion of follicle-stimulating hormone (FSH) from the pituitary gland. In males, inhibin is primarily responsible for decreasing the production and secretion of FSH.

Question 15

Which of the following statements are true of sperm? (Read carefully and select all of the correct statements.)

Accepted Answer

C) The acrosome is a structure located at the tip of the sperm that contains enzymes to help the sperm penetrate the outer membrane of the egg during fertilization.
D) On average, a healthy male will produce about 2-5mL of semen per ejaculation, and there can be millions of sperm cells within each milliliter.

Question 16

Spermatogenesis takes place in the ____ and produces ____ for every cell that undergoes the process.

Accepted Answer

The answer of Spermatogenesis takes place in the ____ and...

Question 17

Which of the following statements are true of the mammary glands? (Read carefully and select all of the correct statements.)

Accepted Answer

The answer of Which of the following statements are true...

Question 18

Oogenesis takes place in the ____ and produces ____ for each cell that undergoes the process.

Accepted Answer

Oogenesis takes place in the ovaries and produces one egg cell for each cell that undergoes the process.

Question 19

For men,the hormone that promotes maturation of sperm is:

Accepted Answer

The answer of For men,the hormone that promotes maturation of...
