Question 1

The ________ of the sperm cell is a membranous compartment that contains enzymes essential to fertilization of an egg.&#10;A) acrosome&#10;B) head&#10;C) middle piece&#10;D) neck

Accepted Answer

The acrosome is a membranous compartment located at the head of the sperm cell that contains enzymes essential for fertilization of an egg. The other options, such as the head, middle piece, and neck of the sperm cell, do not contain enzymes essential to fertilization.

Question 2

The ________ both transports urine outside the body during urination and transports semen to the female reproductive tract during intercourse.&#10;A) penis&#10;B) ureter&#10;C) ductus deferens&#10;D) epididymis

Accepted Answer

The penis is the correct answer as it is responsible for both transporting urine out of the body during urination and transporting semen to the female reproductive tract during intercourse. The ureter is responsible for carrying urine from the kidneys to the bladder, the ductus deferens carries sperm from the epididymis to the urethra, and the epididymis stores and matures sperm.

Question 3

The regions of the penis are ________.&#10;A) the body and the glans&#10;B) the root and the glans&#10;C) the root and the body&#10;D) the root, the body, and the glans

Accepted Answer

The penis has three regions: the root, the body, and the glans. The root is the base of the penis that attaches to the pelvic bone, the body is the middle section, and the glans is the rounded tip.

Question 4

________ results in the production of spermatozoa.&#10;A) Spermatogenesis&#10;B) Ejaculation&#10;C) Urination&#10;D) Erection

Accepted Answer

Spermatogenesis is the process by which spermatozoa are produced in the testes. Ejaculation is the process of expelling semen from the penis, but it does not produce sperm. Urination is the process of expelling urine from the bladder, which is unrelated to sperm production. Erection is the process of enlarging and stiffening the penis, but it does not produce sperm.

Question 5

The male reproductive system is responsible for ________.&#10;A) the production of sex hormones&#10;B) the production of sex hormones, the production and storage of sperm, and transportation of sperm to the female reproductive tract during intercourse&#10;C) the production of sex hormones as well as the production and storage of sperm&#10;D) the production and storage of sperm as well as transportation of sperm to the female reproductive tract during intercourse

Accepted Answer

The male reproductive system is responsible for the production of sex hormones, the production and storage of sperm, and transportation of sperm to the female reproductive tract during intercourse. Choice A is incorrect because it only mentions the production of sex hormones. Choice C is partially correct but does not include the transportation of sperm, which is crucial for fertilization. Choice D is also partially correct but lacks the mention of sex hormone production.

Question 6

The ________ of the seminiferous tubules nourish the spermatogenic cells and regulate spermatogenesis.&#10;A) lobules&#10;B) stereocilia&#10;C) nurse cells&#10;D) interstitial cells

Accepted Answer

Nurse cells (also called Sertoli cells) are located within the seminiferous tubules and provide nourishment to the developing sperm cells. They also help regulate spermatogenesis by producing hormones and providing structural support for developing sperm cells. Lobules are the functional units of the testes, stereocilia are part of the epididymis, and interstitial cells (also called Leydig cells) produce testosterone but do not directly regulate spermatogenesis.

Question 7

Spermatozoa become functionally mature in the ________.&#10;A) urethra&#10;B) ejaculatory duct&#10;C) epididymis&#10;D) ductus deferens

Accepted Answer

Spermatozoa become functionally mature in the epididymis, where they gain the ability to propel themselves forward and fertilize the female egg. The urethra, ejaculatory duct, and ductus deferens serve as transport tubes for the sperm but do not contribute to their functional maturation.

Question 8

The ________ produces sperm and hormones.&#10;A) epididymis&#10;B) testis&#10;C) urethra&#10;D) scrotum

Accepted Answer

The testis is responsible for producing both sperm and hormones, specifically testosterone. The epididymis is where the sperm mature and are stored before ejaculation, the urethra is the tube that carries urine and semen out of the body, and the scrotum is the sac that holds the testes.

Question 9

The columns of erectile tissue in the penis include ________.&#10;A) one corpus cavernosum and one corpus spongiosum&#10;B) two corpora cavernosa and one corpus spongiosum&#10;C) one corpus cavernosum and two corpora spongiosa&#10;D) three corpora cavernosa

Accepted Answer

The correct option is two corpora cavernosa and one corpus spongiosum. The corpora cavernosa are cylindrical structures of erectile tissue that fill with blood during an erection, and there are two of them in the penis. The corpus spongiosum is a smaller column of tissue that surrounds the urethra and also becomes engorged with blood during an erection.

Question 10

Secretions of the bulbourethral (Cowper's)gland ________.&#10;A) contain fluid and enzymes&#10;B) promote the growth of bacteria near the prepuce&#10;C) lubricate the tip of the penis&#10;D) contribute to the volume of semen

Accepted Answer

The bulbourethral glands secrete a clear fluid that lubricates the tip of the penis.
