Question 1

Arrange the following structures in the order sperm would pass through them from the seminiferous tubules to the urethra. (1)ductus deferens (vas deferens)
(2)efferent ductules
(3)epididymis
(4)ejaculatory duct
(5)rete testis

Accepted Answer

Sperm travels from the seminiferous tubules to the rete testis (5), then through the efferent ductules (2), into the epididymis (3), through the ductus deferens (1), and finally through the ejaculatory duct (4) before reaching the urethra.

Question 2

The spongy urethra is surrounded by the

Accepted Answer

The spongy urethra is surrounded by the corpus spongiosum.

Question 3

Most of the seminal fluid is produced

Accepted Answer

The answer of Most of the seminal fluid is produced
...

Question 4

Which portion of the sperm cell is most involved with penetration of the female sex cell?

Accepted Answer

The acrosome is a structure on the head of the sperm cell that contains enzymes involved in penetrating the female sex cell, also known as the oocyte or egg.

Question 5

The duct from the seminal vesicle joins the ductus deferens to form the

Accepted Answer

The duct from the seminal vesicle joins the ductus deferens to form the ejaculatory duct, which is responsible for transporting semen from the seminal vesicles and the vas deferens to the prostatic portion of the urethra during ejaculation.

Question 6

The ductus deferens

Accepted Answer

The answer of The ductus deferens
...

Question 7

Sperm are produced in the _____ and complete maturation in the _____.

Accepted Answer

Sperm are produced in the seminiferous tubules of the testes and complete maturation in the epididymis. The epididymis is a tightly coiled tube located on the surface of each testis, and it stores and carries sperm from the testes to the vas deferens during ejaculation. The ductus deferens is a muscular tube that connects the epididymis to the prostate gland. The prostate gland secretes prostate fluid, which is a component of semen.

Question 8

A primary spermatocyte is a diploid cell that gives rise to two secondary spermatocytes after the first meiotic division.The primary spermatocyte has

Accepted Answer

A primary spermatocyte is a diploid cell, which means it has a full set of chromosomes (46 in humans). During the first meiotic division, it divides into two haploid cells called secondary spermatocytes, each with half the number of chromosomes (23 in humans). Therefore, the primary spermatocyte must have a total of 46 chromosomes.

Question 9

Circumcision is the surgical removal of the

Accepted Answer

Circumcision is the surgical removal of the prepuce, also known as the foreskin, which covers the glans penis. The crus penis, corpora cavernosa, and bulb of penis are not removed during circumcision. The glans penis is not usually removed during circumcision, although in some rare cases it may be partially removed due to medical reasons.

Question 10

Which of the following is mismatched?

Accepted Answer

Stereocilia are not involved in forming sperm tails, but are hair-like projections found in the epididymis and parts of the male reproductive tract. Sperm tails are formed by the flagellum, which is a structure composed of microtubules.

Question 11

Erection of the penis occurs when

Accepted Answer

Erection of the penis occurs when penile erectile tissue becomes engorged with blood. The blood vessels in the erectile tissue dilate, allowing more blood to flow into the tissue than out, which causes the penis to enlarge and become erect.

Question 12

Smooth muscle contractions help to propel sperm in the

Accepted Answer

Smooth muscle contractions in the ductus deferens help to propel sperm during ejaculation.

Question 13

The longest portion of the male urethra is the

Accepted Answer

The spongy urethra, also known as the penile urethra, is the longest portion of the male urethra, extending from the bulb of the penis to the external urethral orifice.

Question 14

The accessory glands located near the membranous urethra are the

Accepted Answer

The accessory glands located near the membranous urethra are the bulbourethral glands, also known as Cowper's glands. They secrete a clear, slippery fluid that lubricates the urethra and neutralizes any acidic urine that may be remaining in the urethra.

Question 15

Which of the following is mismatched?

Accepted Answer

Corpora cavernosa are erectile tissue that fill with blood during an erection, they do not form the foreskin.

Question 16

Semen is

Accepted Answer

Semen is a mixture of sperm cells and secretions from the accessory glands, such as the seminal vesicles, prostate gland, and bulbourethral gland. These secretions provide nutrients, protection, and mobility for the sperm.

Question 17

Which of the following statements is false?

Accepted Answer

The seminal vesicles do not open into the membranous urethra; they open into the ejaculatory ducts, which then pass through the prostate gland to join the prostatic urethra.

Question 18

The male urethra

Accepted Answer

The answer of The male urethra
...

Question 19

The penis consists of _____ columns of erectile tissue.

Accepted Answer

The penis consists of three columns of erectile tissue: two corpora cavernosa on the dorsal side and one corpus spongiosum on the ventral side.

Question 20

In males,both urine and male reproductive fluids travel through the

Accepted Answer

In males, both urine and male reproductive fluids (including semen) travel through the urethra. The ureter carries urine from the kidneys to the bladder. The epididymis, spermatic cord, and ductus deferens are all involved in the transport and storage of sperm during the male reproductive process, but they do not carry urine.
