Chapter 12

Question 1

Scrotum, testes, epididymides, penis, and urethra.

Answer 1

external genitalia

Question 2

Male internal and external genitalia.

Answer 2

genital organs

Question 3

Two body systems (male reproductive system, urinary system) that share some structures.

Answer 3

genitourinary system

Question 4

vans deferens, seminal vesicles, ejaculatory ducts, prostate gland, and bulbourethral glands in the pelvic cavity.

Answer 4

internal genitalia

Question 5

Long, coiled tube on the outer wall of each testis. It receives spermatozoa from the seminiferous tubules, adds a cap-like layer of enzymes to them, and destroys defective spermatozoa.

Answer 5

epididymis

Question 6

The male sex glands (ie the testes).

Answer 6

gonads

Question 7

Passageway through the abdominal muscles, over the pubic bone, and through the groin area through which the testes travel before birth as they descend from the pelvic cavity to the scrotum.

Answer 7

inguinal canal

Question 8

Cells between the seminiferous tubules of the testes. They secrete testosterone when stimulated by luteinizing hormone.

Answer 8

interstitial cells

Question 9

Central open area throughout the length of a tube or duct (such as the seminiferous tubule, vans deferens, ejaculatory duct, or urethra).

Answer 9

lumen

Question 10

Area on the outside of the body between the anus and the scrotum.

Answer 10

perineum

Question 11

Pouch of skin behind the penis that holds the two testes.

Answer 11

scrotum

Question 12

Tubules within each testis that produce spermatozoa.

Answer 12

seminiferous tubules

Question 13

Tube that, before birth, contains arteries, veins, and nerves for each testis as well as the vas deferens. It passes through the inguinal canal.

Answer 13

spermatic cord

Question 14

An individual mature sperm.

Answer 14

spermatozoon

Question 15

Egg-shaped gland in each side of the scrotum.

Answer 15

testes

Question 16

Most abundant and most biologically active of the male sex hormones secreted by the interstitial cells of the testes. It causes the male sexual characteristics to develop and spermatozoa to mature.

Answer 16

testosterone

Question 17

During sexual arousal, erectile tissue in the penis fills with blood, causing the penis to become firm and erect.

Answer 17

erection

Question 18

Organ of erectile tissue that fills with blood during male sexual arousal.

Answer 18

penis

Question 19

The rounded area on top of the shaft of the penis.

Answer 19

glans penis

Question 20

Two columns of tissue along the upper surface of the penis.

Answer 20

corpora cavernosa

Question 21

A column of tissue on the underside of the penis.

Answer 21

corpus spongiosum

Question 22

Foreskin of the penis that covers the urethral meatus in an uncircumcised male.

Answer 22

prepuce

Question 23

Small, bulb-like glands at the base of the penis that produce mucus that becomes part of the semen.

Answer 23

bulbourethral glands

Question 24

Duct that collects spermatozoa from the vas deferens and fluid from the seminal vesicles and empties into the urethra during ejaculation.

Answer 24

ejaculatory duct

Question 25

Donut-shaped gland at the base of the bladder.

Answer 25

prostate gland

Question 26

Fluid expelled from the penis during ejaculation.

Answer 26

semen

Question 27

Glands along the posterior wall of the bladder that secrete seminal fluid, a source of energy for the spermatozoa and main fluid of semen.

Answer 27

seminal vesicles

Question 28

Long tube that receives spermatozoa from the epididymis and carries them to the seminal vesicles.

Answer 28

vas deferens

Question 29

The physical union of two people during sexual intercourse.

Answer 29

coitus

Question 30

Sudden expelling of semen from the penis during sexual arousal of the male.

Answer 30

ejaculation

Question 31

Hormone secreted by the anterior pituitary gland. It causes the seminiferous tubules of the testes to enlarge during puberty and spermatocytes in the testes to begin dividing.

Answer 31

follicle-stimulating hormone (FSH)

Question 32

A cell (male spermatozoon or female ovum) that has 23 chromosomes instead of the usual 46 chromosomes like other cells.

Answer 32

gamete

Question 33

Hormone secreted by the anterior pituitary gland. It causes the interstitial cells of the testes to begin secreting testosterone during puberty.

Answer 33

luteinizing hormone (LH)

Question 34

Process by which a spermatocyte reduces the number of chromosomes in its nucleus to 23, or half the normal number, to create gametes.

Answer 34

meiosis

Question 35

Process by which most body cells reproduce. The 46 chromosomes in the nucleus duplicate, and then split, creating two identical cells, each with 46 chromosomes.

Answer 35

mitosis

Question 36

Period of time when FSH and LH from the anterior pituitary gland first begin to stimulate the testes. Testosterone causes the male sexual characteristics to develop, and there is a growth spurt.

Answer 36

puberty

Question 37

Immature spermatozoon in the wall of the seminiferous tubule during childhood.

Answer 37

spermatocyte

Question 38

Process of producing a mature spermatozoon through the processes of mitosis and meiosis.
