Front 3

Projections of the tunica albuginea, known as septae, divide the testis into

Back 3

lobules

Front 4

The spermatic cord is:

Back 4

a bundle of tissue that contains the ductus deferens and the blood vessels, nerves, and lymphatics that serve the testis

Front 5

The dense layer of connective tissue that surrounds the testis is called the

Back 5

tunica albuginea

Front 6

Interstatial cells produce

Back 6

testosterone

Front 7

The sustenacular cells of the seminiferous tubules do all of the following except

a. maintain the blood-testis barrier
b. support spermatogenesis
c. secrete inhibin
d. secrete testosterone

Back 7

d. secrete testosterone

Front 8

Sperm production occurs in the

Back 8

seminiferous tubules

Front 9

Sperm develop from stem cells called

Back 9

spermatagonia

Front 10

The process of spermatogenesis produces

Back 10

spermatozoa

Front 11

Sperm are moved along the ductus deferens by

Back 11

peristaltic contractions

Front 12

The structure that carries sperm from the epididymis to the urethra is the

Back 12

ductus deferens

Front 13

The secretory structure that produces a secretion that contains fructose, prostaglandins, and fibrinogen is the

Back 13

seminal vesicle

Front 14

The structure that surrounds the urethra and produces a secretion that is slightly acidic is the

Back 14

prostate gland

Front 15

The small paired structures at the base of the penis that produce a lubricating secretion are the

Back 15

bulbourethral glands

Front 16

Semen contains all of the following except

a. spermatozoa
b. seminal fluid
c. prostaglandins
d. spermatids

Back 16

d. spermatids

Front 17

The fold of skin that covers the glans penis is the

Back 17

prepus

Front 18

The erectile tissue that is located on the anterior surface of the flaccid penis is the

Back 18

corpus cavernosum

Front 19

Functions of testosterone include all of the following except

a. initiation of puberty
b. determining secondary sex characteristics
c. stimulating sexual behavior and sex drive
d. promoting the functional maturation of sperm

Back 19

a. initiation of puberty

Front 20

The pituitary hormone that stimulates the interstitial cells to secrete testosterone is

Back 20

LH

Front 21

The structure that transports the ovum to the uterus is the

Back 21

uterine tube

Front 22

The organ that provides mechanical protection and nutritional support for the developing embryo is the

Back 22

uterus

Front 23

The inferior portion of the uterus that projects into the vagina is the

Back 23

cervix

Front 24

The muscular layer of the uterus is the

Back 24

myometrium

Front 25

Each of the following statements concerning oogenesis is true except one. Identify the exception.

a. At the time of birth the ovaries contain only primary oocytes.
b. The first meiotic division is completed just prior to ovulation.
c. An ovum will only complete meiosis if it is fertilized.
d. Oogenesis occurs continuously from puberty until menopause.

Back 25

d. Oogenesis occurs continuously from puberty until menopause.

Front 26

The surge in LH that occurs during the middle of the ovarian cycle triggers

Back 26

ovulation

Front 27

A rise in the blood levels of FSH at the beginning of the ovarian cycle is responsible for

Back 27

follicle maturation

Front 28

The average length of the menstrual cycle is

Back 28

28 days

Front 29

During the proliferative phase of the menstrual cycle

Back 29

a new functional layer is formed in the uterus

Front 30

During the menses

Back 30

the old functional layer is sloughed off

Front 31

All of the following are true of the vagina except that it

a. serves as a passageway for the elimination of menstrual fluids
b. receives the penis during sexual intercourse
c. forms the lower portion of the birth canal
d. loses a portion of its lining during menstrual flow

Back 31

d. loses a portion of its lining during menstrual flow

Front 32

The vulva includes all of the following except the

a. mons pubis
b. labia majora
c. clitoris
d. cervix

Back 32

d. cervix

Front 33

The central space bounded by the labia minora is the

Back 33

vestibule

Front 34

The clitoris is

Back 34

a mass of erectile tissue located at the anterior margin of the labia majora

Front 35

The principal hormone secreted by the corpus luteum is

Back 35

progesterone

Front 36

Menstruation is triggered by a drop in the levels of

Back 36

estrogen and progesterone

Front 37

The developing follicle cells secrete

Back 37

estrogens

Front 38

Contractions of the ischiocavernosus and bulbocavernosus muscles result in

Back 38

ejaculation

Front 39

Contraction of the cremaster muscle

Back 39

move the testis closer to the body

Front 40

Sally is an avid jogger and she trains incessantly. She has slimmed down so that she is now underweight for height and has very little fat tissue. You would expect Sally to
