ejaculatory duct

Arrange the following structures in the order sperm would pass through them from the seminiferous tubules to the urethra

ductus deferens

efferent ductules

epididymis

ejaculatory duct

rete testis

The ductus deferens

passes through the inguinal canal and enters the pelvic cavity

extends through the length of the penis

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

urethra

The longest portion of the male urethra is the

spongy urethra

The penis consists of _____ columns of erectile tissue

three

Which of the following is mismatched

prepuce - skin that covers the glans penis - correct

corpora cavernosa - does NOT form the foreskin

Circumcision

the removal of the prepuce

Erection of the penis occurs when

penile erectile tissue becomes engorged with blood

The spongy urethera is surrounded by the c

corpus spongiosum

Which of the following statements is FALSE

the seminal vesicles open into the membranous urethra is FALSE

the seminal vesicles DO open into the membranous urethra

The accessory glands near the membranous uretrha are

bulbourethral glands

Semen is

sperm cells plus the secretions of accessory glands

Most of the seminal fluid is produced

by the seminal vesciles

Discharge of semen into the prostatic urethra is called

erection

Which of the following glands is correctly matched with its function

seminal vesicles provide nutrients for sperm

Given the following glands, choose the arrangement that represents the order in which the glands release their secretions to form semen

prostate gland

bulbourethral gland

seminal vesicles

Which of the following substances found in semen is mismatched with its function

prostaglandins - cause urethral contractions

Which of the following substances are found in the secretions of the prostate gland

fibrinolysin and clotting factors

The secretions produced by the prostate gland

constitute about 30% of the semen

A blood test for the prostate-specific antigen (PSA) is useful in the diagnosis of

prostatic cancer

A pituitary tumor interferes with FSH secretion. How would this affect a male

He would not produce sperm

LH (lutenizing hormone) binds to interstitial cells and

increases testosterone production by the interstitial cells

A lack of testosterone production before birth would

inhibit normal development of male reproductive structures

Once GnRH is released from the hypothalamus and enters the hypothalamophophysial portal system

FSH and LH secretion will occur

Which of the following hormones stimulates the synthesis of testosterone by the fetal testes

Human chorionic gonaotropin (hCG)

What is the active hormone in target tissues of testosterone such as the penis

Dihydrotestosterone

The major factor controlling the onset of puberty in males is

the hypothalamus becoming less sensitive to the inhibitory effects of androgens

Testosterone

can lead to an increase in muscle mass

Which of the following effects canNOT be attributed to testosterone

increased calcium excretion

Which hormone would decrease if an adult male were castrated

testosterone would decrease

Following ejaculation, a phase called resolution occurs. During resolution-

a feeling of satisfaction occurs

Erection and ejaculation can be initiated by

manual stimulation of the penis

Which of the following events occurs in an erection

engorgement of erectile tissue of penis with blood

Impotence occurs when

an erection cannot be achieved or maintained

The following events are in the correct sequence

erection, emission, ejaculation

The following events are in the correct sequence

arteries supplying blood to erectile tissue dilate

blood fills erectile tissue sinusoids and compresses veins

inflation and rigidity of erectile tissue

Which of the following events in the male sex act occurs last and results in ejaculation

contractions of skeletal muscle at the base of the penis

What is the role of NO (nitric oxide) in the male sex act?

Dilation of blood vessels in the penis

The ovaries and uterus are held in position within the pelvis by band of tissue called

ligaments

The ovary is attached to the superior margin of the uterus by the

ovarian ligament

The ovary is surrounded by a capsule of fibrous connective tissue called the

tunica albuginea

Of the 2 million primary oocytes in the ovaries at birth, only about _____ are ovulated

400

A primary oocyte with a single layer of granulosa cells is most appropriately called

a primordial follicle

A primary follicle contains

several layers of granulosa cells

As a secondary follicle enlarges

a theca or capsule is formed around it

In a mature follicle, the oocyte lies in a mass of follicular cells called

the cumulus mass

A follicle contianing a secondary oocyte and a single fluid-filled antrum is called a

mature follicle

The release of the secondary oocyte from the ovary is called

ovulation

Which of the following is produced from the ovary and then leaves the ovary

the secondary oocyte

The secondary oocyte completes the second meiotic division when

it is penetrated by a sperm cell

Fertilization occurs when the

nuclei of the secondary oocyte and sperm cell unite

Zygote is a term used to describe

a fertilized oocyte

Follicles in the ovary that are not ovulated

undergo atresia

The corpus luteum is a gland that

forms from a mature follicle after ovulation and secretes mainly progesterone

Assume a couple has just completed intercourse and sperm have been deposited in the woman's reproductive tract. Trace the pathway of the sperm through the female reproductive tract to the point where fertilization will most likely occur

vagina, cervix, cavity of uterus, fallopian tubes

The tunica albuginea

dense fibrous connective tissue covering

Cortex

dense outer portion of the ovary proper

Antrum

a chamber within the mature follicle

Cumulus mass

follicular cells located on one side of the mature follicle

Corona radiata

the innermost cells of the cumulus mass

What is the last follicular stage

corpus albicans

Which statement concerning the uterus is true

the inferior portion is called the cervix

A pap test is used to detect

cervical cancer

The cervix is a portion of the

uterus

Which of the following statements is true conceding the uterine tube

the oocyte is moved along the tube by peristaltic contractions of the muscular layer.

The layer of the uterine wall that is shed during menustration is the

endometrium

Which of the following pairs is correctly matched

the broad ligaments DO help support the uterus

Which of the following is a function of the vagina
