thick layer of smooth muscle cells

Which region of the uterine tube captures the ovum?

infundibulum

Which of the following is not an action of estrogen?

A. initiates repair of the endometrium

B. maintains female secondary sex characteristics

C. maintains accessory reproductive organs

D. mimics the symptoms of menopause

E. stimulates bone growth

D. mimics the symptoms of menopause

The granulosa cells of developing follicles secrete

estradiol.

Menstruation is triggered by a drop in the levels of

progesterone.

During the menses,

the old functional layer is sloughed off.

The uterine phase that develops because of a fall in progesterone levels is the

menses.

The inferior one-third portion of the uterus that projects into the vagina is the

cervix.

During the secretory phase of the menstrual cycle,

A. the fertilized ovum implants.

B. All of the answers are correct.

C. progesterone levels are high.

D. endometrial glands enlarge.

E. the corpus luteum is formed.

B. All of the answers are correct.

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

ovulation.

During the proliferative phase of the menstrual cycle, the

functional zone of the endometrium is restored.

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

uterus.

The organ that transports the ovum to the uterus is the

uterine (Fallopian) tube.

A. All of the answers are correct.

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

LH.

The PSA test is used for diagnosis of

prostate cancer.

Spermatozoa are functionally matured within the

epididymis.

meiosis.

initiate sperm production in the testes.

The paired erectile bodies in the penis are the

corpora cavernosa.

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

seminal gland (seminal vesicle).

The erectile tissue that surrounds the urethra is the

E. spermatogonia.

The small paired structures at the base of the penis that secrete a thick, alkaline mucus are the

bulbo-urethral glands.

The organ that surrounds the urethra and produces an alkaline secretion is the

prostate gland.

When spermatogonia divide, the daughter cells are called

spermatocytes.
