1.

Which of the following parts of the female mammary gland produces milk?

The areola

The alveoli

The ampulla

The adipose tissue

2.

Identify an accurate statement about the hormonal control of male reproduction.

Before birth, human chorionic gonadotropin secreted by the placenta inhibits the developing testes of the embryo from secreting testosterone.

Luteinizing hormone and follicle-stimulating hormone boost testosterone secretion after puberty in a major positive feedback loop.

The testes secrete the maximum amount of testosterone in the period between birth and puberty.

Puberty in males is characterized by a radical reduction in the amount of testosterone secreted by the testes.

Correct :

3.

Identify a difference between the luteal phase and the proliferative phase.

The time between the end of menses and ovulation is known as the proliferative phase, while the time between ovulation and menses is known as the luteal phase.

The corpus luteum develops in the ovary during the proliferative phase, while the follicles start maturating in the ovary during the luteal phase.

The luteal phase is also known as the follicular phase, while the proliferative phase is also known as the secretory phase.

The proliferative phase is characterized by the secretion of the hormone progesterone, while the luteal phase is characterized by the secretion of the hormone estrogen.

Correct :

5.

In the context of the female reproductive system, identify an accurate statement about the structure of the uterus.

The uterus is located anterior to the urinary bladder in the pelvic cavity.

The narrow, inferior portion of the uterus is called the isthmus.

The innermost layer of the uterus wall is known as the myometrium.

The lateral cervical ligaments help attach the uterus to the lateral pelvic walls of the pelvic cavity.

6.

Which of the following is a difference between the endometrium and the myometrium of the uterus wall?

The endometrium forms the outermost layer of the uterine wall, while the myometrium forms the innermost layer of the uterine wall.

The endometrium is composed of columnar epithelium and secretory cells, while the myometrium is primarily composed of smooth muscle.

The endometrium is never replaced, whereas the myometrium is shed and regenerated every 28 days.

The endometrium receives its blood supply from arcuate arteries, whereas the myometrium receives its blood supply from radial arteries.

The endometrium is composed of columnar epithelium and secretory cells, while the myometrium is composed of smooth muscle. The myometrium is the middle layer of the

7.

Which type of epithelium makes up the seminal vesicles?

Simple squamous epithelium

Simple cuboidal epithelium

Transitional epithelium

Psuedostratified epithelium

8.

In the context of the male reproductive system, identify an accurate statement about the testes.

The abnormal collection of fluid within the testes is termed cryptorchidism.

The testes migrate into the scrotum during the first three months of embryonic development.

Each testis is composed of 250 to 300 wedges called lobules.

The serous membrane that surrounds each testis is called the adventitia.

9.

Identify a similarity between the male reproductive system and the female reproductive system.

Both the male reproductive system and the female reproductive system have the same number of accessory genitalia.

In both the female reproductive system and the male reproductive system, the urethra acts both as a channel for excreting urine and releasing gametes.

In both the female reproductive system and the male reproductive system, the primary genitalia are external.

Both the female reproductive system and the male reproductive system have a pair of gonads.

10.

Which condition is most likely a result of the incessant proliferation, bleeding, and decay of endometrial tissue in the pelvic and abdominal cavities?

Endometrial carcinoma

Endometriosis

Polycystic ovarian syndrome

Vaginitis

11.

Identify an accurate statement about menstrual disorders.

When menstruation is difficult and involves painful cramping, it is known as dysmenorrhea.

Infection by staphylococcus aureus is the main cause of polycystic ovarian syndrome.

Premenstrual syndrome is typically characterized by symptoms associated with the proliferative phase of the menstrual cycle.

GnRH agonists are always administered to treat mild premenstrual syndrome.

12.

29-year-old Esma has been having irregular menstrual cycles. She and her husband have not been able to conceive a child. Suspecting that she may be infertile, Esma visits Dr. Grey for a medical check-up. On examination, Dr. Grey notes that Esma is overweight, has excess facial hair, and is showing signs of baldness. He also discovers that she is resistant to insulin and experiences hypertension. Imaging and blood tests reveal that Esma’s gonads are abnormally large and that she has increased blood levels of testosterone and estrogen, but very low levels of progesterone. What is the most probable diagnosis for Esma’s condition?

Toxic shock syndrome

Mastitis

Polycystic ovarian syndrome

Endometriosis

13.

What is the most common nonskin form of cancer that affects American men?

Breast cancer

Prostrate cancer

Brain cancer

Liver cancer

14.

Identify an accurate statement about erectile dysfunction.

Apomorphine is a drug that can help improve the symptoms of erectile dysfunction.

Erectile dysfunction is relatively common among men between the ages of 20 and 35.

Erectile dysfunction tends to decrease with age.

A person is usually diagnosed with erectile dysfunction if he is unable to maintain an erection over a period of one to two weeks.

15.

Mario, a 65-year-old Hispanic male, visits Dr. Lyra for a medical examination. He complains that he often feels the urge to urinate and that this urge often disrupts his sleep at night. He tells Dr. Lyra that his urine stream is weak and that he experiences the sensation of incomplete voiding whenever he urinates. Dr. Lyra conducts a thorough medical examination and instructs Mario to undergo some laboratory tests. The results of the tests rule out urinary conditions such as urinary tract infection, diabetes mellitus, and an overactive bladder. Lyra suspects that the enlargement of a certain gland surrounding Mario’s urethra might be causing these symptoms. Based on Dr. Lyra’s suspicions, from which condition is Mario most likely suffering?

Cryptorchidism

Hydrocele

Benign prostatic hyperplasia

Erectile dysfunction disorder

16.

Which type of medical imaging technique is based on the same principles as that of SONAR or fish finders in fishing boats?

X-ray

Magnetic resonance imaging

Computerized tomography

Ultrasound

17.

Which of the following statements is true about ultrasound?

Ultrasound imaging involves a high degree of radiation exposure.

Ultrasound imaging uses magnetic energy to produce cross-sectional images of structures within the body.

Ultrasound procedures often trigger feelings of claustrophobia in patients.

Ultrasound imaging is a lot more sensitive than a regular x-ray.

18.

Angelina is in her fourth month of pregnancy. Her obstetrician, Dr. Keller, uses a certain imaging technique to monitor the development of Angelina’s fetus. This technique does not involve any radiation exposure and allows Dr. Keller to view the movements of the fetus in real time.
