Тест: Female Reproductive System Anatomy — 10 въпроса

1. What is the primary function of the fallopian tubes in the female reproductive system?

A. Production of estrogen and progesterone

B. Storage of mature ova

C. Support of the uterus during pregnancy

D. Transport of ova and site of fertilization

Answer: (D)

Обяснение

The fallopian tubes are responsible for transporting ova from the ovaries to the uterus and are the typical site of fertilization. They do not produce hormones, support the uterus, or store ova.

2. What is the primary blood supply to the uterus, and why is this clinically significant?

A. Ovarian artery, because it supplies only the ovaries

B. Uterine artery, because it crosses the ureter which is relevant during surgeries

C. Abdominal aorta directly, because it supplies all pelvic organs

D. Internal iliac artery, because it supplies the gluteal region

Answer: (B)

Обяснение

The uterine artery is the main blood supply to the uterus and crosses the ureter, an important detail (known as 'water under the bridge') to avoid during pelvic surgeries.

3. Which ligament is responsible for supporting the uterus anteriorly?

A. Uterosacral ligament

B. Round ligament

C. Cardinal ligament

D. Broad ligament

Answer: (B)

Обяснение

The round ligament supports the anterior aspect of the uterus, helping to maintain its position within the pelvis. The uterosacral ligament supports the posterior aspect, and the broad and cardinal ligaments have other supportive roles.

4. Where does fertilization of the ovum most commonly occur, and which part of the fallopian tube is involved?

A. In the infundibulum, near fimbriae

B. In the isthmus, the narrow segment

C. In the ampulla, the wider section of the tube

D. Within the intramural part, inside the uterus

Answer: (C)

Обяснение

Fertilization most commonly occurs in the ampulla of the fallopian tube, which is the widest and most suitable location for sperm and ovum to meet.

5. Where does fertilization most commonly occur within the female reproductive tract?

A. Ovary

B. Cervical canal

C. Ampulla of the fallopian tube

D. Fundus of the uterus

Answer: (C)

Обяснение

Fertilization most commonly occurs in the ampulla of the fallopian tube, which is the widest part of the tube and provides an optimal environment for sperm and ova to meet.

6. Which ligament is responsible for anterior support of the uterus, and what is its significance?

A. Uterosacral ligament, it supports the posterior aspect

B. Round ligament, it helps maintain the anteverted position

C. Cardinal ligament, it supports the lateral sides

D. Broad ligament, it encloses the reproductive organs

Answer: (B)

Обяснение

The round ligament provides anterior support and helps maintain the uterus in an anteverted position, important in pregnancy and pelvic anatomy.

7. What layers constitute the uterine wall, and which layer is responsible for contractions during labor?

A. Endometrium, myometrium, perimetrium; myometrium causes contractions

B. Myometrium, endometrium, serosa; serosa causes contractions

C. Perimetrium, endometrium, muscular layer; endometrium causes contractions

D. Serosa, mucosa, muscularis; muscularis causes contractions

Answer: (A)

Обяснение

The uterine wall has three layers: endometrium, myometrium, and perimetrium; the myometrium is the muscular layer responsible for contractions during labor.

8. Which nerve fibers innervate the uterus, and what functions do they serve?

A. Only sympathetic fibers, to induce relaxation

B. Parasympathetic fibers from pelvic splanchnic nerves, for vasodilation and pain sensation

C. Only parasympathetic fibers, for contractions

D. Somatic nerves, to control voluntary contractions

Answer: (B)

Обяснение

The uterus receives both sympathetic and parasympathetic innervation; parasympathetic fibers from pelvic splanchnic nerves mediate vasodilation and transmit pain signals.

9. During which phase of the menstrual cycle do ovaries typically release ova, and what is this process called?

A. During the luteal phase, called ovulation

B. During the follicular phase, called ovulation

C. During menstruation, called ovulation

D. During the secretory phase, called ovulation

Answer: (B)

Обяснение

Ova are usually released during the follicular phase of the menstrual cycle through a process called ovulation.

10. What is the significance of the broad ligament in the female reproductive system?

A. It encloses and supports the uterus, fallopian tubes, and ovaries

B. It serves as the main blood supply to the ovaries

C. It is a muscular layer of the uterus involved in contractions

D. It contains the nerve supply to the uterus and ovaries

Answer: (A)

Обяснение

The broad ligament is a peritoneal fold that encloses and helps support the uterus, fallopian tubes, and ovaries, maintaining their position within the pelvis.
