Question 1

Which structure in the female reproductive system is the common site of fertilization, and what specialized cells help move the oocyte through this structure?

Accepted Answer

Uterine tube (fallopian tube); ciliated epithelial cells

Question 2

During the ovarian cycle, which hormone surge triggers ovulation, and on approximately which day does this occur?

Accepted Answer

Luteinizing hormone (LH); day 14

Question 3

A patient presents with a lack of menstrual cycles due to failure of the endometrial functional layer to regenerate. Which phase of the uterine cycle is most likely disrupted?

Accepted Answer

Proliferative phase

Question 4

Which ligament anchors the ovary to the uterus, and which vessels travel through the suspensory ligament?

Accepted Answer

Ovarian ligament; ovarian arteries travel through the suspensory ligament

Question 5

Which layer of the uterine wall contracts during childbirth, and what type of muscle is it composed of?

Accepted Answer

Myometrium; smooth muscle

Question 6

A mutation prevents the formation of the zona pellucida during oogenesis. What is the most likely consequence for the oocyte?

Accepted Answer

Impaired sperm binding and fertilization

Question 7

Which structure in the male reproductive system is responsible for the wrinkling of the scrotal skin to reduce heat loss, and what type of muscle is it?

Accepted Answer

Dartos muscle; smooth muscle

Question 8

During spermatogenesis, which cells secrete androgen-binding protein to concentrate testosterone near developing sperm cells?

Accepted Answer

Sustentocytes (Sertoli cells)

Question 9

A patient has a blockage in the ductus deferens. Which process will be directly affected?

Accepted Answer

Transport of sperm from the epididymis to the urethra

Question 10

Which gland produces a mucus that neutralizes traces of acidic urine and lubricates the urethra prior to ejaculation?

Accepted Answer

Bulbo-urethral gland

Question 11

If the pampiniform plexus in the spermatic cord fails to function properly, what physiological consequence might occur?

Accepted Answer

Testicular temperature may rise, impairing spermatogenesis

Question 12

Which phase of the uterine cycle is characterized by the shedding of the functional layer of the endometrium, and what days does it typically occur?

Accepted Answer

Menstrual phase; days 1-5

Question 13

Which anatomical feature of the epididymis provides 'docking stations' for maturing sperm and is composed of immotile, long microvilli?

Accepted Answer

Stereocilia

Question 14

A patient with a mutation in the FSH receptor on granulosa cells would most likely have impaired conversion of androgens to estrogens. Which phase of the ovarian cycle would be most affected?

Accepted Answer

Follicular phase

Question 15

Which structure in the female external genitalia is homologous to the male scrotum?

Accepted Answer

Labia majora

Question 16

Which equation best represents the number of sperm produced per day if the average rate is 400 million sperm per day?

Accepted Answer

$$N_{sperm} = 4 	imes 10^8$

Question 17

Which layer of the ovary houses developing oocytes and follicles?

Accepted Answer

Ovarian cortex

Question 18

A patient with a congenital absence of the broad ligament would most likely experience which anatomical issue?

Accepted Answer

Uterus not anchored to lateral pelvic walls

Question 19

Which phase of the ovarian cycle involves the formation of the corpus luteum, and what hormone does it primarily secrete?

Accepted Answer

Luteal phase; progesterone

Question 20

If a patient has a mutation that prevents the degeneration of spiral arteries in the endometrium, what menstrual cycle phase would be most affected?

Accepted Answer

Menstrual phase
