Question 2

Which portion of the uterus is shed during menstruation?

Accepted Answer

The stratum functionalis of the endometrium is shed during menstruation.

Question 3

Which follicle contains a secondary oocyte arrested in metaphase II?

Accepted Answer

The vesicular (tertiary) follicle contains a secondary oocyte that is arrested in metaphase II until fertilization occurs.

Question 4

During which phase of the uterine (menstrual) cycle will stratum functionalis develop with endometrial glands and spiral arteries and veins?

Accepted Answer

During the proliferative (preovulatory) phase, the stratum functionalis of the endometrium regenerates and thickens, developing endometrial glands and spiral arteries and veins in preparation for potential implantation.

Menopause is defined as the time when menstruation has ceased for at least one year, marking the end of a woman's reproductive years.

Question 6

Question 7

Estrogens are critical for:

Accepted Answer

Estrogens play a key role in the development of secondary sexual characteristics in females, including the distribution of adipose tissue in the breasts, hips, and thighs.

Question 8

Which of the following is NOT part of the female's external genitalia?

Question 10

Which of the following is regulated by a positive feedback mechanism in females?

Accepted Answer

Ovulation is regulated by a positive feedback mechanism in females. The rising levels of estrogen during the follicular phase trigger a surge in luteinizing hormone (LH) from the pituitary gland, which causes ovulation.

Question 11

Blockage to the mammary ducts of the mammary gland prevents the passage of:

Accepted Answer

The mammary ducts are responsible for transporting milk from the mammary glands to the nipple, so a blockage would prevent the passage of milk.

Accepted Answer

Ovulation is triggered by a surge in luteinizing hormone (LH), which is released by the pituitary gland.

Question 15

What effect do you think douching, or washing, has on the vagina?

Accepted Answer

Douching can disrupt the natural balance of bacteria and pH in the vagina, which can lead to infections and other issues.

Question 16

In a female, follicle ^-stimulating hormone (FSH) and luteinizing hormone (LH) target the:

Accepted Answer

FSH and LH are hormones that target the ovaries to regulate the menstrual cycle and stimulate the production of eggs.

Question 17

Which of the following can be fertilized?

Accepted Answer

The secondary oocyte is the cell that can be fertilized by a sperm cell during reproduction.

Question 18

Place these stages of the ovarian cycle in the correct order. 1) Corpus albicans
2) Vesicular (tertiary) follicle
3) Primary follicle
4) Ruptured follicle
5) Primordial follicle
6) Secondary follicle
7) Corpus luteum

Accepted Answer

The correct order of the ovarian cycle stages is: Primordial follicle (5), Primary follicle (3), Secondary follicle (6), Vesicular (tertiary) follicle (2), Ruptured follicle (4), Corpus luteum (7), Corpus albicans (1).

Question 19

Assuming a 28 ^-day ovarian cycle, on what day should ovulation occur?

Accepted Answer

In a typical 28-day ovarian cycle, ovulation usually occurs around day 14, which is approximately halfway through the cycle.
