Question 1

The ________ produces estrogen and progesterone,which facilitate maintenance of the uterine wall in the early stages of pregnancy.&#10;A) corpus albicans&#10;B) oocyte&#10;C) corona radiata&#10;D) corpus luteum

Accepted Answer

The corpus luteum is a temporary endocrine gland that forms from the ruptured follicle after ovulation. It produces estrogen and progesterone that facilitate maintenance of the uterine wall in the early stages of pregnancy, preparing it for implantation of a fertilized egg. The other options, corpus albicans, oocyte, and corona radiata, do not have this function.

Question 2

________ produce breast milk.&#10;A) Uterine glands&#10;B) Sweat glands&#10;C) Mammary glands&#10;D) Greater vestibular glands

Accepted Answer

Mammary glands exclusively produce breast milk. Uterine glands produce uterine secretions, sweat glands produce sweat, and greater vestibular glands produce vaginal lubrication.

Question 3

Breast milk is stored in the ________ prior to breastfeeding.&#10;A) lactiferous sinus&#10;B) lobules&#10;C) nipple&#10;D) lactiferous duct

Accepted Answer

Milk is produced in the lobules of the breast, which are connected to the nipple by a network of ducts. The lactiferous ducts widen at the base of the nipple to form the lactiferous sinuses, which act as storage reservoirs for breast milk before it is released during breastfeeding. Therefore, the correct answer is A) lactiferous sinus.

Question 4

Which of the following structures serves as the site of fetal development?&#10;A) uterine (fallopian) tubes&#10;B) vagina&#10;C) ovaries&#10;D) uterus

Accepted Answer

The uterus serves as the site of fetal development during pregnancy.

Question 5

Which of the following structures plays a critical role in maintaining the early pregnancy?&#10;A) corpus albicans&#10;B) primordial follicle&#10;C) corpus luteum&#10;D) corona radiata

Accepted Answer

The corpus luteum is formed from the ruptured follicle after ovulation and plays a critical role in maintaining the early pregnancy by secreting progesterone. Progesterone is necessary to maintain the uterine lining and prevent menstruation, allowing the developing embryo to implant and continue to grow. The other structures listed (corpus albicans, primordial follicle, and corona radiata) do not have a significant role in maintaining early pregnancy.

Question 6

Which phase of the menstrual cycle is characterized by the formation of new glands,thickening of the endometrium,and infiltration of blood vessels?&#10;A) secretory&#10;B) menstrual&#10;C) luteal&#10;D) proliferative

Accepted Answer

The proliferative phase is characterized by the formation of new glands, thickening of the endometrium, and infiltration of blood vessels. This phase occurs after menstruation and is driven by rising levels of estrogen.

Question 7

Which reproductive accessory organ serves as the birth canal and receives semen during intercourse?&#10;A) uterine (fallopian) tubes&#10;B) ovary&#10;C) vagina&#10;D) uterus

Accepted Answer

The vagina is a reproductive accessory organ that functions as the birth canal and receives semen during intercourse. The uterus is where the fertilized egg implants and grows during pregnancy, the uterine (fallopian) tubes transport the egg from the ovary to the uterus, and the ovary produces and releases eggs.

Question 8

Ovulation is stimulated by ________,which is released from the anterior pituitary gland.&#10;A) progesterone&#10;B) estrogen&#10;C) testosterone&#10;D) luteinizing hormone

Accepted Answer

Ovulation is stimulated by luteinizing hormone, which is released from the anterior pituitary gland. Luteinizing hormone causes the mature follicle to rupture and release the egg into the fallopian tube.

Question 9

Which of the following pairings represents homologous structures?&#10;A) labia majora : labia minora&#10;B) ovary : testis&#10;C) clitoris : testis&#10;D) ovary : scrotum

Accepted Answer

Homologous structures are structures that are similar in different organisms because they share a common ancestry. The ovary and testis are homologous structures because they both develop from the same embryonic tissue (gonadal tissue) and serve the same function in producing gametes (eggs or sperm). The labia majora and labia minora are also similar in function and location, but they are not considered homologous because they develop from different embryonic tissues. The clitoris and testis are not homologous structures because they have different functions and develop from different tissues. The ovary and scrotum are also not homologous structures because they have different functions and develop from different tissues.

Question 10

The ovarian ________ contains developing egg cells,while the ________ contains the blood vessels,nerves,and lymphatic vessels that supply the ovary.&#10;A) medulla; cortex&#10;B) cortex; medulla&#10;C) cortex; follicle&#10;D) medulla; follicle

Accepted Answer

The ovarian cortex contains developing egg cells (follicles), while the medulla contains the blood vessels, nerves, and lymphatic vessels that supply the ovary.
