Question 1

The layer of glycoproteins between the oocytes and granulosa cells is called the
A) Corona radiata
B) Cumulus oophorus
C) Macula pellucida
D) Theca folliculus
E) Zona pellucida

Accepted Answer

The zona pellucida is the glycoprotein layer surrounding the plasma membrane of mammalian oocytes, situated between the oocyte and the granulosa cells.

Question 2

Which of the following does not occur as a result of the luteinizing hormone surge?
A) Formation of the corpus luteum
B) Increased estrogen secretion
C) Ovulation
D) Secondary oocyte completes meiosis I
E) Secretion of proteolytic enzymes from the mature follicle

Accepted Answer

D

Question 3

Where is the bulbospongiosus muscle found?
A) In the cervix
B) In the ovary
C) In the oviduct
D) In the uterus
E) In the vagina

Accepted Answer

The bulbospongiosus muscle is found in the vagina. It is a muscle that surrounds the entrance of the vagina and plays a role in sexual function and urination.

Question 4

The inner layer of the uterus is called the
A) Cervix
B) Endometrium
C) Germinal epithelium
D) Mesovarium
E) Myometrium

Accepted Answer

The inner layer of the uterus, which is responsible for menstruation, implantation, and pregnancy, is called the endometrium.

Question 5

The thick fibromuscular layer of the uterus is the
A) Cervix
B) Cortex
C) Endometrium
D) Myometrium
E) Tunica albuginea

Accepted Answer

The thick fibromuscular layer of the uterus is called the myometrium. The cervix is the lower part of the uterus that connects to the vagina. The cortex and tunica albuginea are terms used in relation to the structure of the ovaries, not the uterus. The endometrium is the inner lining of the uterus.

Question 6

Developing follicles are found in the
A) Ovarian cortex
B) Ovarian medulla
C) Oviduct
D) Tunica albuginea
E) Uterus

Accepted Answer

Developing follicles are found in the ovarian cortex, which is the outer layer of the ovary. The ovarian medulla is the inner layer of the ovary and contains blood vessels and connective tissue. The oviduct (also known as the fallopian tube) is not where follicles develop but instead is where the fertilization of the egg by sperm takes place. The tunica albuginea is a fibrous membrane that surrounds the ovary, but it does not contain follicles. The uterus is where the fertilized egg implants and develops into a fetus, but it is not where follicles develop.

Question 7

Oocytes surrounded by granulosa cells are found in the
A) Corona radiata
B) Corpus luteum
C) Cumulus oophorus
D) Theca folliculus
E) Zona pellucida

Accepted Answer

Oocytes surrounded by granulosa cells are found in the cumulus oophorus. The corona radiata consists of layers of granulosa cells that surround the oocyte after it is released from the follicle. The corpus luteum is the remains of the follicle after ovulation and is composed of luteinized granulosa and theca cells. The theca folliculi is a layer of cells surrounding the follicle that secretes androgens. The zona pellucida is an extracellular glycoprotein matrix that surrounds the oocyte.

Question 8

Which of the following statements about the corpus luteum is incorrect?
A) It degenerates into the corpus albicans approximately 14 days following fertilization
B) It forms following ovulation
C) It has increased vascularization
D) Its folded structure is formed by the collapsing of the follicular wall
E) The theca interna and granulosa cells accumulate lutein

Accepted Answer

The corpus luteum does degenerate into the corpus albicans, but this typically occurs 14 days after ovulation, not fertilization. Following fertilization, the corpus luteum will continue to produce hormones to support the early stages of pregnancy.

Question 9

Which ovarian follicle has a simple cuboidal epithelium?
A) Mature follicle
B) Primary follicle
C) Primordial follicle
D) Secondary follicle
E) Both B and D have simple cuboidal epithelia

Accepted Answer

The primary follicle has a single layer of granulosa cells surrounding the oocyte, which form a simple cuboidal epithelium. The other stages of follicular development, including the secondary follicle and mature follicle, have stratified or pseudostratified epithelia. The primordial follicle has a squamous epithelium.

Question 10

During which stage of the endometrial cycle is mitotic activity most intense?
A) Early proliferative period
B) Ischemic period
C) Late proliferative period
D) Midproliferative period
E) Midsecretory period

Accepted Answer

The late proliferative period is when mitotic activity is most intense as the endometrium prepares for potential implantation by thickening and regenerating after menstruation.
