Which type of epithelium covers the surface of the ovary?

• Transitional epithelium

• Germinal epithelium

• Stratified squamous epithelium

• Pseudostratified columnar epithelium

If a histological section of the ovary shows a region with loose connective tissue and blood vessels, which region is it most likely to be?

• Germinal epithelium

• Cortex

• Medulla

• Ovarian follicle

Which of the following best describes ovarian follicles?

• Small, fluid-filled sacs in the ovaries that contain oocytes

• Large, solid masses in the uterus that contain sperm

• Small, fluid-filled sacs in the kidneys that filter blood

• Large, fluid-filled sacs in the liver that store bile

Growing follicles are further subcategorized as which of the following?

What hormone stimulates the growth of primary follicles at the beginning of each ovarian cycle?

• Luteinizing hormone (LH)

• Follicle-stimulating hormone (FSH)

• Estrogen

• Progesterone

What is the role of LH in progesterone production during the ovarian cycle?

• LH inhibits progesterone production

• LH stimulates progesterone production by cells in the ovary

• LH has no effect on progesterone

• LH stimulates oestrogen production only

• Increase in basal body temperature

• Decrease in blood pressure

• Increase in heart rate

What is the main function of the corpus luteum after ovulation?

• To secrete hormones necessary for the preparation of the uterine mucosa for embryo implantation

• To produce eggs for fertilization

• To initiate menstruation

• To dissolve the follicle cells
