Questions and Answers
Which of the following accurately describes the relationship between the ovaries and the oviducts?
Which of the following accurately describes the relationship between the ovaries and the oviducts?
- The ovaries produce eggs which travel through the urethra to reach the oviducts.
- The ovaries are directly connected to the oviducts, allowing for seamless egg transfer.
- The ovaries are connected to the uterus, which then connects to the oviducts.
- The ovaries are not directly attached to the oviducts; the oviducts have funnel-shaped openings to receive eggs. (correct)
What is the primary function of the myometrium during pregnancy?
What is the primary function of the myometrium during pregnancy?
- To secrete hormones necessary for fetal development.
- To enable the uterus to expand and contract during pregnancy and childbirth. (correct)
- To facilitate nutrient exchange between mother and fetus.
- To provide a protective barrier against infection.
How does the structure of the cervix contribute to its function during childbirth?
How does the structure of the cervix contribute to its function during childbirth?
- It connects only to the urethra allowing for efficient waste removal during pregnancy.
- It secretes hormones that initiate labor.
- It is a rigid structure that protects the uterus from external trauma.
- It dilates significantly, connecting the uterine cavity and the vaginal cavity to allow the fetus to pass through. (correct)

Study Notes
- Semen comprises sperm and fluids from glands like the seminal vesicles and prostate gland.
- Semen contains fructose for sperm nourishment and has a pH that helps neutralize female reproductive tract acidity.
- The male genital organ, the penis, facilitates the exit of both urine and semen through the urethra.
Female Reproductive System
- It includes two ovaries, two oviducts (fallopian tubes), a uterus, and a vagina.
- Ovaries produce female gametes (eggs/ova) and sex hormones (estrogen/progesterone).
- Oviducts (fallopian tubes) receive eggs from the ovaries and conduct them to the uterus.
- The uterus is where the embryo develops, is normally the size of a clenched fist, and expands during pregnancy.
- The myometrium is the thick, smooth muscle layer of the uterus, and the endometrium is the inner mucous lining.
- The cervix is the neck-like structure at the base of the uterus, connecting the uterine and vaginal cavities.
- The vagina extends from the cervix to the body's exterior, receiving semen and serving as the birth canal.
- In females, the urethra is separate from the reproductive system.
Puberty
- Puberty is the period when humans become sexually mature.
- In males, sperm production begins during puberty and declines with age.
- In females, puberty marks the beginning of the menstrual cycle with the first ovulation.
- Male secondary sexual characteristics include pubic/facial hair, voice deepening, and muscle development.
- Female secondary sexual characteristics include breast development, pubic hair, and pelvis size increase.
- Females typically reach puberty earlier than males.
- Adolescence is the period between childhood and adulthood.
- Sex hormones drive the changes during puberty in both males and females.
- Testosterone increase in males is essential for sperm production and male secondary sexual characteristics.
- Estrogen increase in females triggers the first ovulation and female secondary sexual characteristics.
Male versus Female Gametes
- Sperm production starts at puberty in males, while egg formation in females begins before birth.
- At birth, females have 1-2 million immature eggs; about 400,000 remain by puberty.
- Typically, one ovary releases one mature egg each month via ovulation.
- Millions of sperm cells are in each semen release.
- Sperm and eggs are adapted for their functions and differ structurally.
- An egg cell is large, immotile, possesses a haploid nucleus, and is nutrient-rich.
- A surrounding jelly layer on an egg is important for fertilization.
- After sperm entry, this jelly layer hardens to prevent other sperm from entering.
