Example Questions
Example Question #1 : Reproductive System
Which part of the male reproductive system is responsible for sperm storage and maturation?
Testes
Vas deferens
Seminal vesicles
Epididymis
Epididymis
Sperm cells are stored and mature in the epididymis until they are transported to the urethra through the vas deferens. The testes are the site of sperm production, while the seminal vesicles produce fluids that are later incorporated into semen.
Example Question #223 : Systems Physiology
Which of the following glands contribute to the production of semen?
Bulbourethral glands
Prostate gland
All of the other choices are correct
Seminal vesicles
All of the other choices are correct
The seminal vesicles secrete seminal fluid to promote and nourish sperm as they are released. The bulbourethral glands secrete a component of seminal fluid, while the prostate gland secretes alkaline fluid.
Example Question #1 : Reproductive System
Which of the following is responsible for the production of germ cells?
Fallopian tubes
Ovaries
Endometrium
Uterus
Ovaries
"Germ cells" is simply another term for gametes, and thus refers to either sperm or ovum.
Ovum are produced in the ovaries. After production, the fallopian tubes propel ovum to the uterus using the movement of cilia. The endometrium is the lining of the uterus, and allows for implantation of a fertilized ovum.
Example Question #4 : Reproductive System
Where does fertilization typically take place in the female?
Uterus
Ovary
Fallopian tubes
Cervix
Fallopian tubes
In the majority of cases, fertilization occurs in the fallopian tubes of the female. The egg is released from the ovary and travels into the fallopian tube during ovulation. Sperm travel to the fallopian tube to fertilize the egg, creating a zygote. The zygote begins to divide, forming a blastocyst before it reaches the uterus where it becomes embedded in the endometrium via the process of implantation. Certain pregnancy complications can arise if the blastocyst implants while still in the fallopian tube, resulting in ectopic pregnancy.
Example Question #5 : Understanding Internal Anatomy
What is the site of sperm maturation and storage in males?
Epididymis
Prostate
Seminiferous tubules
Vas deferens
Epididymis
Sperm is created in the seminiferous tubules of the testes. It is then transported to the epididymis, where it will mature and be stored prior to ejaculation.
Example Question #5 : Reproductive System
The epididymis, vas deferens, and urethra are a series of ducts found in which body system?
Lymphatic
Integumentary
Endocrine
Digestive
Male reproductive
Male reproductive
The male reproductive system consists of a series of ducts, which includes the epididymis, vas deferens, and urethra. The epididymis is a coiled tube attached to the testis, which receives sperm from the seminiferous tubules. The vas deferens connects the epididymis with the urethra, which in turn conducts sperm to the tip of the penis.
Example Question #6 : Reproductive System
What term refers to the finger-like folds that line the fallopian tubes?
Flagella
Microtubules
Endoderm
Fimbriae
Villi
Fimbriae
In female mammals, the fimbriae are finger-like projections that sweep the ovulated egg from the ovary into the oviduct.
Villi are found in the digestive tract and work to increase surface area for more efficient absorption of nutrients. Flagella are threadlike structures that provide motility for sperm. Microtubules are composed of the protein tubulin, and are used in the construction of cilia and flagella. The endoderm is the innermost embryonic tissue layer, which develops to form the lining of the respiratory and digestive tracts.
Example Question #1 : Reproductive System
Men and women are composed of the same cells, though distributed differently. Based on their cell composition, the _____ in boys is akin to the clitoris in girls.
urethra
testicles
perineum
shaft
glans
glans
The glans is the correct answer here. It is composes of the same types of cells as the clitoris.
