Example Questions
Example Question #71 : Systems Physiology
Which male reproductive structure is responsible for the storage of sperm cells?
Seminiferous tubules
Prostate gland
Vas deferens
Epididymis
Epididymis
After developing in the seminiferous tubules, sperm cells are transferred to the epididymis in order to be stored prior to ejaculation. The sperm cells also mature further and develop the ability to swim in the epididymis.
The vas deferens is the duct connecting the epididymis to the ejaculatory ducts. The prostate gland, bulbourethral gland, and seminal vesicles produce alkaline and lubricating fluids for the composition of semen.
Example Question #72 : Systems Physiology
Which of the following glands does NOT contribute to seminal fluid?
The seminal vesicles
The bulbourethral glands
The testes
The prostate
The testes
Semen is composed of fluid from the three following glands: the seminal vesicles, the prostate, and the bulbourethral glands. These glands secrete alkaline fluids that help neutralize the acidity of the vagina, preventing degradation and damage of sperm.
The testes are the site of development for sperm cells, but they do not contribute to the fluidity of semen.
Example Question #73 : Systems Physiology
Which process describes the quick discharge of semen from the male human body?
Emission
Ejaculation
Spermatogenesis
Gestation
Oogenesis
Ejaculation
By definition, ejaculation is the process by which sperm is released. This process usually occurs during the orgasm stage of the sexual response cycle in males. Emission is the phase directly preceding ejaculation in which the sperm are prepared for release. Spermatogenesis is constantly occurring and occurs within the seminiferous tubules. Oogenesis and gestation are female-associated.
Example Question #74 : Systems Physiology
Which of the following allows for fluids such as urine and semen to leave the body?
Vas deferens
Seminiferous tubules
Urethra
Epididymis
Seminal vesicles
Urethra
In males, the urethra is the vessel that allows for the excretion/expulsion of semen and urine. The seminiferous tubules and epididymis are located in the testes, and are involved in spermatogenesis. The vas deferens is the vessel that carries sperm and semen from the testes to the urethra, picking up seminal fluids from the seminal vesicle and prostate gland.
Example Question #75 : Systems Physiology
Which of these structures functions in the maturation and storage of sperm?
Ejaculatory duct
Seminal vesicles
Testis
Epididymis
Epididymis
The epididymis is an anatomical structure in the male reproductive system. It functions in the maturation and storage of spermatozoa and in propulsion of the spermatozoa into the vas deferens. The ejaculatory duct is responsible for propelling spermatozoa with seminal fluid into the urethra. The testis is responsible for producing spermatozoa and secreting the sex hormones. Lastly, the seminal vesicles are responsible for producing the alkaline component of seminal fluid.
