#12
Which of the following glands produces a fluid that lubricates the urethra and neutralizes acidic urine residue in the urethra?
Cowper's glands (bulbourethral glands)
ExplanationCowper's glands produce a fluid that lubricates and neutralizes acidic urine residue in the urethra.
#13
What is the name of the structure that connects the testes to the rest of the reproductive system and contains blood vessels, nerves, and the vas deferens?
Spermatic cord
ExplanationThe spermatic cord connects the testes to the rest of the reproductive system and contains blood vessels, nerves, and the vas deferens.
#14
What is the function of the vas deferens?
Transportation of sperm from the testes to the urethra
ExplanationThe vas deferens transports sperm from the testes to the urethra for ejaculation.
#15
Which structure surrounds the testes and helps regulate their temperature?
Scrotum
ExplanationThe scrotum surrounds the testes and helps regulate their temperature by adjusting its position.
#16
Which of the following structures is responsible for producing the alkaline fluid that helps neutralize the acidic environment of the urethra?
Cowper's glands (bulbourethral glands)
ExplanationCowper's glands produce alkaline fluid to neutralize the acidic environment of the urethra.
#17
Which of the following structures is responsible for the propulsion of sperm during ejaculation?
Vas deferens
ExplanationThe vas deferens propels sperm during ejaculation.
#18
What is the function of the seminiferous tubules within the testes?
Production of sperm
ExplanationSeminiferous tubules in the testes produce sperm through spermatogenesis.
#19
What is the function of the seminal vesicles in male reproductive system?
Production of seminal fluid
ExplanationThe seminal vesicles produce seminal fluid, which nourishes and protects sperm.
#20
What is the purpose of the cremaster muscle?
To regulate temperature in the scrotum
ExplanationThe cremaster muscle helps regulate temperature by adjusting the position of the testes in the scrotum.
#21
What is the medical term for the surgical procedure of cutting and sealing the vas deferens to prevent sperm from being ejaculated?
Vasectomy
ExplanationA vasectomy involves cutting and sealing the vas deferens to prevent sperm from being ejaculated during ejaculation.
#22
What is the function of the bulbospongiosus muscle?
To aid in erection by compressing the dorsal vein of the penis
ExplanationThe bulbospongiosus muscle aids in erection by compressing the dorsal vein of the penis.
#23
Which of the following structures is responsible for transporting sperm from the testes to the urethra?
Vas deferens
ExplanationThe vas deferens transports sperm from the testes to the urethra.
#24
What is the purpose of the dartos muscle in the scrotum?
To regulate temperature by contracting or relaxing
ExplanationThe dartos muscle contracts or relaxes to adjust the temperature in the scrotum.
#25
Which of the following hormones is primarily responsible for regulating spermatogenesis in the testes?
Follicle-stimulating hormone (FSH)
ExplanationFollicle-stimulating hormone (FSH) primarily regulates spermatogenesis in the testes.
