- Why is the term urogenital system more applicable to males than to females?arrow_forwardTRUE OR FALSE Sympathetic stimulation of the arteries within the penis causes engorgement of the erectile tissue as arterial flow increases and venous drainage decreases. Mammary glands are modified sudoriferous glands. Prolactin causes the breasts to enlarge and the mammary glands to mature during puberty. Secretions from the vestibular glands moisten and lubricate the vaginal orifice during sexual arousal. 20. The secretory phase of menstruation is from the time of ovulation until the start of the menstrual phase.arrow_forwardSildenafil citrate (marketed under the name ‘Viagra’) causes increased blood flow into the penis, thus allowing for erection to occur. Explain the mechanism by which this drug accomplishes this? What hormone is primarily responsible for the Graafian follicle rupturing to release the oocyte at ovulation?arrow_forward
- Hypospadias is a birth defect in which the external urethral office does not appear at the tip of the penis, but somewhere on the underside of the penis. Discuss one urinary complication of having this defect and one reproductive complication of having this defect.arrow_forwardParasympathetic neurons in the male reproductive system secrete the following substance: nitric olde testosterone adenosine aldosteronearrow_forwardA normal discharge from the glans penis is called penorrhea. True False.arrow_forward
- Sexual arousal results in a generally positive sympathetic response, e.g. increased heart rate, increased breathing rate and depth, etc. How is it, then, that erection can occur if sympathetic activity causes vasoconstriction and prevents blood flow into the vascular spaces of the penis?arrow_forwardIdentify the vessel located between the renal pyramids A) peritubular capillary B) interlobar artery D) segmental artery E) cortical radiate artery F) renal arteryarrow_forwardGross Anatomy of the Human Male and Female Reproductive System a) What structures compose the spermatic cord and Where is it located? b) Using the following terms, trace the pathway of sperm from the testes to the urethra: rete testis, epididymis, seminiferous tubule, ductus deferens. c) Name the structures composing the external genitalia, or vulva, of the female.arrow_forward
- What is the female homologue of the bulbo-urethral glands of males?arrow_forwardThe order of ducts in the male genital system: Select one: O a. Tubuli recti- Rete testis- Vasa efferentia- Ejacutatory duct b. Tubuli recti- Rete testis- Vasa efferentia- epididymis c. Rete testis- Tubuli recti- Vasa efferentia- epididymis d. Vasa efferentia- Ejacutatory duct- Epididymis O The connective tissue layer of a mucous membrane is named:arrow_forwardList the common infertility problems in women. Which is the most (or one of the most) common? Describe this condition. List the most common infertility problems in men. Which is the most (or one of the most) common?
