|---|---|
 in spermatogenesis, the primary spermatocytes develop from the spermatogonia by process | of mitosis and differentiation |
| in penile erection, parasympathetic stimulation causes the constriction of ____ and the relaxation of ____ | arterio-venous shunt, helicine artery |
| in the testis, FSH causes the sertoli cells to secrete | androgen binding protein |
| give the two requirements for spermatogenesis | high local levels of testerone, intimate contact with sertoli cells |
| sperm are stored in and become functionally mature in the | epididymis |
| the primary spermatocyte develops from the ___ cell by the process of ____ | spermatogonia, mitosis and differentiation |
| in penile erection, the ___ artery relaxes in response to ___ stimulation | helicine, parasympathetic |
| name the location of the motile cilia | efferent duct |
| secretes a product high in prostaglandin and fructose | seminal vesicle |
| secretes a mucous like lubricant | bulbourethral gland |
| pseudostratified epithelium with sterocilia | epididymis |
| secretes a product high in acid phosphatase | prostate |
| absorbs most of the fluid secreted by seminiferous tubule | epididymis |
| the blood-testes barrier is formed by ____. what cells are not protected | sertoli cells with occluding junctions, spermatogonia |
| describe the function of the epidiymis | stores sperm, stimulates functional maturation |
| name the accessory glands of the male desribed: secretes a product high in fructose and prostaglandins | seminal vesicle |
| name the accessory glands of the male desribed: secretes acid phosphatase | prostate |
| what male reproductive organ has a duct that joins the ejculatory duct and it secretes a lubricating mucus | bulbourethral gland |
| what male reproductive organ secretes products which stimulate functional maturation of spermatozoa | epididymis |
| what male reproductive organ contains motile cilia | efferent duct |
| high local levels of testosterone are required for spermatogenesis. how is this accomplished | FSH causes sertoli cells to secrete androgen bindhing proteins which binds testosterone secreted by leydig cells to produce high levels in the seminiferous tubule |
| in spermatogenesis, cytokinesis is completed at the end of _____ | spermiogenesis |
| which male accessory gland secretes acid phosphatase and fibrinolysin | prostate |
| spermatozoa reach functional maturity in the the | epididymis |
| in penile erection, bloof flows from the ____ artery into the ____ | helicine artery, cavernous space |
| what cells comprise the lining of the prepubescent testis? | sertoli cells, germ cells |
| give two major requirements for spermatogenesis | intimate contact with sertoli cells, high local levels of testosterone |
| what is the most common disorder of the prostate gland | benign prostatic hyperplasia |
| in penile erection, _____ control causes the ____ arteries to contract. ____ stimulation causes the artery to dialate | sympathetic, helicine, parasympathetic |
| what cells are in the adluminal compartment fo the blood testis barrier | spermatogonia |
| the ___ cells secrete testosterone in response to ____ this is sequestered in the seminiferous tubule by ____. a molecule secreted by the sertoli cell in response to _____ | leydig cells, LH, androgen binding protein, FSH |
| in spermatogenesis, the primary spermatocytes develop from the spermatogonia by process of | mitosis and differentiation |
| what male reporductive organ may form condensations? | prostate |
| in addition to inhibition, the sertoli cell secretes ____ in response to ____. why is this vital | ABP, FSH, the ABP binds to the testosterone secreted by the leydig cells and this increases local levels of testosterone to facilitate spermatogenesis |
| what accessory reproductive gland in the male secretes prostaglandins | seminal vesicle |
| in which portoin of the male reproductive system do sperm reach functional maturity | epididymis |
| what is the first cell to become protected by the blood-testis barrier? why is this important | primary spermatocyte, if this cell was not protected the immune system would destroy it and thus spermatogenesis could not proceed |
| in penile erection, ____ stimulation causes both the relaxation of helicine artery smooth muscle and ____ allowing blood to enter the cavernous spaces | parasympathetic, constriction of the AV shunts |
| smooth muscle of the accessory glands and excretory ducts of the male repro system are innervated by | parasympathetics |
| name the male accessory gland which produces fructose, prostaglandins and flourescent flavins | seminal vesicle |
| name the male accessory gland which produces acid phosphatase | prostate |
| which cells are protected by the blood-testis barrier | 1st: primary spermatocyte, secondary spermatocyte, spermatid, spermatozoa |
| name the accessory male reproductive gland that may contain condensations of secretory material called corpora amylacea | prostate |
| name the accessory male reproductive gland that secretes prostaglandins and fructose | seminal vesicles |
| name the accessory male reproductive gland that produces a mucus like lubricant | bulbourethral gland |
| what possible functions are served by the blood testis barrier | protection of spermatids, 1 spermatocytes, 2 spermatocytes, spermatozoa, and maintenance of testosterone levels |
| the sertolie cell secretes two products in response to FSH, name them and give their functions | ABP--binds to testosterone to produce high local levels in seminiferous tubules, inhibin--provides negative feedback to turn off FSH |
| which ecretory ducts in the male repro system have motile cilia | efferent ducts |
| in order to achieve high local levels of testosterone, the sertoli cells secrete ____ in response to ____ | ABP, FSH |
| smooth muscle of the vas deferense is innervated by | parasympathetics |
| in spermatogenesis, the primary spermatocytes develop from spermatogonia by process of | mitosis and differentiation |
| where in the male repro tract would you find psuedostratified epi with stereocilia | epididymis |
| where is most of the fluid secreted by the seminiferous tubule absorbed | epididymis |
| what cells are not protected in the blood-testis barrier | spermatogonia |
