31
in spermatogenesis, (spermatogonia/spermatocytes) divide in second meitoic division
spermatocytes
32
release of spermatozoa from Sertoli cells is called
spermiation
33
where are mitochondria concentrated on the spermatozoa
proximal tail
34
(Sertoli cells/epididymus): support germ cells, phagocytosis, secretion, blood-testis barrier
Sertoli
35
(Sertoli cells/epididymus): maturation of sperm, reabsorption of testicular fluid, phagocytosis, contraction to expel sperm during ejaculation
epididymus
36
(Sertoli/Leydig) cells: produce testosterone
Leydig
37
(Leydig/Sertoli) cells: secrete androgen binding protein to concentrate testosterone in seminiferous tubules
Sertoli
38
what is cryptochridism
failure of testes to drop--bad because they get too hot
39
most of the testicular fluid is produced by (Sertoli/ductus epididymus)
Sertoli
40
most of the testicular fluid is absorbed by (Sertoli/ductus epididymus)
ductus epididymus
41
(epididymus/vas deferens): stereocilia
vas deferens
42
passive sperm transport (seminiferous tubules to ductuli efferentes/ductuli efferentes to urethra)
seminiferous tubules to ductuli efferentes
43
active sperm transport (seminiferous tubules to ductuli efferentes/ductuli efferentes to urethra)
ductuli efferentes to urethra
44
secretions from (prostate/seminal vesicles/Littre) liquefy the semen
prostate
45
secretions from (prostate/seminal vesicles/Littre) have fructose
seminal vesicles
46
secretions from (prostate/seminal vesicles/Littre) lubricate the penile urethra
Littre
47
order that secretions from accessory glands are released during ejaculation
Bulburethral + Littre then prostate and spermatozoa then seminal vesicle fluid
48
secretions from (prostate/seminal vesicles/Littre) add the greatest volume to semen
seminal vesicles
49
(transition/central/peripheral) zone of the prostate: surrounds urethra
transition
50
(transition/central/peripheral) zone of the prostate: surrounds ejaculatory ducts

transition
53
what are prostatic concretions
calcified prostatic secretion forming concentric condensations--observed in lumen of glands
54
are increased prostate specific antigen (PSA) levels diagnostic of prostate cancer?
no--they can occur with BPH and inflammation. Diagnosis requires needle biopsy
