ch 27 Flashcards
4 major parts of male reproductive system
gonads
ducts
glands
external genitalia
for males the gonads are
testes
reproductive tract for men contain
epydidimis
vas deferens
male reproductive glands
seminial gland
prostate
testes located in the
scrotum
scrotum sac anterior to
perineum
dartos muscle wrinkles
scrotum
two muscles for scrotum
dartos muscle
cremaster muscle
cremaster muscle pulls
testes to the body
testes begin development in the
periotneal cavity
7th month of gestation
testis push through the floor to make the inguinal
inguinal hernia is when
small intestine passes into the inguinal canals
if testes do not descend
cryptorchidism
spermatic cord passes through
inguinal canal
spermatic cord parts
pampiniform plexus
testiculary artery
pampiniform plexus helps
cool down blood
vas deferens goes from
epidymis to urethra
interstitial endocrine leydig cells produce
androgens aka testostorone
nurse sertoli cells functions
secrete hormones, support sperm development/maturation and maintain blood testis barrier
spermatogeneis produces
4 haploid cells called spermatids
spermatids undergo spermiogenesis to produce
matuere sperm
tail of sperm called
flagellum
head of sperm is called
acrosome
sperm development takes
7 weeks
epidiymis is lined with
pseudostratified ciliated columnar epithelium
ductus vas deferns lined with
pseudostratified ciliated columnar epithelium
ductus vas deferens begins at
tail of epididymis
ductus vas deferens ascends through the
inguinal canal to ureter
ampulla is where you see
vas deferens join with seminal gland to make ejaculatory duct
urethra carries
sperm to urethral meatus
prostate secretes
milkly slightly acidic fluid with antibiotic compound
30% of semen volume is in
prostate
seminal glands compose
60% of semen volume
seminal glands produce
alkaline
fructuose
cowpers glands produce
alkaline mucus
cowpers function
lubricate glans penis and neutralize trqaces of urine in urethra
5% of semen volume
cowpers glands
semen per ejaculate
2-5 ml
penis three parts
root
body
glans penis
glans penis covered by
prepuce aka foreksin
erection reflex controled by
parasympathetic ns
emission/ejactualtion are stimulated by
sympathetic NS
what surrounds spongy urethra
corpus spongiosum
