male reproductive Flashcards
primary gonads in male
testes
accessory sex organs in male
ducts, tubules leading to the penis. A group of male accessory glands and the penis
supports and protects the testes and is located at the base of the penis
scrotum
why is one testis usually lower than the other
allows them to avoid collusions when they are compressed towards the midline
ideal temperature for sperm production in the scrotum
94 degrees F
divides scrotum into left and right halves
fibrous septum
seam that extends from the anus to the scrotum and up the bottom side of the penis
raphe
smooth muscle that wrinkles the scrotum
dartos
skeletal muscle that raises and lowers the testes
cremaster
what will pull the testes closer to warm core of the body when it is cold
contraction of the dartos and cremaster
tunica vaginalis
surrounds testis
has parietal and visceral layers
where is sperm produced
in the seminiferous tubules
these assist with sperm development, provide a protective environment and create a barrier between sperm cells and the circulatory system
sustentacular cells
produce testosterone
interstitial cells
these cause males to develop male characteristics at puberty
androgens (most common is testosterone)
where do the teses get blood from
testicular arteries
where does the right testicular vein drain into
inferior vena cava
where does the left testicular vein drain into
left renal vein
inflammation of one or both testes
orchitis
structures within the spermatic cord
ductus deferens (vas deferens)
pampiniform plexus
testicular artery
testicular nerve
how long does it take for sperm to develop
2 weeks
path of sperm
- seminiferous tubules
- rete tesis
- efferent ductules
- epididymis
- ductus deferens
- ampula
- ejaculatory duct
- prostatic urethra
- spongy urethra
long flattened organ attached to the posterior of the testis
epididymis
where is sperm stored until they are fully mature and capable of being motile
epididymis
