Male Reproductive Flashcards
function of pelvic girdle
facilitate transfer of weight from upper body and trunk to lower extremities
function of pelvic diaphragm
thin muscular sling that fors the pelvic floor and supports the pelvis and some of the abdominal viscera
pelvic inlet
line from pubic symphysis to sacral promontory
pelvic outlet
line from inferior aspect of the pubic symphysis anteriorly to the tip of coccyx posteriorly
3 bones that make up pelvic girdle
paired hip bones and sacrum
what fuses to form the hip bones
pubis
ilium
ischium
where do the hip bones articulate with the sacrum
sacroiliac joints
characteristics of ilium
ala
iliac fossa surrounded by iliac crest
anterior superior and anterior inferioir iliac spines
which muscles make up the pelvic diaphragm
levator ani and coccygeus muscle
what is the name of the opening between the left and right sides of the pelvic diaphragm
urogenital hiatus
what is the scrotum made of
skin
dartos muscle
3 layers of spermatic fascia
each testicle is enclosed by a thick covering of connective tissue called
tunica albuginea
the tunica albuginea specialized to form what
mediastinum testis
what is the significance of the mediastinum testis
divide the testicles into lobules
what is contained within the lobules of the tesicles and what is the fucntion
seminiferous tubules
produce spermatozoa
what surrounds the seminiferous tubules and what do the cells within produce
connective tissue
interstitial cells of lyedig produce testosterone
what duct is formed by the intersection of the vas deferens and the seminal vesicle
ejactulatory duct
what temperature is best for sperm
below 37 degrees
contents of the spermatic cord
pampiniform plexus vas deferens cremasteric artery testicular artery genital branch of genitofemoral nerve sympathetics lymphatics
coverings of the spermatic cord
external spermatic fascia
creamaster muscle and fascia
internal spermatic fascia
what covers the crura
isciocavernous muscles
what is formed when the crura fuse
corpora cavernosa on the shaft of the penis
what is enclosed within the bulbospongiosus muscle
urethra
what are the components of the shaft of the penis
paired corpora cavernosa
corpus spongiosum
what are the components of the shaft enclosed within
deep (bucks) fascia
what does bucks fascia enclose besides the cylinders of the shaft
deep dorsal vein
deep dorsal nerves
what exits at the glans of the penis
external urethral meatus orifice
where do the testicular arteries originate from
abdominal aorta (L2)
where do the testicular veins originate
pampiniform venous plexus
where does the left testicular vein drain
left renal vein
where does the rught testicular vein drain
inferior vena cave
where do the lymph vessels of the testes terminate
para-aortic or lumbar lymph nodes (L1-L2)
what is the internal pudental artery a branch of
internal iliac artery
how many terminal branches does the internal pudental artery send to the penis? what are they
paired deep dorsal arteries
paired deep central arteries
where does the deep dorsal vein drain
prostatic and vesicle venous plexi–> internal iliac veins
vas deferns
conduit between epididymis and ejaculatory duct
what does the vas deferns enlarge to form
ampulla of vas deferens
where does the ejeculatory duct pass through and open into
passes through prostate
opens into prostatic urethra
what gives sperm energy in the seminal vesicles
fructose
function of the prostate
produces fluids that promote sperm motility and fertilization
BPH
hyperplasia of the prostate; enlarged middle lobe of the bland pushes onthe bladder and makes it hard to pee
TURP
what surface of the prostate can be palpated
posterior via rectum
what does the membranous urethra connect
prostatic with the spongy urethra
what is the spongy urethra adjacent to
bulbourethral (cowpers) glands
function of bulbourethral glands
produce mucous-like secretion during sexual arousal
