male pelvic viscera Flashcards
what structures extends from the apex of the bladder
median umbilical ligament which is a remnant of the urachus
what structure is found on the bladder base
the trigone, between the ureteric orifices and the bladder neck
what are the relations of the bladder
ilium, sigmoid, rectovesical pouch, rectum, seminal vesicle
what is the venous drainage of the bladder
plexus on inferiolateral surface of the bladder, drains to internal iliac veins via vesicle veins
in the male also to the prostatic plexus that also drains to the internal iliac and internal vertebral venous plexus
what is the lymph drainage of the bladder
mainly to nodes on external iliac artery
what is the nerve supply of detrusor
p’symp derived from the pelvic splanchnic nerves
what is the nerve supply to the preprostatic sphincter
symp.
T12, L1, 2
what is the secretion of the prostate
slightly acidic seminal secretion, acid phosphatase, amylase, post spc antigen, fibrinolysin
how far above the pubic symphysis is the bladder when full
5-7 cm
what are the surfaces of the bladder
superior (posterior)
inferolateral x2
base(trigone)
what is the base of the bladder related to
prostate gland
sits on the pelvic floor
where is the bladder neck
3-4 cm behind the pubic symphysis
male has a preprostatic sphincter
what ligaments support the bladder
pubovesical in the female
puboprostatic in the male
what are fascial condensations
where fascia joins to form a supportive ligament
what is the blood supply of the bladder
internal iliac anterior trunk
superior vesical
inferior vesical/ vaginal
(obturator and inf gluteal)
what 3 plexuses are found in the bladder
mucosa
muscle
serosa
what is the lymph drainage of the bladder
external iliac artery mainly
what is the nerve supply of the bladder
anterior part of pelvic plexus that passes the rectum to reach the bladder creating a surgical risk
what is the nerve supply to detrusor
pelvic splanchnics S234 that reach detrusor via the pelvic plexus
what is the nerve supply to the internal sphincter
sympathetic
from T12, L1,2 via pelvic plexus
what fascia will trap urinary extravasation
scarpa’s and colles’
lower abdo, thighs, penis and scrotum
no further back than the perineal body
what urethra is found in the bulb of the penis
spongey
where does the preprostatic sphincter end
upper aspect of veru montanum
what are the relations of the prostate
denonvillier’s fascia and rectum
pubic symphysis and venous plexus
pelvic floor
what part of the prostate is fibromuscular
anterior
what prostate zone contains ejaculatory ducts
central
what zone is around the urethra and is the site of BPH
transition
what zone is around the transition zone is is most likely to get cancer
peripheral
what is the blood supply of the prostate and urethra
inferior vesicle
what is the blood supply of the female urethra
utero vaginal and internal pudendal
what are batson plexuses
valveless veins of the vertebral plexuses
what is the lymph drainage of the prostate and proximal urethra
internal iliac nodes
what is the nerve supply of the prostate
S2,3,4,
pudendal nerve and perineal branches
sympathetics from L1 and 2 via sup hypogastric plexus to pelvic plexus
p’symp to pelvic plexus
what does the M centre in the pons stimulate
preganglionic p’symp neurones - s2-4
where are the secondary neurones found
bladder wall ganglia
