Bladder, Pelvic Vessels, Nerves & Lymphatics Flashcards
Ureter (retroperitoneal)
25-30 cm muscular tubes
Carry urine
Junction w/ bladder - ureterovesical junction
Runs posterolateral to ductus deferens (Males)
Bladder (retroperitoneal)
Lies deep to peritoneal membrane
Bladder Borders
Anterior - pubic symphysis
Posterior - rectum in males, uterus & vagine in females
Inferior - prostate in males, pelvic diaphragm in females
Bladder Musculature
Detrusor muscles
Contraction increases internal pressure lead to micturition when urethral sphincter is open
Sphincter closed if bladder has less than 250 ml of urine
Bladder Innervation
Parasympathetic - S2-4
Sympathetic - T11, L1-2
Sciatic Nerve Origin
L4-S3
Sciatic Nerve Distribution
Flexors of knee
All muscles of leg & foot
Superior Gluteal Origin
L4-S1
Superior Gluteal Distribution
Glute med/min
Inferior Gluteal Origin
L5-S2
Inferior Gluteal Distribution
Glute max
Pudendal Origin
S2-4
Pudendal Distribution
External urethra
Anal sphincters
Motor/sensory to external genitalia
