Pelvic Nerves And Vessels Flashcards
Sacral plexus
Superior gluteal- L4,5,S1
Inferior gluteal- L5,S1,2
Sciatic- L4,5,S1,2,3
Pudendal- S2,3,4
Where does it go, Sciatic nerve?
Posterior compartment of thigh and branches supply all muscle of leg and foot
Sciatic nerve branches
Tibial nerve- calf and foot
Common fibular nerve- anterior leg
Gluteal nerves, supply?
Superior- gluteus medius and minimums
Inferior- gluteus maximums
Nerve to obturator internus root?
L5-S1
Nerve to Piriformis root
S1-2
Levator ani innervation
S4 pudendal
Coccygeus innervation
S4,5
What does pudendal nerve innervate?
Levator ani External anal External urethral sphincters Bulbospongiosus Ischiocavernosus
Male- penis nerves
Dorsal nerve of penis from pudendal nerve
Cavernous nerve form prostatic nerve plexus
Bulbospongiosus and ischocavernosus nerve
Perineal branch from pudendal nerve
Scrotum innervation
Anterior scrotal from ilioinguinal and genitofermoral
Posterior scrotal from perineal branch of pudendal
Female innervation
Anterior perineum- anterior labial form ilioinguinal and genitofemoral
Posterior perineum- perineal branch form pudendal, posterior cutaneous of thigh
Labia- posterior labial from pudendal
Orifice of vagina- deep branch form pudendal
Clitoris- macula branch from pudendal
Bulb of vesicle- cavernous nerve from utero-vaginal plexus and clitoris
Vessels form abdominal aorta
L4 aorta divides- 2 common iliac arteries
Common iliac divide into internal and external iliac
Pelvis supplied by internal iliac
Internal iliac divides into anterior and posterior
Anterior divison of internal iliac
Umbillical- supeiror vesicle Obturator Inferior vesicle/ uterine Middle rectal Inferior gluteal Internal pudendal
