Lecture 23 + Lecture 24 Flashcards
Boundaries of the adbominalpelvic cavity?
upper = thoraco-abdominal diaphragm
lower = pelvic diaphragm
pelvic inlet
parietal peritoneum
What are the vertebral levels of the IVC, esophagus, and aorta
IVC = T8
esophagus = T10
aorta = T12
Innervation and blood supply of the diaphragm?
Phrenic nerves C3,C4,C5
superior and inferior phrenic arteries
muscleophrenic artery
pericardiophrenic artery
Right phrenic nerve palsy
Right dome of the diaphragm is higher than the left
paralyzed side is always higher
damage to phrenic nerve
Psoas major
Action: flexes the hip
innervation: ventral rami of L1-L3
Quadratus lumborum
action: depresses and stabilizes rib 12
lateral bending
innervation: ventral rami of T12-L4
Iliacus
action: flexion of the hip
innervation: femoral nerve
Obstructed blood flow of the IVC?
azygos system of veins
internal thoracic veins
axillary vein
alternative pathways
very obvious during physical evaluation
Lymphatics of the posterior abdominal wall?
drain to the lumbar nodes
will eventually drain into the cisterna chyli (L1 +L2)
Function of the sacrospinous and sacrotuberous ligaments?
Oppose posterior sacral rotation
Obturator internus and piriformis
Lateral rotation and abduction
obturator canal
obturator nerve and artery
What makes up the levator ani?
Iliococcygeus
pubococcygeus
Coccygeus
Episiotomy
To prevent excessive damage during child birth the perineal muscles are obliquely cut
Pudendal nerve block
The ischial spine is used as a landmark for the injection
block pain reception in the pudendal and other nerves in the perineal area
