Posterior Abdominal Wall and Kidneys Flashcards
Where is the posterior abd wall
Posterior to gastrointestinal tract, spleen and pancreas
Extension of posterior mediastinum
What is in the retroperitoneal space
Posterior abd wall
What is retroperitoneal space bounded by
Posterior =Bones, muscles
Anterior = peritoneum
What passes through retroperitoneal space
Structures between thorax to pelvis, head to abd region, transit region, big vessels
Aorta, nerve plexuses, ivc , sympathetic trunk, lymphatic, lumbar plexus, kidney and suprarenal glands (urinary system)
WHAT ARE BONY BOUNDARIES OF POST ABD WALL
Lumbar vertebrae
Pelvis
Thorax
Describe lumbar vertebrae - bones post abd wall
A
Describe pelvis - Gen - bones post abd wall
Superior aspect of pelvic bone, crest, ilia, pubic symphysis, psis, asis
Describe ilia - pelvis - bones post abd wall
Attached laterally to sacrum (sacroiliac joint)
Upper part of each ilium expand outward wing like area = iliac fossa- forms bone
Describe important landmark of pelvis - bones post abd wall
Anterior superior iliac spine = anterior extremity of iliac bone
Describe pubic symphysis - pelvis- bones post abd wall
Between the 2 pubic tubercles
Describe thorax - bones post abd wall
Costal margin, ribs 11-12, xiphoid process
Describe relationship of ribs of thorax that bound post abd wall and kidneys
Rib 11 is posterior to superior part of left kidney
Rib 12 is posterior to superior part of BOTH kidneys
Describe muscles of post abd wall - medially
Psoas major and minor
Fills space between vertebral bodies and transverse processes of t12 to L5
For hip flexion + iliacus muscle, proximal insertion on femur
What muscle passes under median accurate ligament of diaphragm
Psoas
Describe bursa pain
Psoas major, going out = bursa, can be inflamed = pain when work out a lot
