Posterior Abdomen Flashcards
Function of posterior abdominal wall
Supports organs
Facilitates respiration
Provides movement at the hip
Where does the retroperitoneal space lie?
In between posterior abdominal wall and peritoneum
Kidneys and Pancreas
retroperitoneal organs
What structures protect the kidneys
ribs
quadratus lumborum
Psoas major
Where do the adrenal veins drain to?
The renal veins
What vein off the IVC needs to travel longer to reach the kidney?
Left renal vein Enters the renal hilum: - renal vein - renal artery - ureter
The adrenal medulla is made up of…
Chromaffin cells
Preganglionic sympathetically go straight to the organ!
The adrenal medulla is like a giant post-ganglionic sympathetic
What drains into the left renal vein?
Left gonadal vein
Left gonadal artery comes off the aorta
- reminds us of the origin of testes on the posterior abd. Wall
Ureter exists in the…
Retroperitoneal space
- muscular ducts that convey urine from the Renal pelvis -> urinary bladder
- courses within retroperitoneal space
Where does ureter naturally constrict at?
- renal pelvis
- crossing the pelvic brim
- entering the bladder
Kidney stones might be lodged here causing FLANK PAIN (loin->groin)
T11-L2 : as the kidney stone moves, the pain moves
What innervates the ureter?
Sympathetic/parasympathetic
Aorticorenal Plexus
Sympa: regulates peristalsis
Parasympathetic: vagus/pelvic sphlanchnic nerve
Transplantation of kidney to the iliac fossa
The renal artery/vein is anastomosed to the common or external iliac fossa
Ureter is made as short as possible:
- must have a good supply, therefore you take the 1st third of the ureter with it
What cervical nerves innervate the diaphragm?
C3, C4, C5
What nerves go to the suprarenal glands?
Greater splanchnic nerve
Lesser splanchnic nerve
Least splanchnic nerve
What is the ganglia to the suprarenal glands?
celiac ganglia
Superior mesenteric ganglia
Aorticorenal ganglia
