Anatomy Flashcards
What’s this?
Retroperitoneal space
Identify those 4 strucutres
What’s that?
Peritoneum
What’s that?
Fibrous Renal capsule: Completely invest kidneys
What’s that?
Perirenal (Perinephric) fat: extraperitoneal fat, Outside renal capsule surrounding the kidneys
What’s that?
Renal Fascia (Gerota’s):
Membranous fat condensation,
Surrounds each kidney & suprarenal gland,
Enclosing perirenal fat.
What’s that?
Perirenal (Perinephric) fat: extraperitoneal fat, Outside renal capsule surrounding the kidneys
What’s that?
Transversalis fascia
Where are kidneys located?
General Location:
Retroperitoneal
Ant. to quadratus lumborum,
Lat to psoas,
Under diaphragm
Left Kidney: Ant to rib 11 & 12
Vertebral level of T12 to L2
Lies post to spleen, tail of pancreas, left colic flexure
Right Kidney: Ant to rib 12
Vertebral level of L1 to L3
Post to liver, descending portion of duodenum,
right colic flexure
What’s the arterial supply of the kidneys?
Renal A. from abdominal aorta (L1-L2)
Right renal: longer, passes under IVC
Accessory renal a. (common) do not enter via hilum
What’s the venous drainage of the kidneys?
Renal veins from IVC, anterior to Arteries
Left renal vein is longer, passes under SMA, receives left adrenal & gonadal V.
What’s the innervation of the kidneys?
Renal plexus from celiac plexus
Found along renal arteries
•Sympathetic: triggers vasoconstriction
reducing renal blood flow
•Parasympathetic: not well understood.
Why does the kiney necroses if one part of its arterial supply is blocked?
Because it is composed of terminal arteries
What are the 3 points of constriction of the ureter?
- Ureteropelvic junction (junction renal pelvis / ureter)
- Crosses iliac vessels (at the pelvic brim)
- Traverses bladder wall (intramural part)
What’s the urine pathway?
- Renal Papilla
- Minor Calyx
- Major Calyx
- Renal Pelvis
- Ureter
- Bladder
- Saint-Laurent
