Where does the true pelvis begin and run? | Begins at the pelvic brim and extends inferiorly to the the level of levator ani |
True or false: The pelvic cavity is inferior to levator ani | False. It is superior |
Perinium is inferior or superior to levator ani? | Inferior |
Name muscles betwen quadratus lumborum and vertebral column | Psoas major, psoas minor |
What part of the body does the psoas major allow you to flex? | Your hip |
True or False: Psoas major and minor have a fascial wrapping called psoas sheath | True |
Where does the psoas sheath extend? | From the lumbar vertebrae all the way to the thigh |
What can tuberculosis of one of the lumbar vertebrae cause pus to flow? | Inferiorly into psoas sheath and appear below the inguinal ligament |
True or false: The right kidney hilum is one vertebra higher than the left | False. The left kidney is one vertebrae higher |
Where is the 12th rib in relation to kidneys? | 12th rib is in the middle of left kidney and along superior border of right kidney |
True or false: The ureter almost never crosses the common iliac artery | True |
Where does the ureter enter the pelvic brim? | Anterior to the bifurcation of the common iliac into the external iliac and internal iliac arteries |

What do you find on the posterior side of each kidney? | T12 and L1 branches |
What are the two branches that L1 give out? | Iliolumbar and ilioinguinal |
What vein do the renal veins go into? | The inferior vena cava |
Where do the renal arteries come off the aorta? | Just below the superior mesenteric artery |
Where is the projection of the umbilicus? | At L4 |
What are the kidneys packed with? | Cushions/layers of fat, then enclosed with renal fascia |
What are the 2 layers of fat around the kidney? | 1 between the renal fascia and kidney capsule(perirenal fat) 1 between the renal fascia and the thoracolumbar fascia(pararenal fat) |

Describe the renal pyramids and what they consist of | Consist of loops of henle, the ductile exiting with urine on the surface of the renal papilla |
Where do the renal papilla pour urine? | Into the minor calyces |
Describe the route in kidney starting from renal papilla | Renal papilla to minor calyx to major calyx to renal pelvis to ureter |
Describe renal sinus | Where there is packing of fat (deep to hilum) where things go in and out |
What artery runs into the splenorenal ligament? | the splenic artery which supplies the spleen |

True or False: Both suprarenal veins drain into renal vein | False. Only left |
What are the sections of the suprarenal glands? | Medulla and Cortex |
What does medulla do? cortex? | Medulla: secretes adrenaline and epinephrine. responds to sympathetic stimulation. Cortex: makes steroid hormones. responds to adrenocorticotropic hormone release by pituitary gland |
