Left kidney

Fundus of gallbladder

Neck of pancreas

Duodenojejunal flexure

SMA
Portal vein

L + R colic flexures

T9

29
Q

The transpyloric plane (of addison) lies at which vertebral level and passes through which structures?

A

L1 - can be approximated by using a hands breath below the xiphoid.

Pylorus
Pancreatic Neck
The duodenojejunal flexure
Fundus of the gall bladder
The tip of the 9th costal cartilage
The hila of BOTH kidneys

It also corresponds to the level of termination of the spinal cord

31
Q

The supracristal plane can be found at which vertebral level?

A

L4 - the summits of the iliac crests and bifurcation of the aorta. (also useful for lumbar puncture as well below end of spinal cord L1)
