Anatomy Mnemonics : Abdomen

Diaphragm innervation
"3, 4, 5 keeps the diaphragm alive":
Diaphragm innervation is cervical roots 3, 4, and 5.

Spleen: dimensions, weight, surface anatomy
"1,3,5,7,9,11":
Spleen dimensions are 1 inch x 3 inches x 5 inches.Weight is 7 ounces.It underlies ribs 9 through 11.

Oblique muscles: direction of externals vs. internals
"Hands in your pockets":
When put hands in your pockets, fingers now lie on top of external obliques and fingers point their direction of fibers: down and towards midline.
· Note: "oblique" tells that must be going at an angle.· Internal obliques are at right angles to external.

Duodenum: lengths of parts
"Counting 1 to 4 but staggered":
1st part: 2 inches2nd part: 3 inches3rd part: 4 inches4th part: 1 inch

Murphy's point organ [for Irish]
"Murphy was an Irishman (and Murphy is a classic Irish surname), and Ireland=green":
Green organ in body is gallbladder, so Murphy's point is the gall bladder.

Meckel's diverticulum details
2 inches long.2 feet from end of ileum.2 times more common in men.2% occurrence in population.2 types of tissues may be present.
· Note: "di-" means "two", so diverticulum is the thing with all the twos.

Leino- definition
"Leino" rhymes with "spleen-o":
Therefore leino- means something to do with the spleen.

Kidney hilums at transpyloric plane [L1]
L-1 goes through hilum of only 1 kidney, and it's the Left one.

Diaphram aperatures: spinal levels
"Come Enter the Abdomen:Vena Cava [8]Esophagus [10]Aorta [12]

Liver inferior markings showing right/left lobe vs. vascular divisions
There's a Hepatic "H" on inferior of liver. One vertical stick of the H is the dividing line for anatomical right/left lobe and the other vertical stick is the divider for vascular halves. Stick that divides the liver into vascular halves is the one with vena cava impression (since vena cava carries blood, it's fortunate that it's the divider for blood halves).

Liver: side with ligamentum venosum/ caudate lobe vs. side with quadrate lobe/ ligamentum teres
"VC goes with VC":

The Venosum and Caudate is on same side as Vena Cava [posterior]. Therefore, quadrate and teres must be on anterior by default.

Autonomics to the gut
"The PARAsympathetics follow a rule of TWO" [pair = two]:

· The vagus does the top, the sacral splanchnics the outflow tract.

"The sympathetics follow a rule of threes":· Greater, lesser, least splanchnic nerves go to the celiac,superior and inferior mesenteric ganglion.
