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).
Supination vs. pronation: which is more powerful Screws were
designed to be tightened well by majority of people.
“Righty tighty”: to tighten screws you turn to the right.
