Where are the midclavicular planes?
passes from the midpoints of the clavicles to the midinguinal points
What are midinguinal points?
the midpoints of lines joining the ASIS and the superior edge of the pubic symphasis

Where are tendinous intersections typically found?

Where is the median umbilical fold?
extends from the apex of the urinary bladder to the umblicus; covers the median umbilical ligament
