Anterolateral Abdominal Wall and Inguinal Canal Flashcards
bones of the abdomen
lumbars, os coxa (illiac crest and illiac spine)
bones of the os coxa
ilium, pubis, ischium
Regions of the abdomen
midclavicular plane, subcostal plane, transtubercular plane
midclavicular plane
midpoint of the clavicles to the mid inguinal point
subcostal plane
across inferior border of 10th costal cartilage
transtubercular plane
passes through the iliac tubercles on each side and across the body of L5
quadrants of the abdomen
median plane, transumbillical plane, umbillicus
median plane
longitudinal line that separates the body into right and left halves
transumbilical plane
transverse line that passes through the umbilicus - which is approximately between L3 and L4
umbilicus
circle around the belly button
superficial landmark of the appendix, what and where
McBurney’s Point: located about 2/3 between the umbilicus and ASIS
2 layers of superficial fascia in the abdominal wall
Camper’s and Scarpa’s fascia
camper’s fascia
more superficial, fatty layer
scarpa’s fascia
deep to camper’s fascia, more membranous layer
the truly anterior muscle of the abdomen
rectus abdominus
the three lateral (flank) muscles of the abdomen
external oblique, internal oblique, and transversus abdominus
innervation of the four abdominal muscles
segmental; ventral rami of T6-T12, L1
action of all four abdominal muscles
compress and support abdominal viscera
what muscles are responsible for flexing and rotating the trunk
external and internal obliques
