4 main abdominal muscles: Superficial to DEEP
SUPERFICIAL

internal oblique
rectus abdominis
transversus abdominis
DEEP
external oblique
outermost muscles on each side of rectus abdominis
external oblique muscles extend from
lower ribs to pelvis
internal oblique direction
opposite external oblique
rectus abdominis
6 pack
linea alba
connective tissue separating the muscles on each side of rectus abdominis
transversus abdominis
wraps around spine for protection and stability
what encircles the rectus muscle
rectus sheath
where does the rectus sheath extend
to the external oblique, internal oblieuq, and transversus abdominis

lesser trochanter of femur
which muscle is missing? in how many people?
psoas minor
40-70%
