How does the fiber orientation of the external oblique compare to the internal oblique?
Imagine standing and crossing your arms (i.e. so that your right hand touches your left thigh and your left hand touches your right thigh). This would be considered the fiber direction of your External obliques which are the most superficial abdominal muscles. Deep to the external obliques are your internal oblique muscles. Your internal obliques run mostly perpendicular to your external obliques (i.e. opposite direction). The next layer of the abdominal muscles are the transverse abdominals whose fiber direction is parallel (horizontal) to the ground (when standing).
Hope this helps.

Name a skeletal muscle in the abdomen?

Which abdominal muscles rotate the trunk to the same side?
The right internal oblique and the left external oblique contract as the torso flexes and rotates to bring the left shoulder towards the right hip. The left internal oblique and the right external oblique rotates the right shoulder to the left hip (as in grapping for your seat belt). For this reason, the internal obliques are referred to as "same side rotators."
