Dissection activities
• Continue dissection of arm muscles
• Dissection of abdominal muscles
– Have to go through thick fascia to get to
rectus abdominis
– External oblique is already visible
• You must CUT through the external oblique
to get to internal oblique and transverse
abdominis
– Check the direction the fibers are running!
