MUSCLE DISSECTION TECHNIQUES

Dissect: to expose the entire length of the muscle from origin to insertion. Most of the procedures are accomplished with blunt probes used to separate various connective tissues that hold adjacent structures together. It does not mean to remove or to cut into the muscles or other organs.

Transect: to cut through the muscle near its midpoint.

The cut is perpendicular to the muscle fibers.

Reflect: to lift a transected muscle aside to expose deeper muscles or other organs.
