Middle layer of the abdominal ...
Other Terms: Intermediate layer of lateral abdominal muscles
The middle layer of muscle in the abdominal wall consists of a few named muscles, of which the internal oblique is the largest contributor. In addition to the large internal oblique muscle sheet, there are small sets of muscle fibers that develop from this plane – a series of lumbar intertransversarii muscles and the fibers of the cremaster muscle in the male. As in other body wall regions this muscle plane is superficial to the major vessels and nerves of the abdominal body wall.
