Abdominal muscles (cat)

There are four abdominal muscles in the cat, namely, External Oblique, Internal Oblique, Transversus abdominis, and the Rectus Abdominis.

Internal Oblique

This muscle is the innermost abdominal muscle. Origin, second sheet of the lumbodorsal fascia and the pelvic girdle. Insertion, linea alba, Action, compressor of the abdomen.

To see this muscle, first remove the extensive aponeurosis situated on the ventral surface of the cat. Its fibers are extremely longitudinal, on each side of the linea alba. It is also traversed by the inscriptiones tendinae, or what others call myosepta.
