Explain how the tendinous intersections of the rectus abdominis of the cat differ from those found in humans?

The tendinous intersections refer to the three fibrous bands that cross the rectus abdominis muscle. The upper band is located at the xiphoid process, the lower one at the umbilicus level, and the middle one is situated between the two bands. The tendinous intersections in humans are formed of tendinous fibers, which differentiates the rectus abdominis into four components.  

On the other hand, the rectus abdominis muscle is spontaneous in the case of cats, that is, it arises from the pubis and merges with the costal cartilages numbering five to seven and the sternum. The alternate overlapping of the internal oblique and rectus abdominis muscles produces the intersections, however, no true intersections are witnessed in it.
