3D Anatomy model of Abdominal Muscles

The muscular system of the abdomen includes muscles that support the trunk, aid in respiration, and assist in movements and posture. Major muscles include the rectus abdominis, external oblique, internal oblique, and transversus abdominis. The rectus abdominis, commonly known as the “abs,” runs vertically along the anterior wall and is divided by tendinous intersections. The oblique muscles contribute to trunk rotation and lateral flexion. The transversus abdominis, the deepest muscle layer, provides core stability. Detailed 3D models illustrate the origin, insertion, innervation, and function of these abdominal muscles.
