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 ...

Jul 26, 2023 · The rectus abdominis muscle is innervated by the thoracoabdominal nerves, which enter the rectus sheath by piercing its anterior surface. They pass between the transversus abdominis and internal oblique muscle layers, and pierce the sheath of …

To quantify the architectural properties of rectus abdominis (RA), external oblique (EO), internal oblique (IO) and transverse abdominis (TrA), and model mechanical function in light of these new data. Knowledge of muscle architecture provides the …

Apr 2, 2019 · The rectus abdominis muscles are a pair of long muscles that run vertically up the front of the abdomen, stretching from the pubis to the xiphoid process. They compress the viscera and tense the abdominal wall.

The rectus abdominis muscle, (Latin: straight abdominal) also known as the "abdominal muscle" or simply the "abs", is a pair of segmented skeletal muscle on the ventral aspect of a person's abdomen (or "midriff").

The rectus abdominis is a prominent paired muscle located in the anterior abdominal wall, forming the "six-pack" appearance in well-defined individuals. Understanding its origin, insertion, muscle path, and function is essential for comprehending its role in human anatomy and movement.

Feb 18, 2024 · The rectus abdominis muscle is strap-like in appearance and forms part of the anterior abdominal wall and is enclosed by the rectus sheath. Summary. origin: pubic symphysis, tubercle and crest. insertion: xiphisternum and 5 th-7 th costal cartilages. action: supports abdominal viscera, compression of the abdomen, trunk movement
