Rectus abdominis muscle
(Redirected from Musculus rectus abdominis)
Rectus abdominis muscle is a muscle that runs vertically on each side of the anterior wall of the human abdomen. It is also known as the "abdominal muscle" or "abs", and is a paired muscle running vertically on each side of the anterior wall of the human abdomen.
Anatomy[edit | edit source]
The rectus abdominis muscle is crossed by three fibrous bands called the tendinous intersections. This is what gives the abdomen its "six-pack" appearance. The muscle is enclosed in the rectus sheath, which is formed by the aponeuroses of the lateral abdominal muscles.
Function[edit | edit source]
The main function of the rectus abdominis muscle is to move the body between the ribcage and the pelvis. Other functions include maintaining posture and respiratory function.
Clinical significance[edit | edit source]
Injury to the rectus abdominis muscle can result in a hernia. This is a condition where the muscle tears and the internal organs push through the tear. This can be very painful and require surgery to repair.
