Abdominal muscles cover the anterior and lateral abdominal region and meet at the anterior midline. These muscles of the anterolateral abdominal wall can be divided into four groups: the external obliques , the internal obliques , the transversus abdominis , and the rectus abdominis .
The external oblique is situated on the lateral and anterior parts of the abdomen. It is broad, thin, and irregularly quadrilateral, its muscular portion occupying the side, its aponeurosis the anterior wall of the abdomen. In most humans, the oblique is not visible, due to subcutaneous fat deposits and the small size of the muscle.
The linea alba (Latin for: white line) is a strong fibrous midline structure [1] of the anterior abdominal wall [2] situated between the two recti abdominis muscles (one on either side). The umbilicus (navel) is a defect in the linea alba through which foetal umbilical vessels pass before birth. [1]
The two oblique muscles are the internal and external obliques. They're important for core stability and a slimmer waist. Try the 9 best oblique exercises.
Clavicular head: anterior surface of the medial half of the clavicle. Sternocostal head: anterior surface of the sternum, the superior six costal cartilages, and the aponeurosis of the external oblique muscle: Insertion: Lateral lip of the bicipital groove of the humerus (anteromedial proximal humerus) Artery: Pectoral branch of the ...
The rectus sheath (also called the rectus fascia [1]) is a tough fibrous compartment formed by the aponeuroses of the transverse abdominal muscle, and the internal and external oblique muscles. It contains the rectus abdominis and pyramidalis muscles, as well as vessels and nerves.
The origin of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion. [14] For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm. When this muscle contracts, normally the arm moves due to having less mass than the torso.
The aponeurosis of the abdominal external oblique muscle is a thin but strong membranous structure, the fibers of which are directed downward and medially.. It is joined with that of the opposite muscle along the middle line, and covers the whole of the front of the abdomen; above, it is covered by and gives origin to the lower fibers of the pectoralis major; below, its fibers are closely ...
