Subcostal Region [Regio Hypochondriaca, Pna, Bna; Pars lateralis (Regio Hypochondriaca), Jna]

The subcostal region is a paired region located on the anterolateral wall of the abdomen. It is limited:

1. Above - costal arch or VII rib
2. Medial - lateral edge of the rectus abdominis muscle
3. Bottom - a horizontal line drawn through the lowest point of the X edge

The subcostal region is located under the costal arch, hence its name. It is part of the lateral wall of the abdomen. This area contains the liver, gallbladder, right kidney, right adrenal gland, and part of the large and small intestine.

The hypochondrium and its functions Features of the structure of the anterior and lateral sections The hypochondrium includes several layers: - Pectoral fascia - Serratus anterior - Vastus dorsi - Extensor dorsi longus ✏ From the border of the lower 9 ribs begins a muscle group of muscles that takes part in the formation of the abdominal wall: transverse muscle, diaphragm, internal oblique muscle. The subcostal region is divided from the upper aperture of the sternum and the intercostal spaces.

*They are paired formations, one side on each rib, located *on the anterolateral surface of the abdomen*. The boundaries are: above - the costal arch or the seventh rib; in front and below - a transverse line through the lower ends of the ribs; medially - line, drawn
