The abdomen is the area from the diaphragm to the field of thorns hipbone. Creates abdominal (peritoneal cavity), which is delimited by the back side of the spine and muscle, both backbone and knapsack.

Front and side borders of the abdominal cavity is ensured by the muscular layer. It consists of three muscle groups

Front (ventral)

  • direct abdominal muscle (rectus abdominis), which is divided in the midline fibrous band – linea alba,
  • pyramidal muscle (musculus pyramidalis)

Side (lateral) – these muscles are flat, wide and arranged in layers, among them

  • external abdominal oblique muscle (m. obliquus externus abdominis)
  • internal oblique muscle (m. obliquus internus abdominis)
  • transversal abdominal muscle (m. transversus abdominis)

The back (dorsal) – muscles associated with the spine, back, ie. A square lumbar muscle (m. Quadratus lumborum).

The abdominal wall is weak points, the risk for the development of hernias (hernia), for example. Inguinal canal (canalis inguinal) area umbilical scars (umbilicus), weakness in the side and rear – trigone Lumbala.

Distribution of the abdominal cavity
The peritoneal cavity – is lined with peritoneum (peritoneum)
Extraperitoneal cavity – an area without peritoneum, here is the area retroperitoneal (for peritoneal, found in the kidneys, adrenal glands, ureters – ureter, pancreas – pancreas, duodenum and part – duodenum …)
Peritoneum – the peritoneum is a thin, shiny membrane lining the abdominal cavity, the area is about 1,5-2m2. The membrane is capable of forming and secreting as well as absorb different substances in the abdominal cavity. This makes it possible to use peritoneal dialysis for the removal of toxic substances.

we distinguish

  • parietal section – the wall, covers the walls of the abdominal cavity,
  • visceral – organ, covering various organs in the abdominal cavity.
    The transition between the two parts of what is called the peritoneum. Duplications (předstěny). Peritoneum forms and folds vklesliny well.

Abdominal organs

  • Stomach (Gaster)
  • Spleen (lien)
  • Liver (hepar)
  • Gallbladder (vesica billiards)
  • Small intestine – the duodenum (duodenum), jejunum (jejunum), hip (ileum)
  • Large intestine – colon
