What does the normal and mirror arrangement of organs in man look like?

Consider the usual arrangement of organs in humans.

The brain is an organ in the form of a mass of nerve tissueis inside the skull. The spinal cord, which consists of the nerves associated with the brain, is located in the vertebral canal. His origin, he takes in the medulla oblongata, stretching to the lower back. The pituitary gland is the gland that is located in the deepening of the base of the skull. This is the arrangement of the organs inside the skull.

Language - the organ, formed from muscles, is contained inoral cavity. The pharynx is located behind the mouth and nose behind. The lower part of it is divided into the larynx and esophagus. Palatine tonsils - a pair of glands located behind the tongue of both sides of the pharynx. Adenoids are the glands of the pharynx located on the back wall at the top, behind the nose. The larynx is the upper part of the respiratory throat, called the trachea. If you look at the location of the neck organs from the outside, a lump is visible on the larynx, called the "Adam's apple". Inside it there are vocal cords.

The thyroid gland is located on the frontneck from both sides of the trachea. The parathyroid glands, in the number of four, measuring roughly the size of a pea, are located behind the thyroid gland behind.

Esophagus - a tube consisting of muscle tissue,she descends from the throat to the stomach. Trachea - the respiratory throat, beginning in the larynx, is divided into two bronchi under the breast. The bronchi are between the trachea and the lungs, connecting them together. The lungs, protected from all sides by the ribs, are in the chest. Thoracic glands adhere to the thorax in front.

In the abdominal cavity is a lot of lifeimportant human organs. The liver is the largest organ, it lies slightly below the diaphragm at the top of the cavity. The gallbladder is a pear-shaped sac of a small size, it is located under the liver. The spleen is under the diaphragm, in the abdominal cavity on the left. The pancreas is located below the stomach in the middle of the cavity.

The stomach occupies a position in the left side of the abdominalcavity, with it are connected to the esophagus and small intestine. A long tube of muscle tissue, called the small intestine, connects the large intestine and stomach. Its length in the elongated state is more than six meters. The large intestine, connected to the thin lower abdominal cavity on the right, reaches the liver, then, bending under the diaphragm, it reaches the abdominal cavity on the left. At the bottom of the cavity, it passes into the rectum, ending with the anus.

The arrangement of the organs makes it possibleplaced in the body and such a useless, but delivering unpleasant sensations during inflammation of the organ, as an appendix. It is connected to the cecum in the abdominal cavity at the bottom right. The kidneys are located on both sides of the spine below the rib area in the back of the abdominal cavity. The adrenal glands lie on the kidneys. Ureters connect the kidneys and the bladder, which is located in the lower part of the abdominal cavity. It starts the urethra.

The heart is a hollow organ, dividing into four compartments, consisting of muscles, continuously contracting and relaxing. This organ is located below the sternum in the thorax.

The normal arrangement of organs is called situssolitus. There is also a phenomenon of transposition of internal organs, in which they are located in the mirror. The transposition, or the mirror arrangement of the organs, looks like this: the apex of the heart is turned to the right (it is mostly on the right at the same time). The liver is located on the left, the stomach is on the right.

Mirror arrangement of organs occurs no more often than one person in ten thousand.
