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

Consider the usual arrangement of organs in humans.

The brain - the organ in the form of a mass of nerve tissue - is located 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 location of the organs inside the skull.

Language - the organ, formed from muscles, is contained in the oral 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 are the vocal cords.

The thyroid gland is located on the front of the neck 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.

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

In the abdominal cavity are many vital organs of man. 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 part of the abdominal cavity, with the esophagus and small intestine connected to it. 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, reaches the abdominal cavity on the left. At the bottom of the cavity it passes into the rectum, ending with the anal opening.

The arrangement of the organs makes it possible to be placed in the body and to such a useless, but unpleasant sensation in the period of 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. The 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 chest.

The normal arrangement of organs is called situs solitus. There is also a phenomenon of transposition of the internal organs, in which they are located in the mirror. Transposition, or mirror arrangement of organs, looks as follows: the tip of the heart is turned to the right (it is mostly on the right). The liver is located on the left, the stomach is on the right.

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