Umbilical Region [Regio Umbilicalis, Pna, Bna; Pars (Regio) Umbilicalis, Jna]

The umbilical region (Regio umbilicalis) is the middle region of the abdomen, bounded above by a line connecting the lowest points of the cartilages of the ribs, and below by the interspinous line. From the sides it is limited by vertical lines running along the edges of the rectus abdominis muscles, which provide movement of the torso.

The umbilical region is important for human health as it contains important organs and structures. In particular, the umbilical vessels and umbilical vein are located here, which provide blood and nutrients to the fetus during pregnancy. Also in the umbilical region are the umbilical ring, umbilical artery and umbilical muscles, which help maintain the correct position of the fetus in the uterus.

In addition, in the umbilical region there is the umbilical gland, which is responsible for the production of hormones and regulation of metabolism. It also plays an important role in the development of the immune system.

An important aspect of the anatomy of the umbilical region is its relationship with other areas of the body. Thus, nerves and vessels pass through the umbilical region, which connect it to internal organs such as the liver, spleen and kidneys. In addition, the intestines pass through the umbilical region, which allows for the absorption of nutrients and the removal of waste from the body.

Overall, the umbilical region is an important anatomical region that has many functions and interactions with other organs and systems of the body. Knowing its anatomy and functions can be helpful in understanding the health and functioning of the body as a whole.

Umbilical region. Regio umbilicalis.

The umbilical region is the most important anatomical region that is associated with the development of the fetus during intrauterine development. It is located on the border between the middle and upper abdomen. This is the area where the umbilical vessels and central nervum are located. The navel is an important part of the body and is needed to perform important functions.

Borders: lower line running along the interspinous lines of the X ribs; the upper horizontal, passing through the upper ends of both rectus muscles (ribs) of the abdomen; lateral vertical lines running along the rectus abdominis muscle. The rectus sheath forms a kind of ligament (lig. pubicum, PNA, BNA, JNA), which is attached at the pubic tubercle and continues downward in the form of a connective tissue membrane - a thin layer of peritoneum (tunica serosa) covering the navel.
