Intrajugular Processes

Intrajugular processes (processus intrapectorales) are bony outgrowths in the chest area, which are located between the inner surface of the chest and the collarbone. They are part of the rib cage and help maintain its shape and strength.

The intrajugular process consists of two parts: upper and lower. The upper part is on the inner surface of the chest, and the lower part is on the collarbone. The processes are connected to each other by tendons and ligaments, which provide stability and support to the breast.

The functions of the intrajugular processes include supporting the breast and protecting the internal organs. They are also involved in the movement of the arms and shoulders, providing stability and flexibility.

However, some people may have abnormalities in the development of the intrajugular processes, such as their absence or malposition. This can lead to problems with arm and shoulder movement.

Surgery or other correction methods may be required to treat such abnormalities.
