Muscles, Transverse Costales Short (M. Transversocostales Breves, Jna)

The transverse costal brevis muscles are a group of muscles that are located in the chest area and help in the movement of the ribs. These muscles play an important role in breathing as they allow the ribs to move during inhalation and exhalation.

The short transverse costalis muscles are also known as the transverse costalis muscles (JNA) or the transverse costalis muscles (M. transversocostalis Breves). They are a group of muscles located between the ribs and the sternum. These muscles consist of several muscle bundles, each of which is responsible for the movement of a specific rib.

When the muscle, the transverse costal brevis, contracts, the rib rises upward, which allows the volume of the chest to increase when inhaling. When the muscle relaxes, the rib returns to its original position, which facilitates exhalation.

In addition, the transverse costal muscles are also involved in body movements and help maintain balance.

Thus, the transverse costal muscles play an important role in maintaining the health of the respiratory system and are an integral part of the normal functioning of the body.
