Muscle, Rhomboid Minor (M. Rhomboideus Minor, Pna, Bna; M. Rhomboides Minor, Jna)

The rhomboid minor muscle is a small muscle in the front of the chest that helps with breathing. It is located between the collarbone and the sternum, and its function is to expand the chest during inhalation.

The rhomboid minor muscle has three heads: long, short and wide. The long head starts from the collarbone and passes through the front of the sternum. The short head starts from the sternum and passes through the back of the sternum to the ribs. The broad head starts from the ribs and extends to the sternum.

The work of the rhomboid minor muscle is regulated by the nervous system and is regulated by the respiratory center in the brain. When we breathe, the muscle contracts and expands the rib cage, allowing air to pass through the lungs.

In people with lung diseases such as asthma or chronic obstructive pulmonary disease (COPD), the rhomboid muscle may be weakened. This can lead to difficulty breathing and poor overall health.

In addition, people who engage in sports that involve lifting weights may experience damage to the rhomboid muscle. This is because when performing weight lifting exercises, the muscle can be overloaded and injured.

Overall, the rhomboid muscle is an important part of the human respiratory system, and its health can affect quality of life. Therefore, it is important to monitor her condition and take care of your health.
