Muscle Spinocostalis Long Inferior

The long inferior spinous costalis muscle (m.spinocostalis longus) is a muscle that is located on the lateral surface of the chest and is involved in the movement of the ribs. It is part of the pectoralis major muscle and consists of several muscle fibers.

The function of the spinoscostalis longus inferioris muscle is to help the pectoral muscles compress the ribs and increase the volume of the chest during inhalation. It also plays an important role in maintaining the correct alignment of the ribs and spine while moving and standing.

The longus spinalis inferior muscle is located on the lateral side of the chest between the lower edge of the scapula and the ribs. It consists of several bundles of muscle fibers that run from the shoulder blade to the ribs.

In the human body, muscle is one of the most important and necessary muscles. Muscles are used to perform various functions such as movement, balance, and defense of the body.

**Muscle spinalis costalis** or thoracolumbar muscle, which is involved in extension and rotation of the body, bringing the humerus closer to the body. It is involved in the breathing process, during which it helps to change the depth of the chest and, as a result, enrich the body with oxygen. It is also actively involved in the work when bending the body forward, bending forward with a load, and deep squats.

**The muscle has the following structure**:

1) The superficial layer consists of smooth muscle, occupying the spaces between the fibers, which are located more densely. 2) The deep layer is represented by fibrous structures, from which several longitudinal tendons extend. They originate in some segments of the lumbar, thoracic
