Muscle, Iliocostal Lumbar (M. Iliocostalis Lumborum, Pna, Bna)

Muscle, iliocostal lumbar (M. Iliocostalis Lumborum, Pna, Bna)

The muscle, iliocostalis lumborum (M. Iliocostalis Lumborum) is one of the largest muscles of the back, which is located along the spine. It belongs to the deep muscles of the back and plays an important role in maintaining an upright body position, as well as in performing various movements.

M. Iliocostalis Lumborum comes from the upper edges of the four lower ribs and from the lower part of the femur. The muscle then passes upward and backward, expanding and branching along the spine. It ends in the form of a strong tendon plate, which is attached to the last thoracic and all lumbar vertebrae.

M. Iliocostalis Lumborum is divided into three parts: medial (Pars Medialis), intermedial (Pars Intermedius) and lateral (Pars Lateralis). All three parts have their own characteristics and perform different functions.

Pars The medialis is located closer to the spine and is responsible for the expansion of the spine, as well as its lateral tilt. Pars Intermedius is located between Pars Medialis and Pars Lateralis and plays a role in keeping the spine in an upright position. Pars Lateralis is located closer to the edge of the back and is responsible for its rotation.

Together, these three parts of M. Iliocostalis Lumborum form the iliocostal lumbar muscle complex (PNA, BNA), which is one of the main elements of the muscular system of the back.

The muscle, the iliocostalis lumborum (M. Iliocostalis Lumborum, PNA, BNA) plays an important role in maintaining an upright body position and performing various movements. Its different parts perform different functions, allowing it to effectively cope with the various tasks involved in supporting and moving the body.

In general, understanding the anatomy and function of the muscle, iliocostalis lumborum (M. Iliocostalis Lumborum, PNA, BNA) is important for professionals working in the field of medicine, physical therapy, sports and other related fields. A good knowledge of this muscle can help in effective rehabilitation after injury, improving posture and increasing physical fitness.

Iliocostalis lumborum muscle (M. Iliocostalis Lumborum, PNA, BNA): Anatomical overview and functions

The iliocostalis lumborum muscle, also known as M. Iliocostalis Lumborum or PNA (Pars lumborum) and BNA (Pars thoracis), is one of the important muscles of the back that plays a role in maintaining correct posture and is involved in the movement of the spine.

Anatomically, the iliocostalis psoas muscle extends along the side of the spine, starting from the lower edge of the rib cage (ribs) to the upper edge of the lumbar vertebrae and the ilium. It consists of two parts: PNA and BNA.

PNA (Pars lumborum) is located in the lumbar region of the back. It originates from the lower ribs and is inserted onto the lower lumbar vertebrae. The BNA (Pars thoracis) is located in the thoracic region and starts from the upper ribs, extending down to the lower lumbar vertebrae.

The primary function of the iliocostalis psoas muscle is to expand and laterally tilt the spine. When both sides of the muscle work together, they help straighten the spine and maintain posture. When one side of the muscle contracts, it causes the spine to flex laterally.

Along with these functional movements, the iliocostalis psoas muscle is also involved in spinal rotation and stabilization. It works in conjunction with other back and abdominal muscles to promote proper balance and coordination.

In addition to its role in spinal movement, the iliocostalis psoas muscle may also play a role in maintaining abdominal pressure and is involved in breathing.

Training the iliocostalis psoas muscle can be beneficial for strengthening your back and improving your posture. Various exercises such as side bends, spinal rotations and kettlebell exercises can help develop and strengthen this muscle.

In conclusion, the iliocostalis lumborum muscle (M. Iliocostalis Lumborum, PNA, BNA) is an important back muscle that plays a role in maintaining posture, spinal movement, and is involved in rotation and stabilization of the spine. This exercise can be helpful for strengthening your back and maintaining healthy posture. Regular exercise that targets this muscle can help improve posture, reduce the risk of back injuries, and increase overall physical strength.
