Overkroppens

Overkroppens is a term used in Scandinavian contexts to refer to the upper body. In anatomical and medical descriptions, it denotes the region from the neck to the waist, encompassing the thorax (chest), back, shoulders, and the upper limbs. The lower boundary typically lies at the waist or iliac crest, separating the upper body from the lower trunk. The overkroppens contains the principal structures that support movement, respiration, and protection of vital organs.

Anatomically, the region includes the skeletal framework of the thorax and shoulder girdle: the clavicles, scapulae, sternum, and ribs, along with the upper portions of the vertebral column. The muscles are diverse, including the pectoralis major and minor, deltoids, trapezius, latissimus dorsi, serratus anterior, and the intercostal muscles that assist breathing. Major neurovascular elements pass through or near this region, such as the brachial plexus and the axillary vessels. The thoracic cavity houses the heart and lungs, with portions of nearby upper abdominal organs close to the diaphragm.

Functions of overkroppens include supporting and moving the arms, stabilizing the trunk, enabling respiration, and protecting thoracic organs. Movement involves coordinated action of the shoulder girdle, chest, and back muscles, while breathing relies on rib and intercostal muscle activity.

Clinical relevance covers common injuries and conditions affecting the upper body, such as rib fractures, shoulder and chest wall trauma, thoracic outlet syndrome, and scoliosis. Imaging of the overkroppens frequently uses chest X-ray, CT, or MRI to assess bones, soft tissues, and organ health.
