överkroppens

Överkroppens, in anatomical terms, refers to the upper portion of the human torso, including the head and neck, the thorax and upper back, the shoulders, and the upper limbs. The lower boundary is typically the diaphragm, separating the thoracic cavity from the abdomen. The upper body houses vital structures such as the heart and lungs and supports a wide range of movements through the shoulder girdle and arms.

The skeletal framework of the upper body includes the clavicles (collarbones), scapulae (shoulder blades), sternum, and ribs that form the thoracic cage, along with the vertebral column of the upper back and neck. The humerus in each arm articulates with the shoulder girdle at the glenohumeral joint, enabling a broad range of arm movements.

Muscles of the överkroppen are organized into groups that facilitate movement, posture, and respiration. Major muscles include the pectoralis major and minor in the chest, the latissimus dorsi and trapezius in the back and shoulders, and the deltoids covering the shoulder. The intercostal muscles assist breathing, while the serratus anterior and other muscles stabilize the scapula during arm motion.

The upper body also contains crucial nerves and vessels, such as the brachial plexus that innervates the upper limb, and the subclavian and carotid arteries that supply blood to the thorax and arms. Clinically, the överkroppens is a focus in fields ranging from orthopedics and sports medicine to thoracic surgery and physiotherapy, with common concerns including shoulder injuries, thoracic cage disorders, and postural issues.
