3D Anatomy of Thoracic Muscular System

The muscular system of the thorax comprises muscles involved in respiration and movements of the upper limb. The intercostal muscles, including the external, internal, and innermost intercostals, play a crucial role in breathing. The diaphragm, a dome-shaped muscle, separates the thoracic and abdominal cavities and is essential for respiration. Other significant muscles include the pectoralis major and minor, serratus anterior, and the muscles of the back and shoulder girdle. Detailed 3D models illustrate the origin, insertion, innervation, and function of these thoracic muscles.
