Thorax - transverse section

Transverse section through the thorax (from the Visible Human Project). Note the location of internal organs such as the lungs and the heart, including the differing sizes of the right and left ventricles. Anteriorly, the pectoralis major muscle overlies the rib cage. Laterally attachments of the serratus anterior muscle to the 3rd - 8th ribs, can be seen. Posteriorly, the latissimus dorsi, trapezius and erector spinae muscles may be seen.
