Description
Get the thorax landmarks straight fast. This lesson walks through the thoracic wall, the sternal angle (Angle of Louis) and why it matters, how the mediastinum is divided, the thoracic inlet (suprapleural membrane, Sibson’s fascia), and the diaphragm, including attachments plus major and minor openings with levels (T8, T10, T12). Great for anatomy review and exam prep.
