TCVS (Thoracic PT 1)

The document provides an overview of thoracic and cardiovascular anatomy, including the structure and function of the thoracic cage, muscles involved in respiration, and various thoracic surgical procedures. It details the importance of anatomical landmarks for surgical access and describes common conditions and injuries related to the thorax, such as pneumothorax, flail chest, and mediastinal injuries. Additionally, it outlines diagnostic techniques and treatment options for thoracic trauma and related complications.

2. Mammary Line- inner aspect of clavicle, passes thru nipple
3. Parasternal line- lies midway between the midsternal and

7. Scapular line- runs through the apex of the inferior angle of
the scapula
These longitudinal lines are important in describing certain lesions or when
