Sternal angle

The video lecture by Dr. Morton explores the sternal angle, comparing it to a treasure map's 'X marks the spot.' It explains the anatomical significance of the sternal angle, also known as the angle of Louis, and introduces the mnemonic 'rat plant' to remember key structures found at this location. The lecture further discusses the transverse thoracic plane and its anatomical relevance, detailing structures like the aortic arch, tracheal bifurcation, and more. The lecture concludes with a summary of the key points covered.
