Diaphragm Anatomy: Structure and Function

This lecture covers the anatomy of the diaphragm, including its three main divisions (sternal, costal, and lumbar), the central tendon, and the various ligaments (arcuate ligaments). It also explains the openings in the diaphragm, such as the esophageal hiatus and aortic hiatus, and the passage of structures like the inferior phrenic arteries and phrenic nerves. The lecture details the attachments of the diaphragm, the role of the phrenic nerves, and the relationships with surrounding structures like the psoas major and quadratus lumborum muscles.
