The Diaphragm

This week we explore the primary muscle of respiration that separates the thoracic & abdominal cavities. A muscle that was historically thought of as being the seat of the soul. In this podcast, we will dissect out the diaphragm's form, function, innervation, & blood supply. Whilst also explaining the origin of some of the terms we use to describe diaphragm-related structures.

The terms mentioned this week are the diaphragm and phrenic nerves. Costophrenic and costodiaphragmatic angles. The oesophageal hiatus and caval openings. Crura, the xiphisternum, skeletal muscle & somatic nerves.
