The Diaphragm is a dome-shaped musculotendinous sheet separating the thoracic and abdominal cavities. It is convex on it's cranial surface.
The Diaphragm is a dome-shaped musculotendinous sheet separating the thoracic and abdominal cavities. It is convex on it's cranial surface.
In the neutral position between full [[Anatomy & Physiology#Inspiration|inspiration]] and full [[Anatomy & Physiology#Expiration|expiration]], the most cranial part of the Diaphragm is in line with the 6th Rib.

During [[Anatomy & Physiology#Inspiration|Inspiration]], the diaphragm contracts to increase the volume of the thoracic cavity, decreasing it's pressure, thus drawing air in.
