Thoracic Diaphragm
Author: Daniel Simões Lopes
Date: 2008
Description: The thoracic diaphragm is a thin, flat, and modified half-dome of musculofibrous tissue that separates the abdominal and thoracic cavities. Directly linked to respiration, the diaphragm is a skeletal muscle that contracts during inspiration, whereas expiration is generally a passive process. A number of different structures cross the diaphragm, but three distinct apertures allow the passage of the aorta, esophagus, and vena cava. Using image data obtained from the Visible Human Project of the 59 year old female cadaver, the 3-D geometry of the diaphragm is reconstructed and, from the corresponding solid model, a shell finite element mesh is generated which is used to perform structural analyses.
