To the left is the abdomen, where part of the liver and the gall bladder can be seen. The diaphragm is in the middle. To the right is the thorax. The largest object seen in the thorax is the rest of the liver. Just to the right of that is the heart. The liver was connected to itself through a small hole in the diaphragm (not seen). Specialty
Definition of diaphragm in Blount's 1707 Glossographia Anglicana Nova. The diaphragm is an upward curved, c-shaped structure of muscle and fibrous tissue that separates the thoracic cavity from the abdomen. [6] The superior surface of the dome forms the floor of the thoracic cavity, and the inferior surface the roof of the abdominal cavity. [7]
The free edge of a ruptured diaphragm may curl and become perpendicular to the chest wall, a sign known as a dangling diaphragm. A herniated organ may constrict at the location of a rupture, a sign known as the collar sign. If the liver herniates through a rupture on the right side, it may produce two signs known as the hump and band signs.
Bochdalek hernia is one of two forms of a congenital diaphragmatic hernia, the other form being Morgagni hernia.A Bochdalek hernia is a congenital abnormality in which an opening exists in the infant's diaphragm, allowing normally intra-abdominal organs (particularly the stomach and intestines) to enter into the thoracic cavity.
The esophageal hiatus is an oval opening [1] in (sources differ) the right crus of the diaphragm [1] /left crus of the diaphragm, with fibres of the right crus looping around the hiatus to form a sling (upon inspiration, this sling would constrict the esophagus, forming a functional (not anatomical) sphincter that prevents gastric contents from refluxing up the esophagus when intra-abdominal ...
The xiphoid process plays a role in the attachment of many muscles, including the abdominal diaphragm, a muscle necessary for normal breathing. Additionally, it serves as an attachment point for the rectus abdominis muscles , commonly known as the "abs."
The aortic hiatus is a midline [1]: 185 opening in the posterior part of the diaphragm giving passage to the descending aorta as well as the thoracic duct, and variably the azygos and hemiazygos veins. [2] It is the lowest and most posterior of the large apertures. [citation needed]
Congenital diaphragmatic hernia (CDH) is a birth defect of the diaphragm. The most common type of CDH is a Bochdalek hernia; other types include Morgagni hernia, diaphragm eventration and central tendon defects of the diaphragm. Malformation of the diaphragm allows the abdominal organs to push into the chest cavity, hindering proper lung formation.
