What vertebrae does the diaphragm attached to?
One can find the origins of the diaphragm along the lumbar vertebrae of the spine and the inferior border of the ribs and sternum. The superior diaphragm origin is continuous from the xiphoid process anteriorly to lower 6 costal cartilages of the thorax laterally and first 2 lumbar vertebrae posteriorly.
Where does diaphragm attach?
Origin and insertion. The diaphragm is a musculotendinous structure with a peripheral attachment to a number of bony structures. It is attached anteriorly to the xiphoid process and costal margin, laterally to the 11th and 12th ribs, and posteriorly to the lumbar vertebrae.
What passes through the diaphragm at T10?
Oesophagus (10 letters) – Passes through the diaphragm at T10. Aortic Hiatus (12 letters) – Descending aorta passes through the diaphragm at T12.
What connects to the diaphragm?
There is a close link between the diaphragm and the thoracic outlet. With reference to neurology, the phrenic nerve along its pathway anastomoses with the vagus, while the vagus runs through the crural region of the diaphragm, innervating this area.
Is the diaphragm connected to the lungs?
What is the diaphragm? The diaphragm is a muscle that helps you inhale and exhale (breathe in and out). This thin, dome-shaped muscle sits below your lungs and heart. It’s attached to your sternum (a bone in the middle of your chest), the bottom of your rib cage and your spine.
Are there two diaphragms?
The diaphragm should be viewed as two distinct muscles, crural and costal, which act in synchrony throughout respiration. However, the activities of these two muscular regions can diverge during certain events such as swallowing and emesis.
What ribs attach to the diaphragm?
The muscles of the diaphragm arise from the lower part of the sternum (breastbone), the lower six ribs, and the lumbar (loin) vertebrae of the spine and are attached to a central membranous tendon.
What passes through caval hiatus?
The caval opening is a hiatus in the diaphragm of humans through which passes the inferior vena cava, the wall of which is adherent to the margins of the opening, and some branches of the right phrenic nerve.
What passes through esophageal hiatus?
In human anatomy, the esophageal hiatus is an opening in the diaphragm through which the esophagus and the vagus nerve pass.
What is the main function of diaphragm?
The diaphragm is a muscle that helps you inhale and exhale (breathe in and out). This thin, dome-shaped muscle sits below your lungs and heart.
What causes a raised diaphragm?
[1] Elevated hemidiaphragm occurs when one side of the diaphragm becomes weak from muscular disease or loss of innervation due to phrenic nerve injury. Patients may present with difficulty breathing, but more commonly elevated hemidiaphragm is found on imaging as an incidental finding, and patients are asymptomatic.
How does the musculotendinous junction affect the muscle?
The connection between a muscle and its tendon. The junction contains muscle cells with sarcomere membranes, which are folded inwards in a complicated manner. The in-folding reduces the ability of the muscle cells to generate stress on the junction during a muscle action, possibly reducing the risk of tears.
What is a musculotendinous tear of the infraspinatus?
The major abnormality is a gross musculotendinous tear of infraspinatus. It is almost complete. Considerable fluid within the defect and surrounding soft tissue swelling. The supraspinatus tendon is also abnormal. It is swollen and contains a full thickness tear posteriorly.
How is the diaphragm attached to the lumbar vertebrae?
The diaphragm is a musculotendinous structure with a peripheral attachment to a number of bony structures. It is attached anteriorly to the xiphoid process and costal margin, laterally to the 11th and 12th ribs, and posteriorly to the lumbar vertebrae. The posterior attachment to the vertebrae is by tendinous bands called crura.
Are there tears to the Mt junction of the subscapularis?
We present the cases of two young and active patients with tears to the MT junction of the subscapularis, highlighting the difficulty of clinical diagnosis, visualization on diagnostic imaging and under arthroscopy, and the implications of decision making for treatment modalities.
