Describe the sciatic nerve
|
The sciatic nerve (L4, L5, S1, S2, and S3), composed of the common peroneal nerve and tibial nerve, is bound together by fascia. It gives no branches in the gluteal region. In the posterior thigh, the muscular branch (tibial component) supplies the hamstrings (biceps femoris, semitendinosus, semimembranosus and adductor magnus). Halfway down the thigh, the sciatic nerve divides into the tibial nerve and the common peroneal nerve.

Discuss the openings of the Diaphragm
|
Openings in the Diaphragm
diaphragm is pierced by a series of apertures to permit of the passage of structures between the thorax and abdomen. Three large openings — the aortic, the esophageal, and the vena cava — and a series of smaller ones opening level caval T8 structure inferior vena and some branches of the right phrenic nerve esophageal hiatus T10 structure esophagus, the anterior and posterior vagal trunks, and some small esophageal arteries aortic hiatus T12 structure the aorta, the azygos vein, and the thoracic duct remember this mnemonic: Aortic hiatus=12 letters =T12 Esophageal =10 letters= T10 Vena cava = 8 letters = T8 |

Describe thoracentesis
|
Thoracentesis (also known as thoracocentesis or pleural tap) is an invasive procedure to remove fluid or air from the pleural space for diagnostic or therapeutic purposes. A cannula, or hollow needle, is carefully introduced into the thorax, generally after administration of local anesthesia.
This procedure is indicated when unexplained fluid accumulates in the chest cavity outside the lung. In more than 90% of cases analysis of pleural fluid yields clinically useful information. If a large amount of fluid is present, then this procedure can also be used therapeutically to remove that fluid and improve patient comfort and lung function. The most common causes of pleural effusions are cancer, congestive heart failure, pneumonia, and recent surgery. In countries where tuberculosis is common, this is also a common cause of pleural effusions. Insert needle just above rib #9 and not under rib #8 The inferior edge of the scapula lies over the 7th intercostal space Complication: pneumothorax (air in the pleural cavity) |
