Though this cut refers to the human sub- ject, the relations of parts are substantially the same in the dog. In addition to the pericardium and its contents the middle mediast Archive image from page of Cunningham's Text-book of anatomy The visceral pericardium is as firmly adherent to the heart as is the visceralpleura to the lung.

The visceral pericardium in this situation is also known as the epipericardium. Within the pericardium, the ascending aorta and the pulmonary artery are firmly unitedby connective tissue and surrounded by a common sheath of visceral pericardium. On the left side the posterior mediastinal pleura passes from the lateral aspect of the bodies of the vertebrae on to the left side of the aorta.

Hence, to evacuate pus from the posterior mediastinum, there is less. Anatomy, descriptive and applied. The superior mediastinum Fig. Cardiacus Superior. On the left side the course of the nerve is similar in the neck, but in the superior mediastinum it passes between the left carotid and subclavian arteries, and over the aortic arch, to join with the inferior cervical cardiac branch of the vagus in the formation of the superficial cardiac plexus.

In their course both nerves form co. Die descriptive und topographische Anatomie des Menschen. Sie liegt am Halse hinter der Trachea, etwas links von ihr; im hinteren Mediastinum von der Bifurcationsstelle der Trachea an, an der rechten Seite der Aorta, kreuzt sich weiter unten mit dieser und gelangt durch das links liegende Foramen oesophageum des Zwerchfells zum Magen.

Those of the lower spaces, on each side, form a descending trunk which passes through the aortic opening of the diaphragm and ends in the cisterna chyli. The lower group consists of 3 or 4 glands, and is situated, pos- terior to the ster- num, in the lower part of th e anterior mediastinum. It receives afferents from immediately adjacent parts and from the liver and the diaphr.

The ventral Ues between thesternum and the pericardium and contains some lymph nodes,branches of the internal mammary artery and areolar tissue. The middle portion is the largest and is bounded by the pericar-dium. Its contents are the pericardium, heart, roots of the greatvessels and the phrenic nerves. The dorsal mediastinum lies behind the pericardium. Its contentsare the descending thorac A manual of anatomy.

Clinicians are in the habitof subdividing this space into the superior, anterior, middle, and posteriormediastinum or mediastinal spaces.

The age of an individual and the location of a mediastinal mass are important in considering a diagnosis. In children, mediastinal masses occur most often in the posterior mediastinum and are often benign noncancerous. In contrast, mediastinal masses in adults are more common in the anterior mediastinum and often malignant cancerous. Some causes of mediastinal masses based on location include:.

It's important to note that there are many more causes of abnormalities in the mediastinum, and most often further testing is needed to define the exact cause. The mediastinum may also be included in names of conditions involving this region, such as:. With cancers such as lung cancer and lymphomas, doctors often evaluate the mediastinum to see if any cancer has spread to this region. One procedure that allows surgeons to visualize this area is called a mediastinoscopy.

If a cancer has spread to nodes in the mediastinum, it is often treated differently than a cancer that has not spread to this region; the presence of mediastinal lymph nodes is important in the staging of lung cancer.

Mediastinoscopy was a common procedure for those diagnosed with lung cancer, but the same information may sometimes be available now via a PET scan. Examples: Joy had a procedure done to see if her lung cancer had spread to lymph nodes in her mediastinum.

The mediastinum is located inside the thoracic cavity the chest area between the lungs. It is divided into four compartments: the superior, anterior, middle, and posterior. Each one houses different structures such as the heart and arteries. The heart is located within the middle mediastinum, alongside many blood vessels and lymph nodes. The middle mediastinum is its largest compartment.

The posterior mediastinum houses the esophagus, the descending thoracic aorta, veins, and nerves. Sign up for our Health Tip of the Day newsletter, and receive daily tips that will help you live your healthiest life. Staging lymph node metastases from lung cancer in the mediastinum. J Thorac Dis.
