Which among the following body cavities would have to be opened for the surgical removal of a cancerous lung lobe?
Which among the following body cavities would have to be opened for the surgical removal of a cancerous lung lobe?
The surgeon gets access to the chest cavity through the exposed ribs to remove the lobe. In some cases, a video-assisted thoracoscopic surgery (VATS) is used to do a lobectomy.
What body cavity is the mediastinum in?
thoracic cavity
The mediastinum is a division of the thoracic cavity; it contains the heart, thymus gland, portions of the esophagus and trachea, and other structures.
What two cavities does the mediastinum separate?
The mediastinum completely separates the right and left pleural cavities. As in humans and other mammals the esophagus lies dorsal (posterior) to the trachea and its bifurcation and to the pericardium and ventral (anterior) to the thoracic (descending) aorta (Figure 4.8D.).
Which organs are in the thoracic cavity?
[2] The thoracic cavity contains organs and tissues that function in the respiratory (lungs, bronchi, trachea, pleura), cardiovascular (heart, pericardium, great vessels, lymphatics), nervous (vagus nerve, sympathetic chain, phrenic nerve, recurrent laryngeal nerve), immune (thymus) and digestive (esophagus) systems.
What is the lowest part of the abdominal cavity?
Abdominal cavity, largest hollow space of the body. Its upper boundary is the diaphragm, a sheet of muscle and connective tissue that separates it from the chest cavity; its lower boundary is the upper plane of the pelvic cavity.
What are the boundaries for the thoracic cavity?
The boundaries of the Thoracic Cavity are the Ribs (and Sternum), Vertebral Column, and the Diaphragm. The Diaphragm seperates the Thoracic Cavity from the Abdominal Cavity. Mediastinum – Space between the left and right Pleural Cavities.
Where are the mediastinal tumors located in the body?
Mediastinal tumors are growths that form in the area of the chest that separates the lungs. This area, called the mediastinum, is surrounded by the breastbone in front, the spine in back, and the lungs on each side.
How is surgery used to treat mediastinal masses?
Treatment for mediastinal masses varies depending on the tumor type. Surgery is the most common treatment for thymomas. Doctors can often cure thymomas through surgery alone or with surgery followed by radiation. Some thymomas have thick tissue around them known as a capsule.
What causes a cyst in the middle of the mediastinum?
Pericardial cyst: Pericardial cysts are an uncommon benign congenital anomaly in the middle mediastinum. They represent 6% of mediastinal masses, and 33% of mediastinal cysts. Neurogenic tumor: The most common cause posterior mediastinal tumors arise from nerves. They are usually benign, especially in adults.
Is the mediastinal part of the heart or lungs?
What is the mediastinal? The mediastinal is surrounded by the middle part of the chest, defined by the breastbone in front, the spine in back, and the lungs on each side. The mediastinal contains the heart, aorta, esophagus, thymus and trachea.

What are the major organs of the anterior mediastinum?
The major structures in the anterior mediastinum include: Organs: thymus. Arteries: internal thoracic branches. Veins and lymphatics: mediastinal branches of the internal thoracic vessels, parasternal lymph nodes.
