Final answer:
The lighted scope used for viewing the mediastinum, trachea, and major vessels of the mediastinum is a bronchoscope. This device falls under the broader category of endoscopes, which are used for internal examinations and procedures.
Step-by-step explanation:
The correct answer to the question about the lighted scope used to visualize the mediastinum, trachea, and the major vessels of the mediastinum is c) Bronchoscope. A bronchoscope is specifically designed for exploring the trachea and the larger air passages of the lungs, which are all situated in the mediastinum. The mediastinum is the central compartment of the thoracic cavity that contains the heart, trachea, esophagus, and major blood vessels
Medical professionals use various types of endoscopic devices to explore internal organs and body cavities. The device, called an endoscope, is a flexible tool that transmits light down fiber bundles to illuminate internal parts, while the reflected light is transmitted back out to be observed by the clinician. It can also have channels for surgical instruments to perform procedures like biopsies or polyp removal. The term endoscope includes various kinds of scopes, such as arthroscopes for joints, and laparoscopes for abdominal cavities.
