These structures can be observed in Figures 7.28-7.32 VISCERA OF THE MEDIASTINUM Structures of the superior mediastinum Notes Thymus A primary lymphoid organ located in the superior mediastinum. It lies posterior to the manubrium and anterior to the pericardium. After puberty, the thymus is replaced by fat. Trachea Descends anterior to the esophagus. We will examine in more detail in the Lab 13. Esophagus A fibromuscular tube that extends from the laryngopharynx to the stomach. The esophagus lies between the trachea and the vertebral bodies and continues to the posterior mediastinum. It exits the thoracic cavity through the esophageal hiatus of the diaphragm when it continues for a short distance in the abdomen. These structures can be observed in Figures 9.1 and 9.2

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
