Y1 - 2020 N1 - T2 - Photographic Dissector for Students of Physical Therapy: A Step-by-Step Approach AB - While performing the thoracic cavity dissection, you will be following many of the structures of the neck as they enter through the superior thoracic aperture. Of particular importance is observing the course of the vagus, phrenic, and recurrent laryngeal nerves. The thorax is composed of three enclosed cavities, the mediastinum for the heart, and two plural cavities, one for each lung. As these cavities are enclosed, they depend on movement and reorientation for their drainage. Infections and inflammation, as well as inactivity, can cause a build-up of fluid within these areas.
