The fifth thoracic vertebra, together with the fourth, is at the same level as the sternal angle. The human trachea divides into two main bronchi at the level of the 5th thoracic vertebra, but may also end higher or lower, depending on breathing. The thoracic spinal nerve 5 (T5) passes inferior to it.
The carina of the trachea is located at the level of the sternal angle and the fifth thoracic vertebra (at rest). The right main bronchus is wider, shorter, and more vertical than the left main bronchus, [3] its mean length is 1.09 cm. [4] It enters the root of the right lung at approximately the fifth thoracic
The carina occurs at the lower end of the trachea - usually at the level of the 4th to 5th thoracic vertebra. [3] [4] This is in line with the sternal angle, but the carina may raise or descend up to two vertebrae higher or lower with breathing. The carina lies to the left of the midline, and runs antero-posteriorly (front to back). [citation ...
The trunk of the body contains, from superior to inferior, the thoracic region encompassing the chest [1] the mammary region encompassing each breast; the sternal region encompassing the sternum; the abdominal region encompassing the stomach area; the umbilical region is located around the navel; the coxal region encompassing the lateral (side ...
[2]: 319 The horizontal plane that passes through the sternal angle and the articular disc between the 4th and 5th thoracic vertebrae represents the imaginary boundary between the superior mediastinum and inferior mediastinum. [citation needed] It is located approximately 7 cm inferior to the superior margin of the manubrium. [citation needed]

The rib cage or thoracic cage is an endoskeletal enclosure in the thorax of most vertebrates that comprises the ribs, vertebral column and sternum, which protect the vital organs of the thoracic cavity, such as the heart, lungs and great vessels and support the shoulder girdle to form the core part of the axial skeleton.
The picture displays the mediastinum on sagittal plane, thoracic diaphragm at the bottom, the heart (cor), behind sternum and ribs (to the left on the picture (this is the anterior/front) and to the right (posterior/back)), you have the thoracic vertebrae. The thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is ...
