The twelfth thoracic vertebra has the same general characteristics as the eleventh, but may be distinguished from it by its inferior articular surfaces being convex and directed lateralward, like those of the lumbar vertebrae; by the general form of the body, laminae, and spinous process, in which it resembles the lumbar vertebrae; and by each ...
[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 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 number of vertebrae in a region can vary but overall the number remains the same. In a human spinal column, there are normally 33 vertebrae. [3] The upper 24 pre-sacral vertebrae are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx, or tailbone.
