The thoracic vertebrae are the bony elements of the thoracic spine. These vortices are characterized by their contact surfaces of the ribs ( costal facies ). Humans have 12 thoracic vertebrae. They are numbered from top to bottom. To whom they are after the Latin spelling with Th1 to Th12 (Th = thoracic = belonging to the chest ).
Parts of a thoracic vertebra
- Vertebral body ( corpus vertebrae )
- Two transverse processes ( processus transversus )
- Spinous process ( processus spinosus )
- 2 condyles to top vertebra ( superior articular process )
- 2 articular processes to underlying vertebrae ( inferior articular process )
- Vertebral arch (lamina arcus vertebrae)
- Connection between the vertebral arch and vertebral body ( Pediculus vertebrae)
- Two articular surfaces for the ribs ( costal facies )
The shape and size of the thoracic vertebrae is different, as is the orientation of the articular surfaces and the alignment of the vertebrae in the space itself, the size of the vertebral body absorbs from cranial ( head down) to caudal ( tail down) to.
The spinous processes ( spinous processes ) are the easiest to palpate the back. They overlap like roof tiles down, and are therefore somewhat lower than the respective corresponding vertebral body.
