there are 12 bones in the thoracic column.
The ribs, the thoracic vertebrae and the sternum, some would also consider the clavicle part of the thoracic cage.
Spine. VERTEBREA
No, the acromial region (shoulder) is lateral to the thoracic region (chest).
The bones of the spine are called vertebrae. There are 33 total vertebrae in 5 regions: cervical (7), thoracic (12), lumbar (5), sacral (5), and coccygael (4). (The 5 bones of the sacral region are fused, as are the 4 bones of the coccygeal region.)
The inferior border of the thoracic region is the bottom of the ribs. Thus all the ribs are within the thoracic region, icluding the two flaoting ribs at the bottom.
There are 33 bones in the spinal column. There are five regions in the column. In descending order there is the Cervical region which has 7 bone, Thoracic region which has 12 bones, Lumbar region which has 5 bones, Sacral region which has 5 bones (these bones are fused together), and the Coccygeal region that has 4 bones (these bones are fused together). The coccygeal region can actually have anywhere from 3-5 bones, but the average is 4.
The lungs are surrounded by the bones of the thoracic cage. The thoracic cage consists of the following bones:12 pairs of rib12 thoracic vertebrasternum
There are twelve different bones that known as thoratic vertabrae.
The Thoracic region of the spinal column.
All ribs are attached in the back to the thoracic vertebrae.
The ribs articulate with the thoracic vertebrae.
