The thoracic vertebrae are found in the chest region of the body. Humans have twelve thoracic vertebrae which are located between the cervical and lumbar vertebrae.
The part of the skeleton enclosing the thorax, consisting of the thoracic vertebrae, ribs, coastal cartilages, and sternum.
The ribs, the thoracic vertebrae and the sternum, some would also consider the clavicle part of the thoracic cage.
thoracic vertebrae
There are three parts of the spine, the cervical, thoracic and lumbar. Each vertebrae is listed by its number. For example the first 7 vertebrae (from the top) are listed as C1-C7 meaning C for cervical. The thoracic vertebrae starts after C7, the 8th vertebrae is T1-T12, so there is 12 individual vertebraes in the thoracic spine. After the thoracic, is the lumbar which have 5 individual vertebrae, L1-L5.
The cervical bones (1-5) run from the base of the skull to the bottom of the neck, roughly. The thoracic vertebrae (1-12) run from the end of the cervical spine to the lumbar spine. The lumbar vertebrae (1-5) run from the end of the thoracic spine to the tailbone.
The part of the body that has vertebrae is the spine. The spinal column consists of 33 vertebrae which provides support to the body and protects the spinal cord.
The Thoracic Vertebrae have such features and are in the correct position to articulate with the ribs correctly (the cervical vertebra are too high to touch the ribs in the neck region, and the lumbar, sacral and coccyx are all too low to intersect the ribs!)Thoracic Vertebrae
I will like to demonstrate the body of the lumber vertebra. I will simply put my finger on the body of the vertebra and say that this is body. This is pedicle. Then this is lamina. This is spine and and like wise. Then I will put the cervical and thoracic vertebrae for comparison. You will know the facts in no time. Even you write a book on the vertebrae, it will create confusion only. You can see the atlas of the anatomy if bones are not available.
In the cervical and thoracic area of your spine. The cervical vertebrae starts right under your skull (following what's called the occipital foramen/foramen magnum). There are 7 cervical verterbrae and they end aproximatively under your neck (in the place where you feel a small circular prominence). Right under there are the thoracic vertebrae, in the number of 12. They end, let's say, at the upper part of your lower back.
The thoracic duct collects most of the lymph from the body.
