They are the smaller, lighter vertebrae of your neck. Thoracic spine: The next 12 vertebrae run from your neck down your mid-back. Each forms a joint with your 12 pairs of ribs. Lumbar spine: From your ribs to your sacrum, the lower five vertebrae comprise the lumbar spine.

Is lumbar and thoracic the same?

Thoracic (mid back) - the main function of the thoracic spine is to hold the rib cage and protect the heart and lungs. The twelve thoracic vertebrae are numbered T1 to T12. The range of motion in the thoracic spine is limited. Lumbar (low back) - the main function of the lumbar spine is to bear the weight of the body.

Where are the cervical thoracic and lumbar vertebrae located?

Cervical vertebra, lateral view: The lateral view of a typical cervical vertebra. The twelve thoracic vertebrae are located inferiorly to the cervical region. They are larger than the cervical vertebrae and increase in size moving inferiorly to the lumbar region.

What distinguishes thoracic vertebrae from other vertebrae?

Distinguishing features of the thoracic vertebrae include the presence of facets on the sides of the bodies for articulation with the heads of the ribs, and facets on the transverse processes of all, except the 11th and 12th vertebrae, for articulation with the tubercles of the ribs.

What parts of the body are controlled by the thoracic spine?

The thoracic spine has 12 nerve roots (T1 to T12) on each side of the spine that branch from the spinal cord and control motor and sensory signals mostly for the upper back, chest, and abdomen. The thoracic spine (highlighted) spans the upper and mid-back.

Where is the thoracic and lumbar spine?

The thoracic spine sits between the cervical spine in the neck and the lumbar spine in the lower back. Collectively, these three sections make a tower of 24 bones that gives the body structure and houses the spinal cord. The spinal cord and its nerves facilitate communication between the body and the brain.
