Each thoracic nerve root exits the spinal canal through a bony hole, called an intervertebral foramen. This bony hole is formed by two adjacent vertebrae, and its size and shape can slightly shift as the vertebrae move.
How are motor and sensory functions determined?
The motor and sensory functions provided by a thoracic nerve root are determined by its vertebral level. While these functions can slightly vary from person to person, they typically are as follows:
Cervical Spine (C1-C7 Vertebrae)
The Cervical spine is made up of 7 vertebrae (known as C1 – C7) that form the neck. The top two bones are known as the Atlas and the Axis. They allow for rotation and tilting of the head.
Thoracic Spine (T1 – T12 Vertebrae)
The Thoracic spine is made up of 12 vertebrae (known as T1 – T12) to which the ribs attach. Since they support more of the body’s weight, they are larger than the cervical vertebrae.
Lumbar Spine (L1 – L5 Vertebrae)
The Lumbar spine is made up of 5 vertebrae (known as L1 – L5) forming the lower back.
Sacrococcygeal (S1 – S5 and Co1 – Co5 Vertebrae)
The Sacrococcygeal is made up of the Sacrum and the Coccyx. The Sacrum is made up of 5 vertebrae (known as S1 – S5) which are fused together and form the base of the spinal column intersecting the pelvis and supporting the upper body (indicated by the lighter yellow portion in the diagram below).
