On the other hand, orthotics are a functional device, designed to correct and optimize our foot function. Some insoles also feature an arch support, however they tend to be mostly made of soft materials. As a result, the support they provide is often too weak to have any effect.
Vertebrae and Cervical Spinal Nerves. The cervical spine (sometimes abbreviated as c-spine in the medical world) begins at the base of the skull. Seven vertebrae make up the cervical spine with eight pairs of cervical nerves. The individual cervical vertebrae are abbreviated C1, C2, C3, C4, C5, C6, and C7. The cervical nerves are also abbreviated; they are C1 through C8.
Vertebral Column Overview. The Vertebral column (spinal column) supports the head and encloses the spinal cord. The spinal column is comprised of 26 individual bones, these bones are referred to as vertebrae.The spinal column is divided into 5 different areas containing groups of vertebrae and are grouped as follows:7 cervical vertebrae in the neck. 12 thoracic vertebrae in the upper back corresponding to each pair of ribs. 5 lumbar vertebrae in the lower back.5 sacral vertebrae which are fused together to form 1 bone called the sacrum. 4 coccygeal vertebrae that are fused together to form the coccyx or tail-bone. The vertebrae are referred to by their name and number, counting down from the top of the spinal column as follows:he thoracic vertebrae are T1 - T12. The lumbar vertebrae are L1 - L5. The sacrum and coccyx do not have numbers and each is thought of as one bone. Spinal nerves exit the sacrum and coccyx at levels (Foramen) within the main structure of each vertebra.
