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.
Neck anatomy is a well-engineered structure of bones, nerves, muscles, ligaments and tendons. The cervical spine (neck) is delicateâhousing the spinal cord that sends messages from the brain to control all aspects of the bodyâwhile also remarkably strong and flexible, allowing movement in all directions. The neck is connected to the upper back through a series of seven vertebral segments. Watch: Cervical Spine Anatomy Video. The neck begins at the base of the skull and through a series of seven vertebral segments connects to the thoracic spine (the upper back).
