Similar to the rest of the spine (thoracic and lumbar), each of the vertebra of the cervical spine consists of a body, two pedicles, lamina, and multiple bony projections (called processes).
Some of these conditions are listed at the end of this article. There are many conditions of the spine that may affect the normal curvature of the cervical spine, resulting in pain and disability. The amount of lordosis an individual has varies, but typically is somewhere in the range of 20-40 degrees. In the cervical region, the spine normally curves backwards. The purpose of these curves is to grant some additionally flexibility and shock absorbing abilities to the spine. However, when viewing the spine from the side, there are distinct curves to each part of the spine. When looking from behind, in most individuals, the spine looks straight.
There are seven cervical vertebrae that allow for a great amount of motion in the neck. We will attempt to provide a simplified overview of this complex anatomy. Obliques Capitis Inferior– Assist with head / neck rotation Cervical Spine (Neck Bones): Bones of the Neck PictureĬervical spine anatomy is quite complex. Obliques Capitis Superior– Allows the neck to extend and flex to the side. Rectus Capitis Lateralis – Allows the neck to flex from side to side. Levator Scapulae – Responsible for movement of the scapula (shoulder blade) in an upward and downward motion. Scalene Muscles – Responsible for lifting the first and second ribs i.e. Rectus Capitis Lateralis– Helps the neck to bend to the side. Rectus Capitis Anterior– Responsible for flexion of the neck Longus Colli & Capitis – Responsible for flexion of the head and neck. Here is a list of the many muscles that exist in the neck. There are many muscles around the neck that help to support the cervical spine and allow you to move your head in different directions. Muscles of the Neck: Neck Anatomy Muscles Pictures Read on to learn more about the anatomy of the cervical spine. The cervical spine (neck), specifically, supports the weight of your head, allows you to look straight head, and protects the spinal cord and nerves. Secondarily, it protects the spinal cord (which is the extension of the brain) and all of the nerves that branch from the spinal cord. The purpose of the spine is to support the body so that we can stand upright.
