The C1 vertebra, known as the atlas, is the superior-most vertebra in the spinal column. It plays vital roles in the support of the skull, spinal cord, and vertebral arteries and provides attachment points for several muscles of the neck.
What is the function of C1 and C2?
The C1 and C2 vertebrae function together to give your head flexibility. With the atlas and axis relationship, you are able to swivel and rotate your head, as well as support your head. These two vertebrae are more responsible for the head’s rotational range of motion than from any other joint.
What does C1 control?
C1, C2, and C3 (the first three cervical nerves) help control the head and neck, including movements forward, backward, and to the sides.
What is the name and function of the C1 vertebrae?
The atlas (C1) is the topmost vertebra, and along with the axis forms the joint connecting the skull and spine.
What is the C1?
The C1 atlas is the uppermost cervical vertebra of the spine. It supports the head and — along with the C2 axis, the cervical vertebra just below it — allows the head to nod and rotate from side to side.
What nerve is C1?
The cervical spinal nerve 1 (C1) is a spinal nerve of the cervical segment. C1 carries predominantly motor fibres, but also a small meningeal branch that supplies sensation to parts of the dura around the foramen magnum (via dorsal rami).

What structure does C1 articulate with?
The atlas (plural: atlases) is the first cervical vertebra, commonly called C1. It is an atypical cervical vertebra with unique features. It articulates with the dens of the axis and the occiput, respectively allowing rotation of the head, and flexion, extension and lateral flexion of the head.
Why is C1 atlas?
In anatomy, the atlas (C1) is the most superior (first) cervical vertebra of the spine and is located in the neck.

What is C2 known as?
C2 (cervical vertebra): C2 is the symbol for the second cervical vertebra, which is also called the axis. It is so-named because the uppermost cervical vertebra (called the atlas) rotates about the odontoid process of the second cervical vertebra.
Does C1 have a ventral root?
In the rat, cat, mouse and monkey, ventral roots of C1-C8 and L3-S1 segments, which are outside the autonomic (thoracolumbar) outflow, contain C fibers (Clifton et al., 1976, Coggeshall and Ito, 1977, Coggeshall et al., 1977, Biscoe et al., 1982, Chung and Kang, 1987, Karlsson et al., 1991).
What causes C1 misalignment?
A misalignment at C0-C1-C2 can also come from sitting at a desk with poor posture, birth trauma, or falling out of a tree when you are a child. However, the most common way we see large trauma produced is from a concussion from either sports or work related injuries, or a car accident.
Does C1 have dorsal root ganglion?
C1 and C2 spinal nerves were identified in 100% of the specimens examined. In 46.6% of specimens, C1 dorsal rootlets were identified and of these, 28.5% had an associated dorsal root ganglion. In 50% of specimens, the spinal accessory nerve joined with dorsal rootlets of C1.
How do you stretch C1 and C2?

What happens if you break your C2 vertebrae?
Symptoms of a minor C2 fracture can include problems moving the neck, pain, swelling, tenderness, trouble swallowing, loss of feeling or a tingling sensation in the arms and legs,numbness or pain at the base of the head, double vision, or loss of consciousness.
Can neck problems affect your legs?
Cervical spinal stenosis can potentially cause serious problems with the nervous system, including problems with bowel or bladder control (incontinence) and permanent loss of strength and feeling in the arms, hands, legs, and chest.
Where is C2 in your neck?
Bones of the spine are called vertebrae. The bone involved in hangman’s fracture is the second vertebra, toward the top of the neck, close to the skull. It is designated as C2: “C” for its location in the cervical spine (spine in the neck), and “2” for its position as the second bone in that spinal segment.
Can a broken neck cause brain damage?
Brain damage was more frequently associated with upper cervical injury. Those patients with upper cervical injury are at greater risk of suffering from skull base fractures and severe intracranial hematomas than those with mid to lower cervical injury.
How do you adjust C1 and C2 at home?
Adjustment to C1 and C2 for NECK PAIN – YouTube
Can neck cause eye problems?
Up to 70% of people will experience neck pain that interferes with their daily activities. Tension in the neck and shoulders can lead to eye strain, as tense muscles can press on eye nerves at the back of your neck.
Can C1 be adjusted?
Through a C1 adjustment, patients achieve improved circulation and reduced pain. The improved blood flow allows oxygen and nutrients to reach the different parts of the body faster, improving overall health.
Does C1 have a sensory root?
The presence of a sensory component in the first cervical (C1) spinal nerve in adult humans is not well understood. … These recent studies have found that dorsal root component of C1 is often absent, and the dorsal root ganglia cannot always be identified when a dorsal root is present (Tubbs et al., 2007, 2009).

What is a C1 lateral mass fracture?
A C1 (atlas) vertebral fracture that usually occurs after an axial load injury during a diving accident. When there are both anterior and posterior arch fractures this is called a “burst” fracture (also known as a Jefferson’s fracture) and occurs when the occipital condyles are forced into the lateral masses of C1.
Can nerves in your neck cause headaches?
One of the more common medical causes of headaches are pinched nerves in the neck. Pinched nerves in the neck cause headaches by compressing the nerve which generates a feeling of pain along the nerve’s pathway. Cervical Radiculopathy is a medical condition where a nerve in the upper spine becomes compressed.
