What does C2 and C3 control?

What does C2 and C3 control?

C1, C2, and C3 (the first three cervical nerves) help control the head and neck, including movements forward, backward, and to the sides. The C2 dermatome handles sensation for the upper part of the head, and the C3 dermatome covers the side of the face and back of the head.

What is the name of cervical 2?

Overview. The cervical spine is made up of 7 vertebrae. The first 2, C1 and C2, are highly specialized and are given unique names: atlas and axis, respectively. C3-C7 are more classic vertebrae, having a body, pedicles, laminae, spinous processes, and facet joints.

What are the cervical levels?

Typical Vertebrae: C3, C4, C5, and C6 C3, C4, C5, and C6 cervical vertebrae. Cervical vertebrae C3 through C6 are known as typical vertebrae because they share the same basic characteristics with most of the vertebrae throughout the rest of the spine.

Why are C1 and C2 special?

Since the C1 and C2 vertebrae are the most high up, they are very important for supporting the skull, allowing for the head to rotate, and protecting the spinal cord. If they become damaged, then the nerves carrying messages from the brain to the rest of the body are also affected.

What nerves are affected by C2?

The C2 nerves affect sensation at the top and back of the scalp, ear lobes, and front of the neck. They also affect the muscles used for neck flexion (nodding).

Where is C3 and C4?

The C3, C4, and C5 vertebrae form the midsection of the cervical spine, near the base of the neck. A cervical vertebrae injury is the most severe of all spinal cord injuries because the higher up in the spine an injury occurs, the more damage that is caused to the central nervous system.

Where is C3 C7?

C3-C7 Vertebrae, Cervical Discs, Supporting Structures At the back of the vertebral body are bony arches that project outward to form the facet joints and spinous processes.

What nerves are affected by C3 C4?

Branches of the C3, C4, and C5 spinal nerves form the phrenic nerve that innervates the diaphragm, enabling breathing. Within the spinal canal of each of these motion segments, the spinal cord is protected by the vertebral bodies in front and vertebral arches at the back.

What nerves are affected by C3 C4 C5 C6 C7?

C5, as mentioned earlier, along with C3 and C4, contributes to the phrenic nerve that innervates the diaphragm. Roots C5, C6, and C7 produce the long thoracic nerve, responsible for controlling the serratus anterior.
