What nerves are affected by C2 3?
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 nerve is between C2 and C3?
transverse cervical nerve
The transverse cervical nerve, of C2 and C3, projects posteriorly and wraps around anteriorly to supply the skin of the anterior cervical region. The supraclavicular nerve, of C3 and C4, descends from the posterior sternocleidomastoid and provides sensory information from the skin over the clavicle and shoulder.
What does C2 C3 mean?
C3 Spinal Vertebra Defined The C2 – C3 junction of the spinal column is important, as this is where flexion and extension occur (flexion is the movement of the chin toward the chest and extension is the backward movement of the head).
What does the C2 control?
The C1 vertebrae is named atlas and the C2 vertebrae is named axis. As well as protecting the spinal cord, these vertebrae are primarily responsible for facilitating and controlling the large range of movement that your neck has, and supporting the considerable weight of your skull at the tip of your spine.
What muscles are innervated by C2 C3?
Lesser occipital nerve – innervates the skin and the scalp posterosuperior to the auricle (C2) Great auricular nerve – innervates skin near concha auricle (outer ear) and external acoustic meatus (ear canal) (C2&C3) Transverse cervical nerve – innervates anterior region of neck (C2 and C3)
What are the symptoms of a pinched nerve at c3?
Symptoms of pinched nerve in the neck include:
- A sharp pain in the arm.
- Pain in the shoulder.
- A feeling of numbness or pins and needles in the arm.
- Weakness of the arm.
- Worsening pain when you move your neck or turn your head.
What does C2 supply?
It originates from the spinal column from above the cervical vertebra 2 (C2). it innervates the rectus capitis anterior and rectus capitis lateralis muscles, and provides sensory nerves to the trapezius.
