What is the name of the openings in cervical vertebrae through which vertebral arteries pass?
The transverse foramen, through which the vertebral artery passes, is characteristic of the cervical vertebrae, except for the last, in which it is usually absent. FIGURE 7.9.
What structure in the cervical vertebrae does the vertebral artery go through?
The vertebral arteries arise from the subclavian arteries, one on each side of the body, then enter deep to the transverse process at the level of the 6th cervical vertebrae (C6), or occasionally (in 7.5% of cases) at the level of C7. They then proceed superiorly, in the transverse foramen of each cervical vertebra.
What are typical cervical vertebrae?
Typical Vertebrae: C3, C4, C5, and C6 Save. 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. Typical vertebrae have: Vertebral body.
What nerves are affected by C4 C5 C6 C7?
Classic Patterns of Cervical Radiculopathy
| Nerve root | Interspace | Pain distribution |
|---|---|---|
| C5 | C4–C5 | Neck, shoulder, lateral arm |
| C6 | C5–C6 | Neck, dorsal lateral (radial) arm, thumb |
| C7 | C6–C7 | Neck, dorsal lateral forearm, middle finger |
What is unique about cervical vertebrae?
Typical cervical vertebrae have several features distinct from those typical of thoracic or lumbar vertebrae. The most notable distinction is the presence of one foramen, in each transverse process. These transverse foramina encircle the vertebral arteries and veins.
What does C4 C5 C6 control?
The C4 dermatome covers parts of the neck, shoulders, and upper part of arms. The C6 dermatome covers the thumb side of the hand and forearm. 2. See All About the C5-C6 Spinal Motion Segment. C7 helps control the triceps (the large muscle on the back of the arm that straightens the elbow) and wrist extensor muscles.
How is C4 C5 herniated disc treated?
Treatment with rest, pain medication, spinal injections, and physical therapy is the first step to recovery. Most people improve in 6 weeks and return to normal activity. If symptoms continue, surgery may be recommended.
What is the main function of the cervical vertebrae?
The cervical spine functions to provide mobility and stability to the head while connecting it to the relatively immobile thoracic spine. The movement of nodding the head takes place predominantly through flexion and extension at the joint between the atlas and the occipital bone, the atlanto-occipital joint.
What are the main features of the cervical vertebrae?
The main anatomical characteristics of a typical cervical vertebra that separate it from other types of vertebrae are the small size, transverse foramina, saddle-shaped body, and bifid spinous process (Fig.
