What does C6/C7 vertebrae control?
The C6-C7 Nerve Root This nerve root controls both muscle and skin in the arm via its sensory and motor roots. Some basic actions like stretching the fingers, contracting the triceps, and moving the elbow and wrists are controlled by the C7 motor roots.
What spinal nerve is between C6 and C7?
The C7 spinal nerve exits through the intervertebral foramen between the C6 and C7 vertebrae. This nerve has a sensory root and a motor root.
Can C5-C6/C7 cause back pain?
The C5-C6 disc is one of the most common to herniate. C6-C7 (C7 nerve root): Pain, tingling, and/or numbness may radiate into the hand and middle finger. Weakness may also be felt in the triceps (muscles in the back of the upper arm), finger extensors, and other muscles.
Where is C5-C6 and C7 in your neck?
The C5-C6 spinal motion segment (located in the lower cervical spine just above the C7 vertebra) provides flexibility and support to much of the neck and the head above.
Which cervical nerves affect vision?
When C2 – C3 instability is present, it is a likely structural cause of vision problems. Another way upper cervical instability affects vision is through the optic nerve.
How do you sleep with a herniated c6 c7?
Recommended Sleeping Positions for a Herniated Disc
- Side Sleepers – Choose a slightly thicker pillow to keep your spine straight as you lay on your side.
- Back Sleepers – Choose a thinner pillow to avoid tilting your head at an upwards angle.
- Side Sleepers – Place a pillow of medium thickness between your knees.
What is the C6 vertebra?
The C6 vertebra is the sixth cervical vertebra of the spine. It is found in the base of the neck between the C5 and the last cervical vertebra, C7. The C6 vertebra plays an important role in supporting and protecting the structures of the head and neck as well as anchoring the muscles that move and support the neck.
What is unique about C7 vertebra?
Unique Vertebra: C7. The seventh cervical vertebra, also called the vertebra prominens, is considered a unique vertebra and usually has the most prominent spinous process. When feeling the back of the neck, the C7 vertebra’s bony spinous process will stick out more than the other cervical vertebrae.
Is C8 a vertebrae?
The vertebra prominens is the last bone in the cervical spinal column group. Since it is not a vertebrae, C8 is also labeled as the cervical spinal nerve 8. The C6 vertebra is found in the inferior end of the neck, just above the thorax.
What happens if the C7 vertebra forms a rib?
In rare cases when the C7 vertebra forms a cervical rib, compression of surrounding blood vessels and/or nerves may occur, resulting in thoracic outlet syndrome. 2,7 A vertebral and/or disc injury at the C6-C7 motion segment may cause immediate or delayed symptoms.
