What nerves are affected by C4-C5?

What nerves are affected by C4-C5?

Roots. The C4 and C5 roots give rise to the dorsal scapular nerve that supplies the rhomboids and levator scapulae.

  • Trunks. From the upper trunk C5 and C6 give rise to the nerve to the subclavius, and the suprascapular nerve, that supply the subclavius muscle, and the supra- and infraspinatus muscles, respectively.
  • Cords.
  • What does the C4 and C5 nerves control?

    1. The C4 dermatome covers parts of the neck, shoulders, and upper part of arms. 2. C5 helps control the deltoids (which form the rounded contours of the shoulders) and the biceps (which allow bending of the elbow and rotation of the forearm).

    What does C4-C5 vertebrae control?

    A bulging disc or herniated disc in the c4-c5 level of the cervical spine can affect the nerves that control the arms, hands, shoulders, neck, head, chest, eyes, and many other parts of the body.

    Can C4 C5 cause headaches?

    It has been reported that pain from the C2-3 and C3-4 cervical facet joints can radiate to the occipital area, frontotemporal and even periorbital regions. Even pathology in C5 or C6 nerve roots have been reported to cause headache.

    What nerve exits between C4 and C5?

    Unlike the lumbar spine, the cervical spine has cervical nerve roots that exit above the level of the corresponding pedicle. For instance, the C5 nerve root exits at the C4-C5 disk space, and a C4-C5 disk herniation typically leads to C5 radiculopathy. There are seven cervical vertebrae and eight cervical nerve roots.
