What nerves are affected by c4 C5 C6 and C7?

From the lateral cord, C5, C6, and C7 supply the pectoralis major and minor muscles, via the lateral and medial pectoral nerves, as well as the coracobrachialis, brachialis and biceps brachii, via the musculocutaneous nerve. The musculocutaneous nerve provides sensation to the skin of the lateral forearm.

What nerve root is most commonly affected in a cervical radiculopathy?

What does C4-C5 C6 control?

The C2-C5 motion segments contribute the most to the mid-range of motion during the neck’s forward and/or backward movements. C4-C5 is typically more mobile compared to other motion segments between C2-C5. The lower cervical spine (C5-C7) is typically injured more often compared to C2-C5.
