C7 nerve root pain is typically associated with weakness of which muscle group?

Explanation:
C7 radiculopathy most strongly affects elbow extension because the triceps muscle, which powerfully extends the elbow, is innervated by the nerve roots that include C7. When the C7 root is irritated or compressed, weakness appears in the triceps, leading to reduced ability to straighten the elbow against resistance. The triceps reflex, a classic C7 sign, is often diminished as well. Other options align with different root levels—deltoid with C5-6, biceps with C5-6, and wrist extensors more associated with C6-7—so the most characteristic weakness for a C7 issue is in the triceps.
