Detailed explanation-1: -Roots C5, C6, and C7 produce the long thoracic nerve, responsible for controlling the serratus anterior.
Detailed explanation-2: -Cervical nerve 6 controls the extensor muscles of your wrist and is involved in the control of your biceps. C6 provides sensation to the thumb side of your forearm and hand. Cervical nerve 7 controls your triceps and wrist extensor muscles. C7 provides sensation to the back of your arm into your middle finger.
