Neck pain often arises from tight neck muscles that pull the neck vertebrae slightly out of alignment, called subluxation, which then impinge on sensory nerves entering the spine between these vertebrae. These sensory nerves relay that information back to the brain setting off the alarm in the form of pain.
Wrist Bending. Forward bending of your wrist is called flexion. This motion is needed for daily activities such as styling your hair, writing, getting dressed, using a screwdriver and lifting heavy objects. Normal wrist flexion is approximately 70 to 90 degrees.
The movement and power of your hand and wrist are controlled by muscles and tendons: 1  The flexor group, on the inside or front of the arm, control bending of your fingers and wrist â these pass over the front of your wrist and are held in place by a strong fibrous band called the flexor retinaculum, or carpal tunnel ligament.
