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 range of motion is measured with the elbow bent to 90 degrees and from neutral -- with the elbow against the body and the forearm in front of the body -- to the widest point that the forearm can move toward the body.
