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.
Movement about the wrist is due to muscles in the forearm, with movement of the fingers due to muscles of both the forearm and hands. Summarize the movements of the muscles of the wrist and hand. Movements of the wrist include abduction and adduction and extension and flexion.
