The neck, or cervical region, referred to as C1 to C8, control signals
to the neck,  arms, hands, and to respiration. These injuries usually
result in quadriplegia. Injuries above the C-4 level may require a
ventilator for the person to breathe

The thoracic or upper back region, T1 to T12, control signals to the
torso and some parts of the arms. Individuals with injuries at T1 may
straighten their arms but still may have dexterity problems with the
hand and fingers. In injuries from level T1 to T-8 there can be
control of the hands, but poor trunk control
