The Thoracic Spine
The Thoracic Spine, commonly
referred to as your middle back, consists of 12 vertebrae, (T1 - T12). This is
the longest portion of your back.
Some of the surface areas these nerves go to include parts of the arms from the elbows down, the hands, and fingers. Also the muscles of the middle back, the chest muscles, and muscles of the rib cage are supplied by nerves that exit out from this area of the spine.
The internal organs supplied by
nerves from the thoracic spine include much of the body parts supplied by the
sympathetic nervous system. This portion of the nervous system innervates many
of the organs in the chest and abdomen including, the heart, lungs, bronchial
tubes, gallbladder, liver, stomach, pancreas, spleen, adrenal glands, kidneys,
and small intestines.
