: Provide sensory information to the chest wall and motor control to the intercostal muscles used in breathing.
| Feature | Details | |---------|---------| | | 12 (T1 – T12) | | Main function | Motor: trunk muscles (breathing & posture) Sensory: trunk & upper abdomen | | Special nerves | T1 → arm T7-T11 → abdominal wall T12 → subcostal nerve | | Clinical landmark | T4 nipple / T10 umbilicus | | Common pathology | Shingles, intercostal neuralgia |
There are , designated T1 through T12 . They emerge from the spinal cord through the intervertebral foramina (small openings between the vertebrae).
: The serratus anterior pulls the scapula (shoulder blade) forward against the rib cage, enabling the arm to be raised forward and upward (abduction and elevation). It also assists in deep respiration by lifting the ribs. Thoracic Spinal Nerves (T1–T12)

The are the 12 pairs of spinal nerves emerging from the thoracic region of the spinal cord (T1 to T12). They control chest and abdominal wall muscles, provide sensation to the torso and upper abdomen, and include the unique T1 nerve (which helps form the brachial plexus for the arm) and T12 (subcostal nerve).
