| Front | T1-T6 intercostal nerves |
|---|---|
| Back | Structure: arise from T1-T6 ventral rami and pass around the body deep to the ribs (in the intercostal neurovascular bundle) Components: somatomotor, somatosensory, symp/post Branches: 1. Motor branches 2. Lateral cutaneous nerves 3. Anterior cutaneous nerves 4. Somatosensory branches Function: 1. Somatosensory innervation to the costal parietal pleura and periphery of diaphragmatic parietal pleura 2. Cutaneous innervation of skin 3. Sensory and motor innervation of structures between parietal pleura and skin (ex: intercostal muscles) |
