Thoracic and Lumbar Ventral Rami Flashcards
The grey ramus communicans joins to the ventral rami of the thoracic spinal nerve (proximal/distal) to the exit of the white ramus.
Proximal.
Each of the thoracic ventral rami connects to the adjacent sympathetic ganglion thru the (grey, white, or both) rami communicans.
