Autonomic neurons are also carried by the spinal nerves and carry signals to autonomic ganglia and further on to the organs of the trunk.
The intercostal nerves supply the entire thoracic wall. These nerves are the anterior rami of the first 11 thoracic spinal nerves. Branches of intercostal nerves: 1. Rami communicantes – connects intercostal nerve to ganglion of sympathetic trunk 2.
