| Front | Sympathetic post-ganglionic neurons |
|---|---|
| Back | (Symp/post) Structure: the second neuron in the two-neuron sympathetic autonomic system, has cell bodies located in the sympathetic truck (paravertebral ganglia) Pathway to viscera: 1. Sympathetic trunk 2. Splanchnic nerves 3. Visceral plexuses 4. Synapses on wall of organ Pathway to body wall: 1. Paravertebral ganglia of sympathetic trunk 2. Grey communicating rami 3. Spinal nerve 4. Peripheral nerve branches via dorsal or ventral rami 5. Body wall Function: provides "fight or flight" signals to target structures a) blood vessels - vasoconstriction b) heart - increases rate c) coronary arteries - vasodilation d) bronchi - dilation e) sweat glands, arrector pili muscles of body wall |
