- Midbrain

- Spinal Cord
- Cervical
- Thoracic
- Lumbar
- Sacral
- Brain
- PERIPHERAL
- Somatic
- Motor: primary motor cortex glutamatergic UMNs > corticospinal tract > anterior horn cholinergic alpha motor neurons (LMNs) > ventral roots > peripheral nerves > nAChRs on skeletal muscles
- Sensory: peripheral sensory receptors > peripheral nerves > dorsal roots > DCML/spinothalamic
- Autonomic
- Sympathetic: lateral horn cholinergic preganglionic neurons > ventral roots > white ramus communicans > paravertebral sympathetic chain or prevertebral ganglia > postganglionic noradrenergic neurons > gray ramus communicans > peripheral nerves > adrenergic receptors (α1/α2，β1/β2) on target organs
- Parasympathetic: craniosacral outflow from CN III/VII/IX/X and S2-S4 > peripheral ganglia near target organs > target organs
- Enteric
- Somatic
