- Brain
- PERIPHERAL
- Somatic
- Efferent/Motor: primary motor cortex glutamatergic UMNs > corticospinal tract > anterior horn cholinergic alpha motor neurons (LMNs) > ventral roots > peripheral nerves > nAChRs on skeletal muscles
- Afferent/Sensory: peripheral sensory receptors > peripheral nerves > dorsal roots > DCML/spinothalamic
- Autonomic
- Sympathetic
- Efferent: 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
