Those are efferent neurons (motor neurons).
- Somatic motor neurons: carry signals from the CNS to skeletal muscles (voluntary movement); use acetylcholine at the neuromuscular junction.
- Autonomic motor neurons: carry signals to glands, smooth muscle and cardiac muscle (involuntary). They branch into sympathetic and parasympathetic divisions, with different pathways and neurotransmitters (e.g., preganglionic ACh; postganglionic NE for most sympathetic targets, ACh for parasympathetic targets — with some exceptions).
