Conscious or voluntary regulation
Fibres do not synapse after they leave the CNS (single neuron from CNS to effector organ) Innervates skeletal muscle fibres, always stimulatory |
Functions without conscious awareness (involuntary) Fibres synapse once at a ganglion after they leave the CNS (two neuron chain motor control Innervates smooth muscle, cardiac muscle and glands either stimulates or inhibits |
