Motorneurons
Usually very large & multipolar
Many located in CNS and project axons outside to directly or indirectly control muscle actions
Long axons that travel to an effector organ- a muscle or a gland
They are the final common pathway for getting things done
Classified according to their targets e.g. somatic, visceral or autonomic
Different Types of Motoneurons
- Somatic motoneurons which supply voluntary ('striated') muscle
- Visceral (autonomic) motoneurons which supply involuntary ('smooth') muscle, cardiac muscle and glands
- Special neurosecretory motoneurons in the hypothalamus
