'''Motoneurons''' (also called [['''motor neurons''') are [[neuron]]s) arewhich interface with [[neuronmotor unit]]s; they cause [[skeletal muscle]] to contract.

More precisely, they are neurons originating in the [[spinal cord]] which efferently innervate [[muscle]]s. Upon excitement, nearly all motoneurons release the [[neurotransmitter]] [[acetylcholine]] at [[synapse]]s called [[neuromuscular junction]]s in order to initiate muscle contraction.
