Ais a nerve cell whose cell body is located in the spinal cord and whose axon projects outside the spinal cord to directly or indirectly control our muscles. a) motor neuron b) muscle neuron c) synaptic neuron d) visceral neuron

The correct answer is A. motor neuron

A motor neuron is a neuron  whose cell body is located in the spinal cord and whose axon projects outside the spinal cord to directly or indirectly control our muscles.Many muscle fibres can be innervated by a single motor neuron.The activity of motor neurons is responsible for complex behaviors like locomotion.
