Conversation so far:
what is the job of a motor neuron
A single motor neuron may innervate many muscle fibres and a muscle fibre can undergo many action potentials in the time taken for a single muscle twitch.
where is the motor neuron located
A motor neuron is a neuron whose cell body is located in the motor cortex, brainstem or the spinal cord.
what types of motor neurons are there
There are two types of motor neuron – upper motor neurons and lower motor neurons.
what is an upper motor neuron
Upper motor neurons are found in the cerebral cortex and brainstem and carry information down to activate interneurons and lower motor neurons, which in turn directly signal muscles.

Question: what is a lower
Self-contained rewrite: what is a lower motor neuron
