Which statement is FALSE about the motor neuron to muscle activation sequence? Group of answer choices Glutamate binds to glutamate receptors on the cell body of the lower motor neuron. Acetylcholinesterase clears the neuromuscular junction of acetylcholine for normal muscle function. The activation sequence can only occur in one direction. Once initiated, an action potential is propagated the entire distance from the upper motor neuron to the muscle cell. Acetylcholine binding to nicotinic acetylcholine receptors allows sodium to come into the skeletal muscle cell and initiate an action potential.

Option D - Once initiated, an action potential is propagated the entire distance from the upper motor neuron to the muscle cell.

Explanation:

What happens when action potential is initiated is that it travels to the nerve ending where it propels the release of neurotransmitter.

Only action potential travels down to the next neuron, in a case where the released neurotransmitter is excitatory, otherwise, the action potential won't travel beyond if the neurotransmitter is inhibitory.
