Acetylcholinesterase is the enzyme that stops muscle stimulation when the motor neuron ceases firing. This enzyme enables acetyl and choline to release their binding sites.

Motor neuron firing refers to the process by which motor neurons generate action potentials, leading to the transmission of signals from the nervous system to muscles. When a motor neuron receives sufficient stimulation, it depolarizes and fires an action potential, causing the release of neurotransmitters at the neuromuscular junction. This triggers muscle contraction, enabling movement. The frequency and pattern of motor neuron firing can vary based on the type of movement being performed.
When a neuron in a muscle is fired, or triggered, it sends a message to the brain telling the muscle to contract.
The response of a motor unit to a single action potential of its motor neuron is called a muscle twitch. This involves the contraction of all the muscle fibers within the motor unit in response to the stimulation from the motor neuron.
The effector for somatic motor stimulation is the skeletal muscle. Somatic motor neurons innervate these muscles, leading to voluntary movements. The motor unit, consisting of a motor neuron and the muscle fibers it innervates, is responsible for muscle contraction in response to somatic motor stimulation.

A motor or efferent neuron.
When a postsynaptic neuron is stimulated by many terminals at the same time, it undergoes spatial summation. This simultaneous input from multiple presynaptic neurons can combine to reach the threshold for firing an action potential in the postsynaptic neuron. This process enables integration of signals from different sources to influence the overall excitability of the neuron.
A neuron reaches its trigger point when the combined inputs it receives from other neurons or sensory receptors exceed a certain threshold. Once this threshold is reached, the neuron generates an action potential, which propagates down its axon to communicate with other neurons or muscle cells.
