What stops muscle stimulation when the motor neuron ceases firing?

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.


What is motor neuron firing?

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.


A brief change in electrical voltage in the neuron in response to stimulation is called what?

an action potential


What is the amount of stimulation required to intiate a nerve impulse called?

How is depolarization in a hair cell different from depolarization in a typical neuron?

Depolarization in a hair cell is triggered by mechanical stimulation, such as sound waves or movement, while depolarization in a typical neuron is triggered by chemical signals.


What are the 5 steps to a reflex arc?

Would increasing frequency of stimulation to trigger zone change number of action potentials?

Yes, increasing the frequency of stimulation can increase the number of action potentials generated in the neuron. This is known as frequency-dependent facilitation, where rapid succession of stimuli can enhance the excitability of the neuron and lead to more action potentials being fired.


In a neuron impulses move?

In a neuron, impulses move through electrical signals known as action potentials. These action potentials are generated when a neuron receives enough stimulation to reach a threshold, causing a rapid change in membrane potential. The action potential then travels down the length of the neuron's axon until it reaches the next neuron or target cell.
