What else can I help you with?
What is the regeneration of action potential called?
The regeneration of action potential is called "propagation." It involves the transmission of the action potential along the length of the neuron's axon.
What stimulus below this intensity will result in no response in a neuron?
Any stimulus below the neuron's threshold potential will not result in a response, as it is not strong enough to generate an action potential. Neurons require a minimum level of stimulus intensity to reach the threshold potential and fire an action potential.
Where do neurotransmitters that bind the postsynaptic membrane generate?
Neurotransmitters that bind to the postsynaptic membrane generate a response by either depolarizing or hyperpolarizing the postsynaptic neuron. This response can lead to the generation of an action potential if the threshold is reached, propagating the signal further along the neuron.
What is the response if you increase the stimulus intensity past the threshold level for a neuron?
Increasing the stimulus intensity past the threshold level for a neuron will not further increase the action potential generated. Once the threshold is reached, the neuron will fire an action potential at its maximum intensity.
What is the interval called during which a neuron is dormant after an action potential has been completed?
Resting potential
A brief change in electrical voltage in the neuron in response to stimulation is called what?
an action potential
Response of a motor unit to a single action potential of it motor neuron is called?
muscle twitch
An environmental stimulus acting on the body initially produces an electrical response called aan in the receptor neuron?
The electrical response in the receptor neuron is called an action potential. This action potential is generated when environmental stimuli cause depolarization of the neuron's membrane, allowing positive ions to enter and create a temporary change in electrical charge. This signal is then propagated along the neuron for further processing in the nervous system.
What structure in the neuron accelerates the transmission of the action potential?
The structure in the neuron that accelerates the transmission of the action potential is called the myelin sheath.
What is the regeneration of action potential called?

What is the interval called during which a neuron is dormant after an action potential has been completed?
Resting potential
Is the action potential an all-or-nothing response in neurons?
Yes, the action potential is an all-or-nothing response in neurons, meaning that once a certain threshold is reached, the neuron will fire at full strength regardless of the strength of the stimulus.
What happens at the level of the neuron starting with stimulus and ending with a response?
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.
When you touch something hot a neuron in your fingers senses the temperature which best decscribes the first reaction the neuron has?
Ions flow into the neuron. An action potential forms moves along the neuron. A response occurs, here, an aversion response... your body pulls your hand and finger away.
