What does all or non response mean to human anatomy?
All-or-none response means that things have to reach a certain threshold, a certain level before they happen. If it reaches that threshold, it becomes a cascading response that increases in size. If it fails to reach the threshold, well, nothing happens.
What opens first in response to threshold stimulus?
The activation gates of voltage-gated Na+ channels open, and Na+ diffuses into the cytoplasm.
Why are action potentials said to be all or none?
All or nothing response of an action potential (AP), refers simply to the fact that an AP will either occur, or not. There is no gradient, no half APs or double APs. The only option is AP, or no AP. Like in computer binary, the response is either 1 (an AP) or 0 (no AP). All the factors trying to induce (or inhibit) an action potential (i.e other action potentials, EPSPs and IPSPs) add up (summate) at the axon hillock, (aka the trigger zone). Here, if the stimulation is big enough an action potential will occur. If the stimulation is not big enough, no action potential occurs.
What is the nerve that send signals to the brain?
They are neurons!=The neurons take all the information to the brain so you can do what you can do with them.Without them,you wouldn't know what "know" means at all even though I just said it!=
Write to basic properties of Nuron?
Excitability / irritability: This means they can be stimulated to produce an impulse (action potential) – a tiny electrical current. Conductivity: This means neurons are also able to transfer an impulse along the full length of their axons and then on to other neurons, muscles or glands.

What specific effects oes cafffine have on neurons?
The effect that caffeine has on neurons is to make them more sensitive to the effects of neurotransmitters. Caffeine lowers the threshold and makes the neurons more sensitive. This means it takes less of the neurotransmitter to affect another neuron.
What is high threshold means?
High threshold refers to the level of stimulus or intensity required to elicit a response from a muscle or neuron. In the context of exercise, individuals with a high threshold may require more challenging or intense exercises to effectively engage their muscles and promote strength gains.
Where do interneurons connect sensory neurons and motor neurons?
Interneurons means synapses probably. They connect two neurons.
What opens first in response to threshold stimulus?
The activation gates of voltage-gated Na+ channels open, and Na+ diffuses into the cytoplasm.
What does notice of litigation threshold means?
Notice of litigation threshold means that someone has legal proceedings about to be brought upon them and that the notice is to make them aware of those proceedings beforehand.
What is olfactory neurons?
They process and relay sensory input from your nose.
What is a high threshold?
Having a high pain threshold means you can take more pain than most people without it becoming unbearable
What is a word that means without respect?
A word that means without respect is disrespect.
How do non functional sodium channels affect the signaling capabilities of neurons?
When sodium enters the neuron, it depolarizes it. This means that the neuron becomes more positive. This can lead to the neuron reaching threshold and then initiate an action potential. When the sodium channels are NOT functional, the sodium can not enter and depolarize it. Therefore the threshold can not be met and action potential will not occur. If the sodium channels are inactive in an nociceptive neruon (carries information about pain), then the it will prevent you from feeling pain.
What is meant by the threshold point of a diode?
it means the entrance point of a diode
What does general respect mean in ethics?
General respect means respect for everyone.
