A neuron reaches its trigger point when?
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.
What messages provide chemical information that prevents or decreases the likelihood that the receiving neuron will fire?
Inhibitory messages provide chemical information that prevents or decreases the likelihood that the receiving neuron will fire. These messages typically involve neurotransmitters such as GABA or glycine, which hyperpolarize the neuron's membrane potential, making it less likely to reach the threshold for firing an action potential.
Is a 350 Chevy small block and a 396 big block the same firing order?
No, they do not have the same firing order. The 350 Chevy small block typically uses a firing order of 1-8-4-3-6-5-7-2, while the 396 big block uses a firing order of 1-8-4-3-6-5-7-2.
What is the firing order for proton wira?
The Proton Wira firing order is 1-2-3-4 for the four-cylinder VDO engine. This fuel injected engine came into use in 1991 and is slightly different than previous models, some of which included carburetors.
What condition is neuron in when the outside of the neuron has a net positive charge and the inside has net negative charge?
This is called the resting potential (inactive state) of the neuron. However, when a neurotransmitter binds to receptors, electrical stimulus is applied, etc. to induce an opening of ion channels in the membrane of the neuron, positive ions rush into the neuron from the outside to the inside, and result in a sharp increase of the positive charge density (due to more positive ions) inside the neuron. Beyond a certain threshold, this can induce the creation of an action potential, causing the neuron to fire. After the action potential is created, and the neuron fires, there is a short refractory period where the neuron cannot be fired again due to stimuli, when positive ions are pumped back out of the neuron, negative ions are brought into the neuron, and then the ion channels close, leaving the neuron in a polarized state, and returning it to a resting potential.
What is mean by the all or none response of a neuron?
The simplest sense, the all-or-none principle of neuronal firing means that a neuron will either fire or it won't, there is no "half" firing. When a neuron receives excitatory input.
When a neuron fires is there such thing as partial firing?
yes
Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter
Can the firing of one neuron produce temporal summation?
True
What do you call the state of a neuron when it is firing a neural impulse?
Resting potential.
The state of the neuron when not firing a neural impulse is known as?
Resting potential
What do you call the state of a neuron when it is not firing a neural impulse?
The state of a neuron when it is not firing a neural impulse is called the resting potential. This is when the neuron is negatively charged inside compared to outside, waiting for a stimulus to change its electrical charge and initiate an action potential.
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 the firing frequency equation?
The firing frequency of a neuron can be estimated by dividing the total number of action potentials generated by the neuron within a given time period by that time period. This can be mathematically expressed as: Firing Frequency (Hz) = Number of Action Potentials / Time Period.
What does long term potentiation theory refer to?
an increase in a neuron's firing potential.
What was the firing order of Nissan diesel RE10?
firing order
Transmit neural messages from neuron to neuron?
Neurons send messages by way of chemical signalers called neurotransmitters. An activated neuron releases neurotransmitters and their collective action can stimulate another neuron. These individual firing sequences are called action potentials.
