When a neuron responds to a particular neurotransmitter by opening gated ion channels the neurotransmitter is serving as which part of the signal pathway?
The neurotransmitter functions as the ligand that binds to the receptor on the neuron's membrane, causing a conformational change that opens the ion channels. This allows ions to flow into or out of the neuron, resulting in a change in its membrane potential and ultimately transmitting the signal.
How is the signal between neurons stopped?
The signal between neurons is primarily stopped through the process of neurotransmitter reuptake and enzymatic degradation. After neurotransmitters are released into the synaptic cleft and bind to receptors on the postsynaptic neuron, they are either reabsorbed into the presynaptic neuron by transporters or broken down by enzymes. This cessation of neurotransmitter action prevents continuous stimulation of the postsynaptic neuron, effectively terminating the signal. Additionally, some neurotransmitters may diffuse away from the synapse, further contributing to signal termination.
What is the entire series of events through a three-neuron loop?
In a three-neuron loop, the first neuron sends a signal to the second neuron via a synapse. The second neuron processes the signal and sends it to the third neuron through another synapse. Finally, the third neuron integrates the signal and produces a response or transmits it further in the neural network.
When there is e leftover neurotransmitter in the synaptic gap what occurs?
If there is leftover neurotransmitter in the synaptic gap, it can be taken back up into the presynaptic neuron through a process called reuptake or broken down by enzymes to clear the signal between neurons. This recycling process helps ensure that the signal is only transmitted when and where it is needed to prevent overstimulation of the postsynaptic neuron.
What Chemical messengers that transport nerve impulses from one nerve cell to another are called?
Chemical messengers that transmit nerve impulses from one nerve cell to another are called neurotransmitters. These molecules are released from the axon terminals of one neuron and bind to receptors on the dendrites of another neuron to propagate the signal. Common neurotransmitters include dopamine, serotonin, and acetylcholine.
When one neuron wants to stimulate another it will?
A neuron releases a chemical called a neurotransmitter that will signal other neurons.
A chemical released from one neuron to another is?
A neurotransmitter.
What is the relationship between a synapse and neurotransmitter?
Chemical synapses are specialized junctions through which neurons signal to each other and to non-neuronal cells such as those in muscles or glands. At a chemical synapse, one neuron releases a neurotransmitter into a small space (the synapse) that is adjacent to another neuron.
When a neuron responds to a particular neurotransmitter by opening gated ion channels the neurotransmitter is serving as which part of the signal pathway?
The neurotransmitter functions as the ligand that binds to the receptor on the neuron's membrane, causing a conformational change that opens the ion channels. This allows ions to flow into or out of the neuron, resulting in a change in its membrane potential and ultimately transmitting the signal.
What process describes how a signal travels from one end of a neuron to the other a. hormonal requlation B. muscle coordination C. membrane excitability d. neurotransmitter release?
The process that describes how a signal travels from one end of a neuron to the other is called neurotransmitter release. Neurons are very important.
What kind of potential is it when a neuron fires?
When a signal is sent out from the nervous system it is caused a release of a neurotransmitter that releases an action potential.
The part of the neuron that facilitates synaptic transmission of a signal to another neuron is?
Soma
What is the part of neuron that facilitates synoptic transmission of signal to another neuron?
synapse

What is presynaptic inhibition and how does it regulate neurotransmitter release in the nervous system?
Presynaptic inhibition is a process in which the release of neurotransmitters from a neuron is reduced by another neuron. This regulation occurs when the inhibitory neuron releases a neurotransmitter that decreases the excitability of the presynaptic neuron, leading to a decrease in neurotransmitter release. This mechanism helps to fine-tune communication between neurons and maintain balance in the nervous system.
What is the function of the dendrites in the neuron?
The dendrites receive the data or signal from another neuron for the soma.
What is the entire series of events through a three-neuron loop?
In a three-neuron loop, the first neuron sends a signal to the second neuron via a synapse. The second neuron processes the signal and sends it to the third neuron through another synapse. Finally, the third neuron integrates the signal and produces a response or transmits it further in the neural network.
