When the binding of a neurotransmitter to a dendrite will result in?

∙ 10y ago
The binding of a neurotransmitter to a dendrite will cause one these three things to happen:
- excitement (stimulation)
- inhibition (stop activity)
- modulation (change activity by slowing it or increasing it)
It all depends on the neurotransmitter. Neurotransmitter are means by which neurons communicate with one another. There are more than 30 compounds known to be neurotransmitters, and dozens of others are thought to be so.

What is hyperpolarization of a dendrite by a neurotransmitter called?
According to Biologists, the hyper polarization of a dendrite by a neurotransmitter is known as an inhibitory postsynaptic potential (IPSP).
______ have receptors for the neurotransmitter by which impulse transmits and forward in the next nerve?
Synaptic of dendrite
What part of neuron releases neurotransmitter my choices are axon axon terminal dendrite myelin sheath or cell body?
The neurotransmitter is released from the axon terminal.
Binding of neurotransmitter to the receptors on the motor endplate open?
Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate. Further down the line, this would cause muscle contraction through the release of Ca2+ from the SR.
How does the nervous system change?
neural plasticity - neurons can alter their: - dendrite-to-dendrite connections - axon-to-dendrite connections - axon-to-axon connections - neurotransmitter receptor density This allows for the brain to change the way that different neural networks interconnect, and it also allows regulation and modulation of neural signals so that the "weights" between neurons are changed to remodulate those signals. Diseases, such as Alzheimer's disease, ALS, and multiple sclerosis, can also result in demyelination, which results in signal loss along axons.
How do motor neurons receive instructions from adjacent neurons?
These instructions are received in the form of an impulse stimulation of a particular protein channel on the dendrite by a neurotransmitter termed acetycholine (ACh).
A synapse consist of?
A synapse is the connection between two neurons. It consists of the synaptic cleft (the physical gap between one neuron's axon and the other's dendrite). Neurotransmitters cross the gap from the axon to the dendrite and affect whether the next neuron fires.
What are anticholinergics?
Anticholinergics are a class of medications that inhibit parasympathetic nerve impulses by selectively blocking the binding of the neurotransmitter acetylcholine to its receptor in nerve cells.
What is the advantage of having multiple receptor subtypes for a neurotransmitter?
Multiple receptor subtypes allow for more "fine-tuned" neuromodulation of a given "signal" in a neural network. Each receptor subtype typically has a different binding affinity for the given neurotransmitter. Therefore, the neurotransmitter may bind more strongly or more weakly to one subtype over another. This is most likely an effect of genetic variation, as the genes coding for the protein(s) present in the receptor slightly vary from subtype to subtype, yet still allow for binding by the neurotransmitter ligand.
The tremors of Parkinson's disease result from the death of nerve cells that produce the neurotransmitter?
dopamine
The structure that recevies an impulse from the dendrite is the?
Cell body.Impulses a received in the dendrite, go through the cell body and out to the axon, where they are transmitted to the next dendrite. Easy way to remember it, it's the alphabet backwards - Dendrite, Cell Body, Axon
What is the longest dendrite of a neuron?
the longest dendrite is I don't know this /;[
