OCCTH 585 Neuro Questions With Complete Solutions. True or False: Rehabilitation specialists are able to foster functional recovery in the nervous system without knowledge of the biological basis of injury and repair. - correct answer.False It is argued that a biological basis of injury and repair is essential for rehabilitation specialists to know and understand in order to be effective healthcare providers. In simple terms, what is neuroplasticity? - correct answer.The brain'...

Which current flow listed below causes depolarization of the neuronal cell membrane? sodium efflux chloride influx potassium efflux sodium influx Correct Answers Correct answer sodium influx An EPSP ____________ the likelihood of an action potential occurring. has no effect on has an unknown effect on decreases increases Correct Answers increases A voltage-gated ion channel is opened in response to a change in the membrane potential. phosphorylation. ligand binding. All ...

CLTM ASET s #280-500 Question and answers 2024 verified to pass LH (Luteinizing hormone) is produced where? - correct answer Pituitary gland (anterior pituitary) What are the benefits of presurgical mapping in epilepsy surgery or tumor removal cases? (select all that apply) - correct answer *minimize functional deficit *provide data for intra-operative guidance and maximize resection *assess risk and benefit of surgery *plan surgical approach Why is it important to record eye movements...

What does the change in membrane voltage depend on? - ️️depends on the ion channels opened, not the neurotransmitter some neurotransmitters can have both excitatory and inhibitory effects; depends on the ligand gated channels in postsynaptic cell and the ion channels determining EPSP or IPSP When are large axons used? - ️️rapid responses- cockroach startle/escape response; sensory filiform hair receptors on back synapse to giant axon that goes to thoracic region and then synapses ...

Step 1: The Chemical Synapse An action potential arrives at the end bulb. Step 2: The Chemical Synapse Ca++ enters the presynaptic terminal. Step 3: The Chemical Synapse Ca++ interacts with the synaptic vesicle and fuses with the presynaptic membrane. Step 4: The Chemical Synapse Neurotransmitter is released and binds to the postsynaptic transmitter receptor. Step 5: The Chemical Synapse Receptor protein undergoes a change in shape that allows ions to flow. Step 6: The Chemical Synapse...

NSC Chapter 5 Test with Complete Solutions transporters - Answer-special proteins embedded in the vesicle membrane that concentrate neurotransmitters inside the vesicle once the amino acid and amine neurotransmitters are synthesized in the cytosol and then taken up by the synaptic vesicles. voltage-gated calcium channels - Answer-following the depolarization of the terminal membrane, these channel proteins open and let in Ca++ ions; resulting elevation in the ions is the signal that causes n...

How Neurons Integrate Information- Through dendritic spines, a neuron can establish more than 50,000 connections to other neurons - Nerve impulses traveling from other neurons bombard the receiving neuron with all manner of inputs (excitatory and inhibitory) - The cell body, located between the dendritic tree and its axon, can receive inputs from many other neurons Saltatory ConductionMyelin and Node of Ranvier Node of RanvierPart of an axon that is not covered by myelin Tiny gaps in the myeli...
