- In an inhibitory GABA-ergic response GABA binds ligand-gated Cl- channels which causes depolarization of the post-synaptic cell GABA binds ligand-gated Na+ channels which causes depolarization of the post-synaptic cell GABA binds ligand-gated Cl- channels which causes hyperpolarization of post-synaptic cell GABA binds ligand-gated Na+ channels which causes hyperpolarizationThe refractory period goes from "absolute" to "relative" when: The inactivation gate of Na+ channels opens up. The inactivation gate of Na+ channels closes. K+ channels begin to open. K+ channels begin to close.You are doing a nerve conduction velocity test as shown in the diagram. If the test is performed on a multiple sclerosis patient whose myelinated axons are attacked, how would the conduction velocity differ from that recorded from a normal healthy person? Nerve Monitor Nerve Conduction Velocity Test (NCCV Test) conduction velocity will be faster in the patient. conduction velocity will be slower in the patient. O only the conduction of autonomic nerve is affected. O other:
- O temporal lobe-visual processing O occipital lobe-control of skeletal muscles O frontal lobe-decision making Question 36 Which of the following must happen for long-term potentiation to occur in the hippocampus? O the postsynaptic cell responds to glutamate by opening AMPA receptors O the presynaptic cell must grow more axon terminals to synapse with the dendrites of the postsynaptic cell a presynaptic neuron must release more acetylcholine neurotransmitter into the synapse NMDA receptors must be unblocked so that they can respond to glutamate Question 37 The doctor informs you that your grandmother's stroke has caused damage to Wernicke's area. Which activity is likely to become her?Interneurons :-a- provide communication between the central ends of afferent neuronsb- provide communication between dendrites of the efferent neuronsc- influence the rate of discharge from the alpha motor neuronsd- participate in ascending sensory pathwaysWhat is the main source of the electrical potentials recorded from the scalp of a human subject? In other words, what are brainwaves /EEG? The natural current found in skin The movements of our eyes The summated activity of nerve cell action potentials and postsynaptic potentials The signals generated by the contraction of muscle fibers that lie under the scalp 2) A hyperpolarization/inhibition would be caused by which of the following? opening of chloride channels closing of chloride channels opening of sodium channels closing of sodium channels
- The falling phase of the action potential is due to: Na+ influx through voltage-gated Na+ channels. O Na* efflux through voltage-gated Na* channels. OK* influx through voltage-gated K+ channels. O K+ efflux through voltage-gated K channels. O Nat influx through Na* leak channels. Na efflux through Na+ leak channels. O K+ influx through K+ leak channels. O K+ efflux through K+ leak channels.Epilepsy is a condition which results in seizures stemming from excessive or abnormal activity of neurons. This can occur either from hyperexcitability of excitatory neurons, or impairment of inhibitory neurons. That is to say, either the excitatory pathways become overactive, or the inhibitory pathways, designed to temper the excitatory pathways, are not active enough. Much of the research done on epilepsy focuses on voltage-gated sodium channels, and to date over 700 different mutations to the channel have been identified as playing a role in epilepsy. The means by which these mutations contribute to epilepsy is quite complex, but for the sake of this CAL, let's simplify and apply what we have learned so far to identify potential mechanisms for this condition. In what way could voltage-gated sodium channels be affected in excitatory neurons which would increase the likelihood of the neuron firing an action potential? (one correct answer) The inactivation gate is slower to close. The…Describe how neurons communicate. To do this you must address: resting membrane potential; graded potentials; IPSPs; EPSPs; the role of sodium, potassium and calcium; generation of an action potential; inotropic vs metabutropic receptors; why is an AP only one direction; how are neurotransmitters released; continuous vs saltatory conduction; spatial vs temporal summation.
- In the parasympathetic nervous system, what neurotransmitter is released on the target organ? What sort of receptor detects the neurotransmitter? I was thinking the answer would be possibly acetylcholine as the first one and the second one maybe muscarinic? I am not 100% on these answers soo if you could add some information and tell me if that's right.Why do voltage-gated sodium channels have three states (open, closed, refractory/open-block)? Select all that apply. Select one or more answers and submit. For keyboard navigation... SHOW MORE ✓ a b с Multiple answers: Multiple answers are accepted for this question d To keep action potentials from going backwards To speed up the refractory period To prevent the channels from opening during repolarization To allow hyperpolarization to occur Answered ResubmitWhat is the difference between an action potential and a synapse? (select all that apply) The action potential moves down the axon and a synapse is between neurons. The synapse travels long distances and the action potential can only travel short distances. The action potential starts at the dendrites and the synapse starts at the ахon. The action potential is always the same and the synaptic potentials vary. the action potential involves only the postsynaptic neuron, but the synapse involves both the pre- and post-synaptic neurons.
