- What would happen to an insect if you treated an insect with a chemical that inhibits acetylcholinesterase? 1) K+ channels get stuck open and the neuron stays perminantly hyperpolarized 2) Acetylcholine would continue to activiate Ca++ channels until death by exhaustion 3) Acetylcholine would continue to activiate Na+ channels until death by exhaustionarrow_forwardWhat is the role of calcium in neuronal communication at the axon terminal? What would be prevented if calcium channels could not open here in the terminal?arrow_forward38arrow_forward
- A patient with chronic right shoulder pain has learned that the use of imagery and guided meditation has helped control his pain. A family member asks how these techniques can help with pain. The nurse replies that these therapies can slow the release of transmitter chemicals in the dorsal horn change the cognitive and affective thoughts about the pain prevent transmission of nociceptive stimuli to the brain increase the modulating effect of the efferent pathwaysarrow_forwardWhich of the following occurs when light activates a photoreceptor? Choose all that apply. Glutamate will be released The cell will be depolarized Phosphodiesterase is inactivated [Sodium ions channels will be closed CGMP is presentarrow_forwardChoose two false statements and explain why? Toxin causes voltage-gated sodium channels to open at a lower voltage toxin slows down the inactivation of sodium channels toxin causes ligand-gated sodium channels to open toxin causes voltage-gated potassium channels to open fasterarrow_forward
- What is the term used to describe the rounded lump located at the end of the axon? synapses receptor sites terminal button O synaptic vesiclesarrow_forwardOn this motor neuron, Add in and label: dendritic spines an axon collateral, with axon terminals synaptic knobs myelin on the axon and axon collateral synaptic knobs Draw arrows and label: ахon axon terminals synaptic knobs cell body dendrites and dendritic spines And draw an arrow showing the direction the action potential travels.arrow_forwardClassify the given items with the appropriate group. Neuron is hyperpolarized Occurs when voltage-gated sodium channels have returned to resting state No amount of stimulus will initiate a second action potential Ensures that the action potential moves down the axon in only one direction Voltage-gated sodium channels are opened then closed in the inactivated state Occurs about 1 millisecond after an action potential Relative Refractory Period Absolute Refractive Periodarrow_forward
- A toxin causes neurons to fire excessively. What is a possible mechanism for this effect? A) Chloride channels are blocked. This leads to less EPSPs. B) Sodium channels are blocked. This leads to less IPSPs. C) Chloride channels are blocked. This leads to less IPSPs. D) Sodium channels are blocked. This leads to less EPSPS.arrow_forwardYou apply a new drug to a different batch of neurons and record membrane potential changes in the presynaptic and postsynaptic neurons. You record an action potential in the presynaptic neuron and a change from -70mV to -90mV in the postsynaptic neuron. Your drug most likely allowed which ion into the postsynaptic neuron? Chloride GABA Glutamate Potassiumarrow_forwardResearchers have designed a neuron that's unable to produce and release neurotransmitters. Can that neuron still have an action potential? Choose the answer with the correct answer and the correct reasoning. O No, action potentials need neurotransmitters to increase message speed O No, a neuron can't receive messages without its own neurotransmitters O No, a lack of neurotransmitters would leave a neuron unmyelinated O No, action potentials don't occur in the axon O Yes, action potentials don't require neurotransmitters:arrow_forward
