Multiple sclerosis (MS) is a disorder that causes the destruction of myelin sheaths surrounding
neurons. People with MS display many symptoms, including slurred speech, double vision, and
poor muscle coordination.
What is the direct effect of MS on nerve impulse transmission?
Select one:
The movement of impulses along neurons is
slower than normal.
Dendrites cannot be stimulated by acetylcholine,
therefore impulses are not generated in neurons.
The threshold level of stimulation for neurons is
greater than normal.
Axons cannot sectete acetylcholine, therefore
impulses are not able to travel across synapses.
O
Since at any moment a neuron is likely to have thousands of neurons releasing neurotransmitters at its surface, how is neuronal activity (to fire or not to fire) determined?

reflex arc in the order in which nerve signals

- A laboratory experiment is set up where you have two fully functional nerves properly aligned so that it potentially can transmit an action potential through a synapse to the second nerve. The buffer outside the cells contain Na+, H+ and Cl- as the only inorganic ions. When you stimulate the nerve, surprisingly the second nerve does not respond. What is the most likely explanation for the failure of the second nerve response? State why you chose your answer. a. The lack of K+ in the buffer prevents propagation of the action potential b. Neurotransmitter is not being released into the synaptic space. c. An action potential can only be initiated by opening a ligand-gated channel. d. Although neurotransmitter is released, it is unable to stimulate opening of the second nerve' ligand-gated channel. e. Repolarization of the axon does not occur in this buffer.arrow_forward2) The correct order of a reflex arc is: a) sensory neuron, sensory receptor, interneuron, motor neuron, effector b) sensory neuron, sensory receptor, interneuron, effector, motor neuron c) sensory receptor, sensory neuron, interneuron, motor neuron, effector d) sensory receptor, sensory neuron, interneuron, effector, motor neuronarrow_forwardYour best friend, Reg, was walking through the forest when they found some particular delicious looking mushrooms. Thinking they know all about mushroom safety, they promptly set up their camp stove and cooked and ate a mushroom omelette. Shortly afterwards, they begin to feel body numbness, blurred vision, and lack of coordination. An unknown toxin from the mushroom is affecting the action potential (AP)! Using your knowledge of action potentials (M1L3), please answer the following questions below. Be sure to clearly label the different parts. Part A. Describe the processes that take place during AP initiation and identify the channels involved. Part B. If the toxin is making it harder to initiate an AP, what might be happening to the voltage-gated channels ? Part C. What do you predict lowering the resting membrane membrane potential (making it more negative) would do to AP initiation? Explain your reasoning.arrow_forward
- Alcohol addiction is a condition in which a person experiencesdependent on alcohol and difficult to control its consumption. On the other hand, excessive alcohol consumption in the long term can cause disturbances in brain performance, including disturbances in memory, attention, coordination, and locomotion. How does alcohol affect the functioning of nerve cells and the central nervous system? What is the mechanism that occurs? Based on information from the literature, analyze what will happen to coordination and locomotion in someone who is addicted to alcohol and consumes large amounts of alcohol over a long period of time.arrow_forwardNeuron A is an inhibitory neuron that is activated when the person feels heat in the tip of their index finger. Neuron A sends signals to neuron B (the postsynaptic neuron). First consider how a stimulus impacts the firing rate of neuron A. For example, when the person touches ice with their index finger vs. when the person touches a hot cup of coffee with their index finger? How would each of these impact the frequency of action potentials, the size of action potentials and the amount of neurotransmitter released. Second, consider Drug-D that causes all sodium channels in neurons to close immediately. How would taking Drug-D affect the firing rate of neuron A when the person touches a hot pan? In turn, how would this affect the firing rate of post-synaptic neuron B?
