do you think your temperature sensory neurons code this very noticeable and strong stimulus?

b) They produce larger, but the same number of, action potentials as under the warm water
condition.
c) They produce smaller EPSPS at a higher rate than under the warm water condition.
d) They produce the same number and size action potentials that travel faster down the neurons
than under the warm water condition.
e) They produce more action potentials of the same size as under the warm water condition
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
Which of the following is true regarding the difference between graded and action potentials?
a.) Action potential occur only when the surface of the neuron is myelinated, but graded potentials occur in both in both myelinated and non-myelinated neurons.
b.) The magnitude of action potential depends on the magnitude of the stimulus, whereas graded potentials are all or none.
c.) The magnitude of graded potential depends on the magnitude of the stimulus, whereas action potentials are all or none.

- In the knee jerk, contraction of quadriceps is accompanied by relaxation of the opposing flexor muscles. The contraction of quadriceps is mediated by a monosynaptic reflex (as stated above), and the relaxation of the antagonists is due to a dual connection reflex. The relaxation of antagonists is mediated by an inhibitory transmitter released by interneurones - these are called the la inhibitory interneurones, How do we name a dual connection reflex? monosynaptic disynaptic tricynaptic polysaccharidearrow_forwardSince 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?arrow_forwardWhich of the following statements about the intensity of a nerve response is true? Select one: a. A stimulus reaching the threshold level may or may not propagate a nerve impulse. b. A small voltage shift and a large voltage shift will yield the same nerve impulse as long as the stimulus reaches the threshold level. c. All stimuli, regardless of the strength, will always generate a nerve impulse. d. A stimulus resulting in a greater voltage shift will result in a stronger nerve impulse and increased sense of perception in the brain.arrow_forward
- 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_forwardConsider three alpha-motor neurons of different sizes: small, medium and large. All three neurons receive input from the same excitatory interneuron. When the interneuron fires action potentials at low frequency, only one alpha motor neuron fires action potentials. As the action potential frequency of the interneuron increases, two alpha-motor neurons are recruited, and at maximum frequency, all three are recruited. In what order would the three alpha-motor neurons have been recruited? Large first, then medium, then small. Small first, then medium, then large. Medium first, then small, then large. Medium first, then large, then small.arrow_forwardWhich of the following statements about the intensity of a nerve response is true? a.

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? Rubric: Impact of heat on A Impact of ice on A ( Impact of drug X on A Impact of drug X on B 1arrow_forward
