What determines the frequency of action potentials in the axon of the sensory neuron R2. If you were to spend a lot of time studying nerve physiology in the laboratory, what type of stimulus would you use, and why.
Describe what happened when you applied a strong stimulus to the sensory receptor. All of the above play a role in determining the amount of neurotransmitter released. What determines the amplitude of the depolarization at the sensory receptor R1.
Which of the following directly or indirectly determines the frequency of action potentials in the axon of the interneuron.
What is myelin and how does myelination affect nerve conduction velocity. The amount of calcium that enters the sensory receptor. Provide the generic name and brand name of 3 other local anesthetics. Please has a double space from the end of one question and the beginning of the next question.
Provide a good and brief physiological explanation.
How well did the results compare with your prediction. You may type your answers. Give a clean report Related Essays. In activity 7 you tested the effect of lidocaine on eliciting an action potential.
Identify the type of membrane potential graded receptor potential or action potential that occurred at R1, R2, R3, and R4 when you applied a moderate stimulus view Experiment Results to view the response to this stimulus. Review Sheet Results Why is the resting membrane potential the same value in both the sensory neuron and the interneuron.
There was a small depolarizing response at R1 with no responses occuring at R2-R4, as predicted. How this explains the analgesic effect of lidocaine. The amplitude of the depolarization at the sensory receptor R1.
The statement of the questions should be included in the report. What is the relationship between size of a nerve and conduction velocity. Describe what happened when you applied a very weak stimulus to the sensory receptor. All of the above play a role in determining the frequency of action potentials in the axon of the interneuron.
Weak 0 0 0 Moderate You would use a electric stimulus, this is because with the electric stimulus you can adjust and determine the pressure, frequency, duration, and voltage and control them. How to write this report. Myelin is a mix of proteins and phosopholipids which creates a sheath around nerve fibers which will then increase the speed of conduction.
Membrane irritability is the ability to respond to a stimuli and convert it in to nerve impulses. Which of the following directly determines the amount of neurotransmitter released at the axon terminal of the sensory neuron. Membrane conductivity is the ability to transmit that impulse that is created by membrane irritability.
The larger the myelination the larger the gap of the channels is, the farther the signal can jump at a more rapid speed. What would be the effect of inhaled ether on the generation of action potentials in neurons in the brain of a rat exposed to this anesthetic.
The larger the size of the nerve it creates a lesser amount of resistance that the ions need to travel the lesser amount of resistance will increase the conduction velocity. List three 3 common use of lidocaine. The PhysioEx was everything they said it would be before I purchased it.
