Question
Discussion:. In 1-2 well-formulated and coherent paragraphs discuss the findings of the experiment as it relates to and the size principle. (To examine the results for your discussion think about: What does the noted differences in response periods based on the level of stimulus indicate about the stimulation of the nerve? Compare individual nerv those of the group avera and latency conduction results with ge. What rationale can you provide for needing to determine the differences between the responses at Threshold d Potentials when determining the nerve conduction velocity? Why do you use the difference in latency period between sites and not between the maximal and threshold potentials when determining nerve conduction velocity for your test subjects? Compare individual nerve conduction results with those of the group average. Would you expect a difference in observations in nerve conduction velocity if the test subject's Right ulnar nerve were used as opposed to the Left ulnar nerve that was utilized here? Why, or why not?) Conclusion: What can you conclude about the conduction velocity? Restate hypothesis based on the findings of your experiment as a factual statement. Link to future experiment: what do you think would happen if we don't allow for the subject to recover and remove the stimulator from the ulnar nerve? Relate to the nerve's potential when mechanically compressed that provides a rationale for why one might state that their "foot" has fallen asleep if seated for a prolonged period of time.Explanation / Answer
Latency refers to the interval or division of time for regular occurrence of phenomenon.The term latency specify the action potential(AP) generated across nerve or muscle fibre membrane,also called nerve conduction velocity.i.e electrical impulses are generated by means of action potential in different latency periods.
Conduction velocity is very specific and depends on axons diameter and the degree to which that axon is myelinated.
threshold potential referred as the detection of minimum value of a sensory stimulus needed to generate action potential.i t can simply be said minimum force required to cause cell excitability.
SIGNIFICANCE:it is a measure from a stimulator where voltage generated to one action potential from a sciatic bundle nerve.-50 and -55mv
Maximal threshold specify the range above threshold value.
We use Latency period between sites not between threshold potentials because potential are generated by the flow of electrical impulses and that could be between any of the sites either in nerve fibre muscle fibre.potentials are a measure of action potential that vary depending on several factors.
Absolutely no difference is observed with handedness.it ranges velocities in motor nerve (P>0.05).
CONCLUSION: conduction velocity is very specific.i t is a speed that allows electrical impulses to generate action potential.
If we don't allow the subject to recover,or no stimulus it means the body is dead or semi coma,if no impulses are generated.
If one s foot is asleep for a prolonged period of time,it is subjected to too much of pressure,where brain nerves cannot trasmit sensations beyond its optimal value.In such conditions brain function s very slow.later if relaxed,blood circulation flow allowing electrical stimulus to generate action potential.
