Four research teams measured the speed at which signals travel down a certain type of nerve fiber, and what each team wrote in its team notebook is shown inthe table below.Suppose a later and more reliable measurement gives 111 m/s for the signal speed in the same type of nerve fiber. Decide which of the earlier measurementswas the most accurate, and which was the most precise.what was writtenmost accuratemost preciseteamin the notebook?measurementmeasurementA"101.m/s"В"91.m/s + 5.0m/s"C"131.m/s + 2.0%"D"between 106.0m/s and 126.0m/s"

Which 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.
Given what you already know about the sensation of pain, what is the expected change in membrane potential when pain is felt by sensory receptors? Select one: a. The nerve impulses increase in strength and lower the threshold potential. b. The nerve impulses occur more frequently, thereby transmitting more action potentials according to the intensity of pain. c. The nerve impulses occur more frequently and prevent neurons from entering the refractory period. d. The nerve impulses increase in strength, thereby making the maximum membrane potential higher than normal.
What is action and resting potential and how does it work in conducting electrical impulses? Please provide an accurate and onpoint answer.
Which of the following are mechanisms of gustation transduction? Select one or more: a. Hydrogen atoms activate proton channels b. Sodium ions activate sodium channels and a graded potential is produced c. Entry of sodium and calcium causes the cell to depolarize and voltage-gated calcium channels to open d. Calcium ions activate calcium channels and a graded potential is produced
For you to see the words on your compute, quite a few different types of neurons are required. what types of neurons are involved in signal transmission for you to see the words? Describe all the neural structures fro required for seeing.
To treat patients during the acute phase of opioid withdrawal, clinicians may use NSS-2 Bridge device, which is a small electrical nerve stimulator that is placed behind the person's ear and emits electrical pulses. True or False
Students in a veterinary school are given the following hypotheticalproblem: A dog ingests organophosphate poison, and the students areresponsible for saving the animal’s life. Organophosphate poisons bindto and inhibit acetylcholinesterase. Several substances the studentscould inject include the following: acetylcholine, curare (which blocksacetylcholine receptors), and potassium chloride. If you were a studentin the class, what would you advise to save the animal?
Which of the following is incorrectly matched with its function?
You fill up the tub to take a hot bath, but the water istoo hot. You test it a second and third time within a fewseconds, and it feels okay. Which of the following is themost likely explanation?a. The water has cooled down unusually quickly.b. Your ability to sense heat has adapted.c. Your nervous system is suddenly not functioningproperly.d. Someone added ice cubes to your bath.
What did Galvani's first round of frog experiments demonstrate? A. Nervous tissue is reactive in the presence of no metal B. Natural electrical properties existed within the nerve that allow for muscle contraction C. Muscle contraction is dependent on the distance between the nerve and 2 metals D. Only man-made elecricity could activate a nerve
A muscle cell contains acetylcholine receptors that act as ligand-gated cation channels,and it also contains voltage-gated Na+ channels of the type found in neurons. Intheory, could a muscle cell get away with having only acetylcholine-gated cationchannels, which would serve the dual purpose of receiving neurotransmitter signalsand propagating action potentials? Why or why not?
Many neurotoxins have been used extensively in physiological studies of neurons. When comparing tetrodotoxin found in puffer fish and batrachotoxins from poison dart-frogs, the former had no effect on a neurons resting potential but completely stopped its action potential, whereas the later toxin immediately initiates depolarization of a neuron but prevents repolarization. Can your group hypothesize how these toxins affect the nerve transmission differently?
