Students have asked these similar questions
a channel can be gated mechanically, voltage
or by a ligand. When you hear a sound all three of these type channels are being
utilized. Explain generally where/how each of these channels are being utilized
starting from hearing the sound, through travelling down a nerve to transmission
to another nerve.
Applying a pressure stimulus to the fluid-filled capsule of an isolated Pacinian corpuscle causes a brief burst of action potentials in the afferent neuron, which ceases until the pressure is removed, at which time another brief burst of action potentials occurs. If an experimenter removes the capsule and applies pressure directly to the afferent neuron ending, action potentials are continuously fired during the stimulus. Explain these results in the context ofadaptation.

- When they are not being stimulated, neurons have an electrical charge across their membranes called the resting potential. This potential is______ charged inside. When a neuron receives a sufficiently large stimulus, and reaches a potential called the_______ , it produces an action potential. This causes the neuron to become_____ charged inside.arrow_forwardYou and your lab partner have prepared a frog nerve for gathering data on action potentials. You connect an electronic stimulator to the nerve and ask your partner to gradually increase the voltage until you see an action potential. Your partner says that the voltage knob is stuck and will not increase the voltage. To finally get an action potential, they begin to trouble shoot and instead of increasing the voltage, they begin to simulate the nerve over and over again and see an action potential. What type of summation is this describing? action potentials graded potentials spatial summation temporal summation O thresholdarrow_forwardthe bacterium clostridium tetani produce a toxin called tetanospasmin, the causative agent os the disease tetanus. the toxin prevents the release of inhibitory transmitters in the CNS and so blocks the resulting IPSPs they would normally generate. what are some of the functions of inhibitory synapses? considering this what symptoms would you expect from the disease tetanus, and why? ( hint: imagine trying to stand up if all of the muscles in your lower limb contracted at the same time.)arrow_forward
- In what way does the interior surface of the cell membrane of a resting (non-conducting) neuron differ from the external environment? The interior is: positively charged and contains less sodium. negatively charged and contains less sodium. negatively charged and contains less potassium positively charged and contains more sodium.arrow_forwardIdentify and label the following structures on the neuron model figure below: cell body, dendrites, neuron nucleus, neurolemma, axon hillock, nucleus of Schwann cell, Nissl bodies, myelin sheath, axon, node of Ranvier, axon terminals (of neurons synapsing with model neuron), endoneurium (refer to Figure 10.6). 3) 11arrow_forwardexplain the simplified version of the synaptic process resulting in long-term potentiationand explain the roles of AMPA and NMDA receptors; glutamate; sodium, calcium, and magnesium ions in strengthening a synapse.arrow_forward
- Somatic sensory and somatic motor information are propagated via specialized neurons. If you dip your toes in a hot tub before entering the tub, the action potentials generated by the water temperature travels via which of the following structures before it can be perceived by you?

- Two separate post-synaptic interneurons receive synaptic potentials from afferent neurons in the periphery. The dendrites of one these interneurons receive an excitatory post-synaptic potential (EPSP) and an inhibitory post-synaptic potential (IPSP) of equal magnitude at the same time. The dendrites of the other interneuron receive one excitatory post-synaptic potential that is the same sized as the EPSP and IPSP received by the other interneuronarrow_forward1) The interior of an axon at rest is negatively charged relative to the outside is positively charged relative to the outside has the same charge as the outside has the same concentration of potassium (K+) as the outside 2) The branch-like portions of a neuron that carries information toward the cell body is the axon. dendrite. terminal button. soma.arrow_forwardWhich 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.arrow_forward
