Structure number 4 has a larger diameter than structure number 2. b. Structure number 4 does not have myelin sheaths. c. Structure number 3 does not have myelin sheaths. d. Structure number 3 has a larger diameter than structure number 4.

37) Multiple sclerosis is a disease in which the body attacks its own nervous system and specifically affects the myelin. Its many symptoms include a person having a reduced sense of touch. Explain how the disease effects the conduction of information and what class of neurons appears to be affected to cause this symptom.
The diagram below indicates different ion concentrations from the inside to the outside of a neuron while the neuron is at rest. A. Use the different colour to indicate the sodium ions, potassium ions, sodium ion channels, and potassium ion channels. B. Also indicate the charge inside and outside the neuron. Your answer NUNUNU extracellular fluid cytoplasm
Neurons are highly specialized cells whose form matches their function. They are highly elongated cells that conduct [Select ] a. ["electrical", b. "chemical"] signals across large distances, and [ Select ] ["chemical", b. "electrical"] a. signals across tiny spaces between neurons called [ Select ] a. ["hillocks", b. "Summations", c. "synapses"] . Neurons use vast amounts of energy to maintain the [Select] a. ["polarization", b."resting membrane potential", c. "action potential through the actions of [ Select ] a. ["sodium-potassium pumps", b."voltage-gated sodium channels", c."voltage-gated potassium channels"] . In doing so both sodium and potassium are trafficked against their concentration gradients leading to high concentrations of sodium [Select ] a. ["inside" , b. "outside"] the cell, and high concentrations of potassium [ Select ]
During an Action Potential….. _____ Na+ flows out of the cell _____ Na+ activation gates and inactivation gates are both open _____ Na+ flows into the cell _____ Calcium flows out of the cell _____ K + gates are open _____ Na+ activation gates are closed _____ Na+ inactivation gates are closed _____ K+ flows into the cell _____ K + gates are closed _____ Na+ activation gates and inactivation gates are both closed _____ K + flows out of the cell

The graphs represent a membrane potential recording from a hair cell (graph A) and a neuron it synapses with (graph B) in response to a small stimulus at the time indicated by an arrow. Explain how each graph would change in response to a stimulus of much greater intensity and why
Match the description with the statement that best describes the following regions synaptic knob axon hillock dendrites axon A. elongated projection that conducts electrical signals over long distances B. receives input from other neurons C. region of high denisty of voltage-gated channels, known as the trigger zone D. contains numerous vesicles containing neurotransmitter
Think about how the neuron membrane-capacitor works – via the motion of charged ions from inside-to-outside and outside-to-inside the cell. Describe phenomenologically how you think the membrane potential can be made to propagate down the length of a neuron. Draw some diagrams to aid your description.
Fluorescent FM dyes partition reversibly into biological membranes without penetrating through them. Suppose that you have neurons cultured in a dish, and you incubate them with an FM dye for a period of time before washing the cells with excess medium to remove the dye. a) You find that if you stimulate the neurons to trigger action potentials during incubation with the dye, the synaptic regions of the neurons remain fluorescent after the wash. Propose an explanation for this effect. b) After you have generated fluorescent synaptic regions by this procedure, suppose that you trigger further action potentials while continuing to wash with excess medium. Would you expect the synaptic regions to lose fluorescence? Explain.
