Title: A neuron was isolated from structure number 3 in the diagram above. When comparing the velocity of Post by: ohemati on Apr 28, 2020 28. A neuron was isolated from structure number 3 in the diagram above.
When comparing the velocity of action potentials, structure numbered 3 is much slower than that of structure numbered 4. Which of the following explains why this is? See attached pic for the diagram Select one: a. Structure number 3 has a larger diameter than structure number 4. b. Structure number 4 does not have myelin sheaths. c. Structure number 3 does not have myelin sheaths. d. Structure number 4 has a larger diameter than structure number 2. 27. When a single photon from a source of light hits the retina in the eye, it triggers a signal that travels along the optic nerve to the occipital lobe of the brain. The interaction of a photon with the photoreceptors in the retina first causes the movement of sodium ions into a sensory neuron. What happens after the movement of sodium ions? Select one: a. Sodium ions move out of a sensory neuron. b. Potassium ions move into an interneuron. c. Potassium ions move out of a sensory neuron. d. Sodium ions move into an interneuron. my answer is c but not sure if its correct or not Title: Re: A neuron was isolated from structure number 3 in the diagram above. When comparing the ...

Structure number 3 does not have myelin sheaths. d. Structure number 4 has a larger diameter than structure number 2. I believe it's c. Structure number 3 does not have myelin sheaths. The next one is a tough one for me: https://videos.homeworkclinic.com/watch/98/neuron-type-animation/ https://videos.homeworkclinic.com/watch/227/the-nerve-impulse/ Given what I take from these two videos, I feel the answer should be D, but I don't understand what they're asking to be honest. Because the flow goes from sensory > interneuron > motor neuron. You can decide on this. I see what you mean by choosing (C), yes potassium depolarizes the cell by coming out of the neuron, but is this what they're asking?
