What is the difference between retinal, opsin, and rhodopsin?
Step by step
Solved in 3 steps
- The correct pathway of activation (by sending neuronal signals) in the retina is bipolar cell - retinal ganglion cell - photoreceptor photoreceptor - retinal ganglion cell - bipolar cell retinal ganglion cell - bipolar cell - photoreceptor photoreceptor - bipolar cell - retinal ganglion cell O bipolar cell - photoreceptor - amacrine cellYou are watching the stars at night, and you never seem to be looking at the right spot to catch the brightest meteors. Which of the following might explain this? a)Your fovea contains mostly cones; thus you see dim light especially well when looking right at it. b)Your peripheral retina contains more rods, which are more sensitive to dim light than cones; thus objects in your peripheral vision appear brighter in dim light situations. c)Detection of light depends mostly on its color rather than intensity; thus cones play a larger role in detection of light in dim light situations. d) all of the above. ( well explain the correct answer and type answer).Describe the process of retinal transduction. How are visual cues perceived at the cellular level?
- 47. Which of the following regions of the retina is capable of the highest spatial resolution and color sensitivity? A) Lamina cribrosa B) Limbus C) Macula lutea D) Optic papilla E) Ora serrata7. From back to front, the order of the cells in the retina are... A) Ganglion cells, photoreceptor cells, bipolar cells B) Photoreceptor cells, ganglion cells, bipolar cells C) Photoreceptor cells, bipolar cells, ganglion cells D) Ganglion cells, bipolar cells, photoreceptor cellsWhat are the receptor cells in the eye that are most sensitive to light and that give an image in black / white (grayscale)?
- What is the primary role of rod cells, and what are the two roles of cone cells in the retina?What is the function of Color Vision?Even though they are located in the back of the retinal tissue, what is the importance of the rod and cone photoreceptor cells to our sense of sight? (explain elaborately)
