Question

Hello pls answer all the 19 questions I really need help with all of them this is neuroscience I can't find the option for this subject here

1. The optic tract on the right side of the brain contains axons from the left eye only.

True

False

2. Olfactory receptor neurons (ORNs) are unipolar cells whose axons project directly to the olfactory bulb.

True

False

3. The left optic nerve contains axons from the left eye only.

True

False

4. Olfaction is mediated by ionotropic mechanisms.

True

False

5. Identifying the color of a bird in a tree would involve your P-type ganglion cells.

True

False

6. The sense of olfaction must go to the thalamus first before going to other structures such as the cortex or the hypothalamus.

True

False

7. When Golf is stimulated, adenylyl cyclase is activated which leads to the formation of cGMP.

True

False

8. The superior colliculus plays a role in the biological rhythms, including sleep and wakefulness as a nonthalamic optic tract target.

True

False

9. The cornea is the site of the most refractive power of the eyes.

True

False

10. If I shined light into your left eye, your right pupil would constrict as well.

True

False

11. Parvocellular LGN neurons project to layer IVCalpha while magnocellular LGN neurons project primarily to layer IVCbeta.

True

False

12. Salty and Sour utilize G proteins in the prorcess of sensory transduction.

True

False

13. The ventral stream goes through area MT and eventually reaches the parietal lobe.

True

False

14. Tastants are the chemical constituents of food.

True

False

15. Cranial nerve 7 sends information to the caudal nucleus of the solitary tract.

True

False

16. Depolarization in olfactory cells is caused by an influx of Chloride ions.

True

False

17. The stimulation of phospholipase C leads to increased production of IP3 which then allows for Cl- to exit the taste cell.

True

False

18. When you eat something sour, H+ blocks special channels selective for sodium.

True

False

19. Cones are more concentrated in the peripheral retina while rods are more concentration in/around the fovea.

True

False

Explanation / Answer

Answer1

False

Because the optic tract contains the axons from both the eyes

Answer 2

True

Because the ORN is now depolarized and this signal travels through the dendrite, through the soma and via the olfactory nerve to the olfactory bulb

Answer 3

False

Because The right optic nerve receives visual information originating in the left optic nerve & the optic tract contains the axons from both the eyes

Answer 4

True

Because Signal transduction in the olfactory receptor neurons in humans is based on Ionotropic

Answer 5

True

Because it project parvocellular layer on LGN which help in colour detection

Answer6

False

Because it travels directly to the forebrain without going to the thalamus.

Answer 7

False

Because it activate cAMP

Answe 8

True

Because LATERAL GENICULATE NUCLEUS SUPERIOR COLLICULUS ACCESSORY OPTIC TRACT

Answer 9

True

Because due to the differences in the indices of refraction between the air and the aqueous humor

Answer 10

True

Because When one eye is exposed to light, the pupils in both eyes constrict.

Answer 11

False

Because Parvocellular LGN neurons project to IVCbeta.

Answer 12

True

Because g protein activates cAMP

Answer 13

False

Because dorsal stream reaches Parietal lobe

Answer 14

True

Because this is taste provoking chemical in the food

Answer15

False

because nerve travel to the from the pons in the temporal bone

Answer 16

False

Because it is exflux by chloride ions

Answer17

True

Because IP3 acts to release Ca2+ from the endoplasmic reticulum

Answer 18

True

Because high concentration of sodium leads to saltiness

Answer19

False

Because cones are more concentrated in fovea
