Vedclass · Answer

(A) Fovea centralis is the area of the most acute vision on the retina.In this region,the ratio of photoreceptor cells (cones) to bipolar cells to ganglion cells is $1:1:1$.This specific arrangement allows for high visual acuity because each cone cell has a dedicated pathway to the brain,minimizing signal convergence.Therefore,the Assertion is correct and the Reason provides the correct explanation for it.

$A$: Sharpest vision is in fovea centralis.
$R$: The relationship of receptor to bipolar cells to ganglion cells is $1:1:1$ within fovea centralis.
