Web14. apr 2024 · Toward the periphery, the angle between a cone cell body and its outer segment can be as great as 40° ( Laties, 1969 ). All photoreceptors are oriented based on position, though the tilting is more significant in cones, perhaps due to the decreased sensitivity of cone cells compared to rods ( Ingram et al., 2016 ).
