Question

1. what covers the inner surface of the ciliary process?

○ pars optica
○ pars ciliaris
○ pars erratica
○ pars myopia

1. the _______ is devoid of rods and cones and hence is referred to as the blind spot.

○ macula
○ retina
○ optic nerve
○ fovea

Explanation:

Question 90

To solve this, we recall the anatomy of the ciliary process. The inner surface of the ciliary process is covered by the pars ciliaris (part of the retina's ciliary part). Pars optica is the neural retina, pars erratica is not related, and pars myopia is not a term for this structure.

We know that the optic nerve head (where the optic nerve exits the eye) has no photoreceptors (rods and cones), making it the blind spot. The macula has cones (fovea is part of macula), retina has photoreceptors, and fovea has dense cones. So the optic nerve region (optic disc, part of optic nerve) is the blind spot.

Answer:

B. pars ciliaris (assuming the options are labeled A, B, C, D with A: pars optica, B: pars ciliaris, C: pars erratica, D: pars myopia)
