Explanation:

Identify the highlighted structure

Using the Eye Anatomy and Optical Components knowledge points

• The anatomical model shows a sagittal cross-section of the eye situated within the orbital cavity.
• A bright green highlight is tracing the outermost, transparent anterior layer of the eyeball.
• This anterior, dome-shaped transparent layer that covers the iris and pupil is the cornea.
• The sclera is the white, opaque fibrous outer layer covering the posterior portion of the eye (highlighted in white/grey in the model, but not green).
• Therefore, the highlighted structure is the cornea.
