Question

activity 17: quiz
module: nervous
topic: structures / type: combination

what structure is highlighted?

a. corneoscleral junction
b. choroid
c. retina
d. posterior cavity
e. cornea

Explanation:

Identify the highlighted structure

Using the Eye Anatomy and Retina Anatomy knowledge points

• The histological cross-section of the eye shows several color-coded structures:
• The green layer at the anterior represents the cornea.
• The red structure represents the lens.
• The blue outer layer represents the sclera.
• The thin pink/magenta layer lining the posterior inner surface of the eye represents the retina.
• The highlighted layer in pink/magenta is the innermost nervous tunic of the eye, which is the retina.

Match with options

Using the Ocular Histology knowledge point

• Option A: Corneoscleral junction (limbus) is located at the transition between the cornea and sclera.
• Option B: Choroid is the middle vascular layer (not highlighted here).
• Option C: Retina is the highlighted pink/magenta inner layer.
• Option D: Posterior cavity is the large space behind the lens.
• Option E: Cornea is the anterior transparent layer (highlighted in green).
• Therefore, the highlighted structure is the retina.

Answer:

• A. Corneoscleral junction
• B. Choroid
• C. Retina (Correct answer)
• D. Posterior cavity
• E. Cornea
