6. Which muscle is contained within the iris stroma?

  • Sphincter Pupillae
  • Dilator Pupillae

7. In the iris during pupil constriction/dilation which zone's width alters the most?

  • Ciliary Zone
  • Pupillary Zone

8. The iris epithelium appears black, why is this?

  • The whole whole layer is deeply pigmented
  • There is an absence of light
  • It is in the shadow of the ciliary body

9. Which layer of the ciliary epithelium is pigmented

  • The superficial layer
  • None of the layers
  • The underlying layer
  • All layers

10. There are two layers of the Basal lamina (Bruch's membrane), the cuticular lamina and an exterior elastic layer

  • True
  • False

11. The pars plicata of the ciliary body is...?

  • The further anterior region which is flat
  • The flat, posterior region
  • The further anterior portion which features many ridges
  • The posterior region which features the ciliary processes

12. Where do the veins in the choroid drain to?

  • To the anterior half of the globe, into the four vortex veins which eventually drain into the superior and inferior ophthalmic veins
  • To the posterior half of the globe, into the four vortex veins which eventually drain into the superior and inferior ophthalmic veins
  • To the posterior half of the globe, into the four vortex veins which eventually drain into the superior and inferior ophthalmic arteries
  • To the anterior half of the globe, into the four vortex veins which eventually drain into the superior and inferior ciliary veins

13. There are two layers of the Basal lamina (Bruch's membrane), the cuticular lamina and an interior elastic layer

18. What is the supraciliaris

  • The outer layer of the ciliary body which lines the sclera
  • The Latin name for the ciliary processes
  • The capillary network inside the ciliary muscle

19. Where does the innervation for the sphincter and dilator pupillae muscles come from?

  • The Oculomotor (V) nerve, and cells in the superior cervical ganglion, respectively
  • The Oculomotor (III) nerve, and cells in the Superior cervical ganglion, respectively
