Across
- 4. Transparent mucous membrane covering the anterior eyeball surface. (Page 547)
- 6. eye muscles Control eye movements and maintain eyeball shape. (Page 548)
- 8. Adjustment of retinal sensitivity when transitioning from bright light to darkness. (Page 567)
- 11. Midbrain structure involved in visual reflexes and eye movement coordination. (Page 565)
- 13. Chiasma X-shaped structure where optic nerve fibers partially cross over. (Page 564)
- 14. Area in the occipital lobe where conscious visual perception occurs. (Page 566)
- 15. Anteriorly protect the eyes; separated by the palpebral fissure. (Page 546)
- 16. pathway carrying visual information from the lateral geniculate nucleus to the visual cortex. (Page 565)
- 17. Adjustment of retinal sensitivity when transitioning from darkness to bright light. (Page 567)
- 18. gland Produces tears that moisten and cleanse the eye. (Page 548)
- 20. Neural processing of visual information from rods and cones to higher visual areas. (Page 567)
Down
- 1. Midbrain nucleus involved in mediating pupillary light reflexes. (Page 566)
- 2. Tough, opaque layer protecting the eye; continuous with the dura mater of the brain. (Page 549)
- 3. Gel-like substance filling the posterior segment of the eyeball; maintains eye shape. (Page 550)
- 5. Ability to perceive spatial relationships between objects in the visual field. (Page 566)
- 7. Transparent structure allowing light to enter the eye; part of the light-bending apparatus. (Page 549)
- 9. Fluid filling the anterior segment of the eyeball; helps maintain intraocular pressure. (Page 550)
- 10. Thalamic nuclei where visual information from the optic tracts is processed and relayed. (Page 565)
- 12. Thickened ring of tissue encircling the lens; contains ciliary muscles. (Page 549)
- 19. Adjustable focusing apparatus of the eye; held in place by the ciliary zonule. (Page 549)
