The Senses
Across
- 1. The middle layer of the eyeball
- 2. The fluid-filled complex maze of three spaces in the temporal bone
- 6. Mucous membrane that lines the eyelids and covers the sclera
- 8. Tube that connects the throat with the middle ear to equalize air pressure on both sides of the tympanum
- 10. The jelly-like fluid found in the eye, posterior to the lens
- 11. A watery fluid that fills the bony labyrinth of the ear
- 12. Cells a taste
- 13. Disorder characterized by elevated pressure in the eye
- 14. Eardrum
- 16. Farsightedness
- 17. a membranous sac that follows the shape of the bony labyrinth and is filled with endolymph
- 18. The glands that produce tears, located in the upper lateral portion of the orbit
- 21. Any of the chemicals in retinal cells that are sensitive to light
- 23. Little bone; for example, the auditory bones found in the ears
- 25. The organ of hearing located in the cochlea and filled with endolymph
- 28. Any of the curved, fluid-filled tubes located in the inner ear
- 30. Part of the ear attached to the side of the head
- 32. Innermost layer of the eyeball; contains rods and cones and continues posteriorly with the optic nerve
- 33. Nearsightedness
Down
- 1. Gland that produces a waxy substance called cerumen
- 3. The refracting mechanism of the eye that is located directly behind the pupil
- 4. Thick, clear fluid that fills the membranous labyrinth of the inner ear
- 5. Ear wax
- 6. Opacity of the lens of the eye
- 7. Decrease in receptor sensitivity
- 9. Snail shell or structure of similar shape, the auditory portion of the inner ear
- 15. A curved tube extending from the auricle into the temporal bone, ending at the tympanic membrane
- 19. Receptor cell located in the retina that is stimulated by bright light
- 20. Receptors located in the retina that is responsible for night vision
- 22. Specialized nerve cell stimulated by light; for example, rods and cones of the retina
- 24. Small depression in the macula lutea where cones are most densely packed
- 26. The area in the retina where the optic nerve fibers exit and there are no rods or cones; also known as a blind spot
- 27. Farsightedness of old age
- 29. Laser-assisted in situ keratomileusis; refractory eye surgery used to vaporize and reshape underlying corneal tissue
- 31. Transparent, anterior portion of the sclera
