- 12. lobe of brain receiving messages from cranial nerve II
- 13. tough, white outer layer of eye
- 14. charge inside axon becomes positive as Na+ goes in
- 18. pigmented part of eye that controls pupil
- 20. nervous system associated with voluntary movement
- 21. part of neuron that stores neurotransmitters
- 23. more Na+ outside, K+ inside axon
- 24. found in middle ear, used to amplify sound waves
- 25. found on retina, has highest concentration of cones
- 26. lobe associated with problem solving, speech, decision making
- 27. part of inner ear lined with hair cells used for hearing

Down
- 1. allows you to move eye clockwise
- 2. photoreceptor of eye found as red, green or blue
- 4. vascular layer of eye that has melanin
- 5. function of both the hippocampus and temporal lobe
- 8. part of limbic system associated with fear, anger, anxiety
- 9. neuroglial cell that makes myelin for CNS
- 10. extrinsic eye muscle used to look downward
- 11. membrane covering brain; made up of dura, arachnoid and pia mater
- 15. used to equalize air/fluid pressure in ear
- 16. part of eye with no rods or cones; where optic nerve passes into eye
- 17. part of inner ear that deals with balance
- 19. opening of eye controlled by iris that allows light to hit the lens
- 22. myelin found between right and left hemispheres connecting the sides
- 29. neuroglial cell that cleans up debris in CNS
