Anatomy
Across
- 3. The nerve that transmits impulses to the brain from the nose.
- 5. The clear, outermost layer of the eye that light passes through.
- 7. Chemical messengers produced by endocrine glands that are released into the blood.
- 8. The part of the brain that "thinks".
- 9. A neuron that transmits impulses from one neuron to another.
- 10. The fatty covering of axons that allows the signals to transmit speedily.
- 12. neurons that make one move or contract muscles
- 13. The sensory and motor neurons in the body (arms, legs, and trunk)
- 14. A neuron that causes one to feel, taste, see, smell, and hear.
- 16. The fluid-filled series of tubes in the inner ear that help with hearing (as opposed to balance).
Down
- 1. The nerve that carries visual signals from the retina to the occipital lobe in the brain.
- 2. These carry electrical impulses and information toward or into the neuron.
- 4. a part of the eye that changes shape to focus near and far objects
- 6. The extension of the neuron that carries information away from the neuron.
- 8. The neurons in the brain and spinal cord.
- 9. The muscle that controls the size (or the opening and closing) of the pupil.
- 11. A thin membrane (that is actually a muscle) between the auditory canal and the middle ear bones.
- 15. Light cells responsible for processing color.
