Across
- 3. covers the axon of some neurons and helps speed neural impulses (MS)
- 6. Area of the brain responsible for all voluntary activities of the body (C)
- 9. plasma-like clear fluid circulating in and around the brain and spinal cord (CSF)
- 11. chemical messengers that cross the synaptic gaps between neurons (N)
- 15. A region of the cerebral cortex that processes visual information (OL)
- 16. the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron (S)
- 17. a nerve cell; the basic building block of the nervous system (N)
- 18. cells that support and protect neurons (N)
Down
- 1. Brain and spinal cord tissue that appears gray with the naked eye; consists mainly of neuronal cell bodies (nuclei) and lacks myelinated axons (GM)
- 2. information transmitted in the form of electrical and chemical changes (I)
- 4. three protective membranes that surround the brain and spinal cord (MC)
- 5. A region of the cerebral cortex associated with reasoning, planning, parts of speech, movement, emotions, and problem solving (FL)
- 7. A region of the cerebral cortex whose functions include processing information about touch (PL)
- 8. A region of the cerebral cortex responsible for hearing and language (TL)
- 10. Branchlike parts of a neuron that are specialized to receive information (D)
- 12. Extension that carries impulses away from the cell body (A)
- 13. Nerves that run up and down the length of the back and transmit most messages between the body and brain (SC)
- 14. Whitish nervous tissue of the CNS consisting of neurons and their myelin sheaths (WM)
