Across
- 2. white fatty material that covers some nerve fibers
- 4. the emotional brain
- 8. cerebral lobe located in the back of the head
- 9. anterior portion of the cerebrum that controls voluntary skeletal activity and plays and important role in emotions, critical thinking, and ethical decision making
- 11. change in the membrane potential across the cell membrane, with the inside of the cell becoming less negative and less polarized
- 12. membranes that cover the brain and spinal cord
- 14. complex network of nerve fibers that arises within the brain stem and projects into the lower cerebrum
- 18. lower part of the brain that connects the brain to and with the spinal cord.
- 19. nerve cells that support, protect, and nourish the neurons
- 20. lobe of the cerebrum concerned primarily with somatosensory function
- 21. part of the diencephalon that regulates the pituitary gland, autonomic nervous system, water balance, appetite, temperature, and emotions
Down
- 1. lobe of the cerebrum responsible for hearing, smelling, speech, and memory
- 3. part of the brain stem that controls vital functions
- 5. largest and uppermost part of the brain, divided into two cerebral hemispheres
- 6. the interaction between two nerves where chemical transmission of the electrical signals occurs
- 7. chemical made within the axon terminal responsible for transmission of the signal across the synapse or junction
- 10. return of the membrane potential to its resting state after the nerve impulse
- 13. cushioning fluid that circulates within the subarachnoid space around the brain and spinal cord
- 15. part of the brain located under the cerebrum
- 16. sequence of changes in the membrane potential that occurs when a cell is stimulated to threshold.
- 17. nerve cell that conducts the action potential
