Across
- 4. cells that nourish or insulate neurons
- 7. part of brain that develops into 3 regions: epithalamus, thalamus & hypothalamus
- 10. in the frontal lobe is active when speech is formed
- 12. in the temporal lobe is active when speech is heard
- 15. neurons that transmit information away from the CNS
- 16. The differences in hemisphere function
- 19. cluster of nerve cells in the CNS
- 20. an increase in magnitude of the membrane potential
- 21. Regulates homeostasis & basic survival behaviors
- 23. consists of neuron cell bodies, dendrites, and unmyelinated axons
- 24. Includes pineal gland and generates CSF from blood
- 25. clustering of sensory organs at the front end of the body
- 27. coordinates brain centers & has 3 parts: midbrain, pons, medulla oblongata
- 28. bundles that consist of the axons of multiple nerve cells
- 29. part of neuron that transmits signals to other cells at synapses
Down
- 1. receives & integrates sensory information
- 2. cluster of neurons in the PNS
- 3. part of neuron that receives signals from other neurons
- 5. regulates breathing centers in medulla
- 6. a reduction in the magnitude of the membrane potential
- 8. cone shaped base of axon
- 9. centers to control several functions
- 11. junction between an axon and another cell
- 12. consists of bundles of myelinated axons
- 13. structure most important to the storage of emotion; a mass of nuclei near the base of the cerebrum
- 14. neurons that transmit information to the CNS
- 17. a common neurotransmitter in vertebrates and invertebrates
- 18. relatively short chains of amino acid; function as neurotransmitters
- 22. main input center for sensory info also main output center for motor info
- 25. part of brain that is involved in learning & remembering motor skills
- 26. nerve cells that transfer information within the body
