Across
- 2. brain tissue is able to take on new functions
- 4. connects the two brain hemispheres and carries messages between them.
- 5. Located in temporal lobe, helps control receptive language
- 6. States that if a neuron fires, it always fires at the same intensity; all action potentials are the same strength
- 9. Division of the peripheral nervous system that controls the body's skeletal muscles
- 10. lying at top of head toward the rear; includes somatosensory cortex and general association area
- 11. Tiny, fluid filled gap between the axon terminal of one neuron and the dendrite of another
- 12. "recharging phase" when a neuron, after firing, cannot generate another action potential
- 13. State of a neuron when it is at rest and capable of generating an action potential
- 15. A chemical messenger that travels across the synapse from one neuron to the next and influences whether a neuron will generate an action potential
- 17. Division of the peripheral nervous system that controls the body's skeletal muscles
- 18. Brain's outer wrinkly surface. Bodies ultimate control and information processing center
- 20. lying at back of head; includes visual processing area
- 21. Nerves that carry information to the muscles and glands from the CNS
- 22. Cell body of a neuron, which contains the nucleus and other parts that keep the cell healthy.
- 23. lies just behind the forehead; includes motor cortex; involved in making plans and judgment
- 24. Extension of a neuron through which neural impulses are sent
Down
- 1. lying above the ears; auditory areas
- 3. Bushy branching extensions of a neuron that receive messages and conduct impulses toward the cell body
- 4. Brain and Spinal Cord
- 7. A nerve cell; basic building block of nervous system
- 8. sensory and motor nerves that connect the central nervous system to the rest of the body
- 14. Nerves that carry information from the sense receptors to the Central Nervous System (CNS)
- 16. A neural impulse; a brief electrical charge that travels down the axon of a neuron
- 17. Endpoint of a neuron, where neurotransmitters are stored
- 19. Frontal lobe, usually left hemisphere, directs muscle movement involved in speech
