Across
- 2. nervous system- a network of nerves branching out from the spinal cord that conduct information from the bodily organs to the central nervous system and take information back to the organs
- 7. nervous system- stimulates a variety of physical responses to prepare the body for the stressful situation—this is the fight-or-flight response.
- 10. nervous system- the part of the nervous system that consists of the brain and spinal cord
- 11. callosum- carries messages back and forth between the two hemispheres to jointly control human functions.
- 13. the largest part of the brain that covers the brain’s central core, consisting of left and right hemispheres, which are connected by a wide band of fibers, the corpus callosum
- 15. the chemicals released by neurons, which determine the rate at which other neurons fire
- 18. neurons- relay messages from the sense organs (including eye, ear, nose, and skin) to the brain
- 20. cortex- the gray mass surrounding the subcortex, which is the information-processing center that controls the higher brain functions, such as reading and problem solving
Down
- 1. a part of the brain located at the rear base of the skull that is involved in the basic processes of life such as sleeping, waking, coordinating body movements, and regulating vital reflexes
- 3. neurons- send signals from the brain to the glands and muscles.
- 4. nervous system- conserve energy and to enhance the body’s ability to recover from strenuous activity
- 5. lobe- concerned with hearing, memory, emotion, and speaking
- 6. lobe- is where the visual signals are processed
- 8. lobe- concerned with information from the senses from all over the body
- 9. the ability of neural networks in the brain to change through growth and reorganization.
- 12. nervous system- the portion of the peripheral nervous system that controls internal biological functions such as heart rate, breathing, and blood pressure
- 14. the long, thin cells that constitute the structural and functional unit of nerve tissue along which messages travel to and from the brain
- 16. nervous system- the division of the peripheral nervous system that controls voluntary movement of skeletal muscles
- 17. the gap that exists between the axon terminals of the sending neuron and the dendrites of the receiving neuron
- 19. lobe- concerned with organization, planning, and creative thinking
