Across
- 7. the lower part of the brainstem, comprising the cerebellum, pons, and medulla oblongata.
- 9. chemical messengers that your body can't function without.
- 13. a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
- 16. the nerve fibers responsible for bringing sensory information from the outside world into the brain.
- 17. a network of nerves that helps your body activate its “fight-or-flight” response.
- 20. They are most commonly associated with processing auditory information and with the encoding of memory
Down
- 1. a network of nerves that relaxes your body after periods of stress or danger.
- 2. a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal.
- 3. the nervous system outside the brain and spinal cord.
- 4. a component of the peripheral nervous system associated with the voluntary control of the body movements via the use of skeletal muscles.
- 5. the rearmost lobe in each cerebral hemisphere of the brain
- 6. the outer layer of the cerebrum (the cerebral cortex ), composed of folded gray matter and playing an important role in consciousness.
- 8. a broad band of nerve fibers joining the two hemispheres of the brain.
- 10. the anterior part of the brain, including the cerebral hemispheres, the thalamus, and the hypothalamus.
- 11. the adaptability of an organism to changes in its environment or differences between its various habitats.
- 12. the nerve fibers responsible for carrying signals from the brain to the peripheral nervous system in order to initiate an action.
- 14. the complex of nerve tissues that controls the activities of the body. In vertebrates it comprises the brain and spinal cord.
- 15. our behavior and emotional control center and home to our personality
- 18. either of the paired lobes of the brain at the top of the head, including areas concerned with the reception and correlation of sensory information.
- 19. a specialized cell transmitting nerve impulses; a nerve cell.
