Across
- 2. base of the cerebrum; relays information between the brain and the spinal cord
- 5. covers long axons to insulate the elecrical signal
- 6. Lobe that is primarily involved in sensory perception; allows you to process senses such as touch, pain, temperature, and pressure.
- 8. excitable cells that respond to stimuli by conducting impulses to transmit signals
- 9. unmyelinated gaps in the myelin sheath that aid in increasing the velocity of nerve signal conduction
- 13. supportive cells that provide nutrition, insulation, and help with signal transmission
- 16. bundles of axons that extend from the brain and spinal cord to the rest of the body.
- 18. the ultimate control center of the body overseeing all communication among the organ systems
- 20. Lobe involved in taste; planning and problem solving
- 21. Directs sensory signals to the proper region of the cerebrum to process those signals
- 22. control center for heart rate and respiration
Down
- 1. Lobe that allows you to process auditory information and remember short-term and long-term memories
- 3. the folded surface of the cerebrum
- 4. the main receptor of signals; input region of a neuron
- 7. the end of the axon that releases neurotransmitters at a synapse when a nerve impulse is received; the secretory region of a neuron
- 10. Lobe where visual information from the eyes is processed.
- 11. "bridge" of the brainstem; sends information between your cerebrum and cerebellum
- 12. "the little brain"
- 14. Helps your body maintain homeostasis
- 15. generates and transmits nerve impulses; the conducting region; also known as a nerve fiber
- 17. the largest part of the brain that is divided into 4 lobes
- 19. The uppermost part of the brain stem that allows the body to react reflexively to visual and auditory information
