Across
- 5. THE SMALL GAPS OF A FEW MICROMETERS THAT SEPARATE ADJACENT INTERNODES
- 6. THESE NEURONS MONITOR THE OUTSIDE WORLD AND OUR POSITION WITHIN IT
- 8. A NEURON WITH MANY DENDRITES AND A SINGLE AXON
- 10. THE CHANGE IN ELECTRICAL POTENTIAL ASSOCIATED WITH THE PASSAGE OF AN IMPULSE ALONG THE MEMBRANE OF A MUSCLE CELL OR NERVE CELL
- 12. NEURONS THAT DISTRIBUTE SENSORY INFORMATION AND COORDINATE MOTOR ACTIVITY
- 13. AREAS IN THE CNS CONTAINING NEURON CELL BODIES, DENDRITES, AND UNMYELINATED AXONS THAT HAVE A DUSKY GRAY COLOR
- 14. THE MEMBRANE POTENTIAL OF A NORMAL CELL UNDER HOMEOSTATIC CONDITIONS
- 15. CHANGES IN MEMBRANE POTENTIAL THAT VERY IN SIZE, AS OPPOSED TO BEING ALL-OR-NONE
- 16. THESE NEURONS INNERVATE SKELETAL MUSCLES
- 19. AN ION CHANNEL THAT OPENS AND CLOSES IN RESPONSE TO CHANGES IN ELECTRICAL POTENTIAL ACROSS THE CELL MEMBRANE IN WHICH THE CHANNEL IS SITUATED
Down
- 1. FLUID BATHING THE INTERNAL AND EXTERNAL SURFACES OF THE CNS
- 2. MONITOR INTERNAL CONDITIONS AND THE STATUS OF OTHER ORGAN SYSTEMS
- 3. AN INTEGRAL MEMBRANE PROTEIN WHICH IS AN ION CHANNEL WITH AN EXCITABLE CELL'S OUTER CELL MEMBRANE, WHICH OPENS AND CLOSES IN RESPONSE TO A STIMULUS WHICH IS THE ARRIVAL AND BINDING OF A CHEMICAL MESSENGER, SUCH AS A NEUROTRANSMITTER
- 4. THE FAIRLY LARGE AREAS OF THE AXON THAT ARE WRAPPED IN MYELIN
- 7. THESE NEURONS INNERVATE ALL PERIPHERAL EFFECTORS OTHER THAN SKELETAL MUSCLES SUCH AS SMOOTH MUSCLE, CARDIAC MUSCLE, GLANDS, AND ADIPOSE TISSUE
- 8. CHANNELS THAT OPEN AND CLOSE IN RESPONSE TO PHYSICAL DISTORTION OF THE MEMBRANE SURFACE
- 9. A SENSORY NEURON WHOSE CELL BODY IS IN A DORSAL ROOT GANGLION OR A SENSORY GANGLION OF A CRANIAL NERVE
- 11. REGIONS IN THE CNS THAT ARE DOMINATED BY MYELINATED AXONS
- 17. AN INSULATING SHEATH AROUND AN AXON
- 18. THESE CELLS ASSIST IN PRODUCING, MONITORING, AND CIRCULATING CSF
