Across
- 2. Grassy mound on a map, or the decisive axonal cone where graded waves must clear the threshold to fire.
- 4. Node-to-node jumping conduction named after the Latin verb 'to leap'.
- 7. Toadstool-named GPCR family: odd subtypes rally IP3/DAG while even subtypes dampen cAMP.
- 8. Rest-and-digest division stretching long preganglionic cables out to ganglia buried in the target organ.
- 11. Outgoing motor nerve highway carrying orders from the central processor out to the periphery.
- 13. Aldous Huxley's fictional narcotic, or the nucleated cell body where a neuron handles its housekeeping.
- 14. Self-governing meshwork of gut neurons that runs peristalsis without waiting for brain permission.
- 15. Tree-branched neuronal listeners that gather incoming synaptic whispers and funnel them toward the soma.
- 16. Handcuff-sounding beta protein recruited after GRK tags a receptor tail, dragging it into a coated pit.
- 20. Voluntary peripheral division that sprints straight from spinal cord to skeletal muscle without a ganglion stop.
- 21. Calculated the equilibrium voltage for a single ion species, before Goldman invited the neighbours.
- 22. All-or-nothing binary clock style exemplified by an axonal action potential.
- 23. Continuous, variable-amplitude clock style exemplified by graded potentials and synaptic cleft release.
Down
- 1. Lightning-fast synaptic cleft janitor that hydrolyzes acetylcholine back into choline and acetate.
- 3. Rate-limiting cytosolic enzyme on tyrosine—or the vesicular enzyme that turns dopamine into noradrenaline.
- 5. Sensory nerve highway arriving at central command; swap the first vowel for an E and you are leaving.
- 6. Overshooting below resting potential while sluggish potassium gates take their time closing.
- 9. Greasy Schwann-built insulation jacket whose patchy autoimmune loss causes multiple sclerosis.
- 10. Dietary nutrient carried into the nerve terminal with sodium to have a cytoplasmic ChAT with acetyl-CoA.
- 12. Positive-bound voltage swing sparked when voltage-gated sodium channels fling open before potassium lags behind.
- 17. Bare uninsulated gaps along a myelinated axon where the action potential leaps to save time.
- 18. Pentameric ion channel that demands two acetylcholine molecules at once to let sodium and potassium rush in.
- 19. Gilded physiologist who added chloride and multiple cations to turn a one-ion voltage formula realistic.
- 20. Fight-or-flight division with short preganglionic stubs near the spine and long noradrenergic reach.
- 24. Final Greek character momentarily traced by a fusing synaptic vesicle as it empties into the cleft.
