Across
- 6. transmitter removal that consists of enzymatic breakdown of the neurotransmitter
- 9. depolarization during an action potential is an example of a _______ feedback loop
- 10. the status that a neuron must achieve before a voltage-gated sodium channel can be deactivated
- 12. during this phase of an action potential sodium ions rush into a cell
- 14. the space between two neurons that can be electrical or chemical
- 15. this part of a neuron is where the nucleus is located
- 16. results in a more positive membrane polarization
- 17. equation that describes the equilibrium potential for a particular ion
- 19. channels that are always open, allow ions to flow freely, and are not gated
- 20. fibers that innervate skeletal muscles are part of this nervous system division
- 21. this portion of a neuron receives incoming information from distal neurons
- 23. proteins that make up gap junctions
- 25. pathway that refers stimulus information from sensory receptors to the CNS
Down
- 1. results in a more negative membrane polarization
- 2. portion of the ear consists of the oval window, cochlea, and vestibular apparatus
- 3. SSRIs like Zoloft work by blocking the re-uptake of this molecule
- 4. there are two types: absolute and relative
- 5. refers to a voltage-gated sodium channel that is closed and not capable of opening
- 7. this location on a neuron is where an action potential begins
- 8. this transmitter activates secondary messenger systems
- 11. this type of potential can vary in magnitude, is spread by passive current, and dies out over short distances
- 12. at this potential, neither sodium nor potassium ions are at their equilibrium
- 13. division of the peripheral nervous system that is associated with the fight/flight response
- 18. a component of a neuron that acts as insulation
- 22. describes when the synaptic output of one neuron is put onto many neurons
- 24. this ion enters the synaptic knob and causes neurotransmitter release via exocytosis
