2. DAILY DOUBLE Back

3. DAILY DOUBLE Back

4. This is the chemical that goes inside of a neuron that allows for action potentials to be sent Back sodium

5. This is what takes place within the neuron when enough sodium comes in at the right time Back Action potential

6. When the membrane allows for more positive charges to enter and for the cell to reach the threshold, then it is known as this Back depolarization

7. What do the neurotransmitters bind to? Back Postsynaptic receptors

8. These chemicals travel from the presynaptic to the postsynaptic membrane in order to trigger the movement of an action potential Back neurotransmitters

9. This hormone can bind to specific receptors that have different responses. Back Estrogen

10. The conversion of extracellular signals into a response that is triggered inside of a cell is known as this Back Signal transduction

11. What type of transduction amplifies the original signal? Back Phosphorylation (kinases)

12. This causes glucose to be diverted away from the blood Back insulin

13. This is the area of the brain that is responsible for the production of many hormones throughout your body Back hypothalamus

14. This is the branch of the nervous system that is responsible for the fight or flight reaction Back sympathetic

15. These are the types of neurons that are associated with peripheral nervous system Back Sensory, moto,r, autonomomic

16. This nervous system contains your brain and spinal cord Back central

17. This is the nervous system that includes digestion as well as the sympathetic and parasympathetic nervous systems Back autonomic

18. Pupil constriction as well as normal digestive functioning is triggered by this system Back parasympathetic

19. This causes signals to be only sent in one directions. Back Refractory period

20. These are the areas where neurotransmitters pass through, while these are the areas where they bind Back Presynaptic, postsynaptic membrane

21. These are the depolarized regions of the axon Back Node of Ranvier

22. The movement of sodium and potassium is carried out by these Back Sodium-potassium pump, ion channels

23. These are the areas of the neuron that receive signals from other neurons Back dendrites

24. These are the two organs that are associated with the regulation of glucose Back Pancreas and liver

25. This occurs when a response reduces the initial stimulus Back Negative feedback

26. This is the chemical that gets you prepared for a fight or flight situation Back epinephrine

27. These are molecules that are secreted into extracellular fluid and circulates throughout the blood Back hormones

28. These signals can trigger cell differentiation and cell proliferation Back Growth factors

29. potential that’s further away from the threshold Back hyperpolarization

30. self signalling Back autocrine

31. massive change in membrane voltage Back Action potential

32. Water soluble polypeptide hormone Back insulin

33. hormone that releases glucose from tissues Back glucagon

34. These are the areas that go away from the cell body in Ned the Neuron Back axons

35. The purple that you see in Ned’s cell is known as this Back myelin

36. Because the action potentials between Ned and his neighbor go from node to node, this is the name for the type of conduction that takes place Back Saltatory conduction

37. These travel inside of Ned in order to carry neurotransmitters to other neurons Back Synaptic vesicles

38. This is the gap between Ned and the neuron that he is connected to Back Synaptic cleft
