  18. DIVISIONS OF THE NERVOUS SYSTEM $100 Name the 2 main divisions of the Nervous System. Central NS & Peripheral NS

  19. DIVISIONS OF THE NERVOUS SYSTEM $200 The Central Nervous System is comprised of the _______ and ______. Brain and spinal cord

  20. DIVISIONS OF THE NERVOUS SYSTEM $300 The efferent peripheral nervous system is divided into what 2 sub- systems? Autonomic and Somatic

  21. DIVISIONS OF THE NERVOUS SYSTEM $400 The autonomic division of the PNS is divided into what 2 subdivisions? Sypathetic and parasympathetic

  22. DIVISIONS OF THE NERVOUS SYSTEM $500 You find yourself in a frightful situation. In terms of the sympathetic & parasympathetic nervous system, explain 3 body functions under smooth muscle, cardiac muscle and glands that are altered by EACH system. DAILY DOUBLE . Gland release norepinephrine releases adrenaline also called epinephrine

  23. KNOW YOUR NEUROTRANSMITTERS $100Choose from list! This NT is found in both the CNS and the PNS. It is involved in the control of skeletal muscle contractions. It stimulates skeletal muscle contraction at the neuromuscular junction. acetylcholine

  24. KNOW YOUR NEUROTRANSMITTERS $200Choose from list! This NT has its greatest effect in the CNS. It creates a sense of feeling good. Many “entertainment” drugs work by increasing this NT. Lack of it causes Parkinson’s disease. dopamine

  25. KNOW YOUR NEUROTRANSMITTERS $300Choose from list! This NT is released by the CNS and promotes alertness. Histamine

  26. FJ CH 10 VOCABULARY ACTION POTENTIAL SYNAPSES NERVOUS SYSTEM HISTOLOGY POTPOURRI 200 200 200 200 200 400 400 400 400 400 600 600 600 600 600 800 800 800 800 800 1000 1000 1000 1000 1000 DOUBLE JEOPARDY!

  27. ACTION POTENTIAL $200 A normal resting neuron has a _______ on the outside. Negative Neutral Positive positive

  28. KNOW YOUR NEUROTRANSMITTERS $400Choose from list! This NT is only found in the CNS and is an inhibitory NT. It leads to sleepiness. The drug LSD blocks this action. On the other hand, certain reuptake drugs can enhance this NT. serotonin

  29. KNOW YOUR NEUROTRANSMITTERS $500Choose from list! This neuropeptide _______ is excitatory in the CNS leading to pain perception. However, in the PNS this neuropeptide ______ reduces pain by inhibiting the previously mentioned NT. Substance P Endorphins (enkephalins)

  30. ACTION POTENTIAL $400 The sodium potassium pump moves # of these ions to the outside of the cell and moves # of these ions to the inside of the cell. Fill in the specific number and ion name. 3 Na out 2 K in

  31. ACTION POTENTIAL $600 Name the 3 main ions involved in an action potential. Calcium, sodium, potassium

  32. ACTION POTENTIAL $800 What is the SPECIFIC role of calcium in an action potential? It causes the neurotransmitter vesicles to move to the cell edge and undergo exocytosis.

  33. ACTION POTENTIAL $1000 Discuss the relationship between these 3 parts of an ACTION POTENTIAL. Ligand Acetylcholine Sodium Voltage gate DAILY DOUBLE Acetylcholine acts as a ligand on the sodium voltage gate. The ligand causes the gate to open and allows Na to flow into the cell beginning the action potential.

  34. VOCABULARY CH. 10 $200 biological messengers produced by neurons. neurotransmitter

  35. VOCABULARY $400 the initial portion of an axon closest to the cell body where the action potential is started Axon hillock

  36. VOCABULARY $600 White matter versus gray matter Myelinated versus unmyelinated

  37. VOCABULARY $800 . _____________ potential is a type of membrane change in which the receiving cell membrane is depolarized. excitatory postsynaptic

  38. VOCABULARY $1000 DAILY DOUBLE Explain All-or-None Response . A nerve impulse is an all-or-nothing response, meaning if a neuron responds at all to a nerve impulse, it responds completely.
