5 Written questions

5 Matching questions

  1. interneurons
  2. Sensation
  3. microglia
  4. if transmission is _______ the NT-receptor reaction will depolarize
  5. signal sent to synaptic bulb will release ____ to diffuse across _____
  1. a NT; synaptic cleft
  2. b excitatory
  3. c specialized immune cells that act as macrophages (disease eaters) of CNS
  4. d in CNS, form connecting link between afferent & efferent
  5. e monitors changes/events occurring in & outside the body (stimuli); cells that respond=receptors

5 Multiple choice questions

  1. axon terminal; site of transduction (conversion of an electrical signal into chemical signal)
  2. motor output (effectors=response); the activation of muscles or glands (typically via release of NTs)
  3. myelinated, axon w/ largest diameter
  4. occurs in unmyelinated axons; wave of depolarization & repolarization travels from one membrane patch to the next--like dominoes falling
  5. 31; carry info to and from spinal cord

5 True/False questions

  1. Functions of the Nervous Systemvoluntary; from CNS to muscles


  2. Schwann cellssurround clusters of neuronal cell bodies in PNS-unknown function


  3. PNSbrain & spinal cord; central of integration and control


  4. action potentialinvolved in formation of blood brain barrier, nutrient transfer, clearance of NTs


  5. excitabilityK+ channels open, hyper-polarizes membrane and it's more difficult for AP to occur
