The flashcards below were created by user Laurenwindas on FreezingBlue Flashcards. What would you like to do?


  1. Which area(s) of the vertebral column does the Sympathetic nervous response stimulate?
    Thoraco-Lumbar
  2. Which area(s) of the vertebral column does the Parasympathetic nervous response stimulate?
    Cranio-Sacral
  3. True or False: the Sympathetic (Fight or Flight) nervous response DILATES the eye pupils.
    True.
  4. What effect does the Parasympathetic (Rest and Digest) nervous response have on the bronchi?
    CONSTRICTS the bronchi.

    Breathing is thus more controlled.
  5. What happens to the bronchi in a sympathetic response?
    Bronchi are DILATED. This ensures high intake of oxygen in a fast-paced breathing response to stress.
  6. What is the cause of Gullain Barre Syndrome (i.e Neuritis)?
    Autoimmune
  7. Give ONE cause of Multiple Sclerosis (MS).
    Genetic (a risk factor)
  8. Give ONE main cause of Motor Neuron Disease (ALS)
    Genetic (risk factor has been found)
  9. Give one main cause of Alzheimer's Disease
    Genetic
  10. What is one possible cause of Parkinsons Disease?
    Genetics

    Bacterial Infection
  13. Give one common cause of headaches
    Caffeine withdrawal
  14. Give ONE cause of a Migraine
    Alcohol
  15. Give one cause of Epilepsy
    Head injury

    of CSF.

    Give 6 symptoms.
    • Headache
    • Neck Pain
    • Drowsiness
    • Confusion
    • Nausea
    • Vomiting
  23. What is the allopathic treatment for Hydrocephalus?
    Ventricular Catheter
  24. Give 6 Symptoms of ICP (Increased intracranial pressure)
    • Impaired Eye Movement
    • Vomiting
    • Nausea
    • Headache

    Cranial Nerve 12 (XII) - The Hypoglossal nerve seves Tongue Movement and Speech.

    It has Motor Function
  27. What function does the Vagus nerve have?
    Cranial Nerve 10 (X) - the vagus nerve aids in Swallowing, Taste and Senses from the epiglottis


    It is both MOTOR AND SENSORY
  28. What does the Accessory/Spinal nerve do?
    The 11th Nerve (XI).

    Assists in Neck and Shoulder muscle movements, Swallowing

    A cluster or group of nerve cell bodies.
  43. What is depolarisation?
    A shift from a resting membrane potential (-70mv) becoming less negative, reaching zero, and becoming more positive.
  44. What is repolarisation?
    The membrane is restored back to its resting potential of -70 mv
  45. What does the Refractory Period refer to?
    • The period of time after repolarisation in
    • which a nerve cannot generate
    • another action potential because Na+
    • and K+ are on the wrong sides of the
    • membrane!

    • During this period the Na-K pump
    • pumps Na+ out and some K+ back into
    • the cell to restore the resting potential.
  46. What is the definition of a Neurotransmitter?
    • A neurotransmitter is a chemical messenger (nerve messengers) used to create
    • synaptic transmission – transmission of a nerve impulse from one nerve to
    • another.
