  1. How many pairs of cranial nerves are there?
    12 pairs
  2. Which cranial nerves are ONLY SENSORY?
    • I
    • II
    • VIII
  3. Which cranial nerves innervate skeletal muscles? (mainly MOTOR)
    • III
    • IV
    • VI
    • XI
    • XII
  4. Where are cell bodies of sensory neurons located?
    in the basal ganglia OUTSIDE the brain
  5. Where are the Cell bodies of MOTOR NEURONS located?
    in the nuclei within the brain
  6. This nerve ends in the Temporal Lobe of the Cerebral Cortex and is Cranial N I
    Olfactory N
  7. This term describes the lact of olfaction or ABSENCE of ABILITY to SMELL
  8. A decreased ability to smell is called
  9. An INCREASED ability to smell is called
  10. "Specific Ansomia"
  11. Fake perceptions of smell often as a result of damage to the Temporal Lobe is called
    Olfactory Hallucinations
  12. This is known as the lessening or loss of olfactroy sense (due to aging)
  13. This nerve controls movements of the eyeball and upper eyelid
    Oculomotor III N
  14. These two cranial nerves convey nerve impulses for proprioception
    • Oculomotor III N
    • Trochlear IV N
  15. Smallest of the 12 cranial Nerves
    Trochlear IV Nerve
  16. The LARGEST of the cranial nerves
    Trigeminal V Nerve
  17. What are the 3 branches of the Trigeminal V Nerve
    • Opthalmic (smallest)
    • Maxillary (medium)
    • Manidibular (largest)
  18. This cranial nerve controls chewing movements
    Trigeminal V
  19. This cranial nerve causes lateral rotation of the eyeball
    Abducens VI Nerve
  20. Sensory portions fot ehis nerve contains axons from proprioceptors in muscles of the face and scalp
    Facial VII Nerve
  21. This nerve has two branches and was formerly knowsn as the Acoustic and Auditory Nerve
    The Vestibulocochlear VII Nerve
  22. The branches of the Vetibulocochlear VIII Nerve are:
    • Vestibular - carries impulses for equilibrium
    • Cochlear - carries impulses for hearing

    end in the MEDULLA OBLONGATA
  23. the sesnosry axons of this nerve arise from tastebuds and somatoic sensory receptors on posterior 1/3rd of the tongue
    Glossopharyngeal XI Nerve
  24. This nerve stimulates the parotid gland to secrete saliva
  25. This Nerve is distributed from head and neck into thorax and abdomen
    The Vagus X Nerve
  26. Axons of Autonomic motor neurons of the Vagus Nerve originated and end in which locations?
    • Originate in nuclei of the Medualla
    • End in the Lungs and Heart
  27. Which cranial nerve differs from all others and HOW?
    • The Accessory XI N
    • originates from BOTH brain stem and spinal cord
  28. Motor Neurons for this cranial nerve conduct nerve impulses for SPEECH and SWALLOWING
    Hypoglossal XII Nerve
  29. What is the order of all 12 Cranial Nerves?
    Olfactory, Optic, Oculomotor, Trochlear, Trigeminal, Abducens, Facial, Vestibulocochlear, Glossopharyngeal, Vagus, Accessory, Hypoglossal
  30. This secretes substances that remain in the body
    Endocine Gland (travels through the blood)
  31. This secretes substances outside the body
    Exocrin (sweat, gastric juices)
  32. This is a chemical messenger (mediator) that carries a signal from one cell (or group of cells) to another
  33. These pass into the blood and acto on distant cells
    • Circulating Hormones
    • *have longer lasting effects until inactivated by the liver and excreted by the kidney
  34. These are restricted to interstitial fluid and affect nearby cells
    • Paracrine Secretions
    • * local hormones- inactivated quickly
  35. These affect only the secreting cell itself
    • Autocrine Secretions
    • * local hormones - inactiviated quickly
  36. Three types of lipid soluble hormones are:
    • steroid hormones
    • thyroid hormones
    • nitric oxide
  37. Thyroid hormones produce
    • Thyroxin (T4) and Triiodothronine (T3)
    • made by attaching iodine to Tyrosine
  38. These are the 3 Water Soluble Hormones
    • Amine Hormones
    • Peptide/Protien Hormones
    • Eicosanoid Hormones
