  • Across which thin walls is CSF absorbed into the venous circulation?
  • Arachnoid villi
100
  • Is our CSF constant or does it change depending on our position?
  • It changes: laying supine (7-15 mmHg), sitting or standing (-10 mmHg)
100
  • Where does the inferior oblique muscle move the eye and what it it innervated by?
  • Diagonally up and out, CN III oculomotor
100
  • True or false: all of the muscle of the eye come together at the annulus of zinn except for the superior oblique.
  • False. The superior oblique, superior retus, lateral rectus, medial rectus and inferior rectus do. The inferior oblique is the outlier

200
  • The mandibular division of the trigeminal nerve innervates what muscles?
  • Four muscles of mastication-temporalis, masseter, lateral pterygoid, medial pterygoid
  • 2 suprahyoid muscles
  • Tensor tmpani (middle ear)- runs with eustation tube
  • Tensor veli palatinin(soft palate)
200
  • What is the one muscle of the tounge that is exempt from being innervated by the hypoglossal nerve?
  • Palatoglossus, this is innervated by the vagus nerve
200
  • The glossopharyngeal nerve innvervates this muscle.
  • Stylopharyngeus
200
  • Cranial nerve VI (abducens) comes out between ________ and _______ on the brainstem.
  • Labyrinthine artery and Anterior inferior cerebellar artery
300
  • Which of the cranial nerves run though the superior orbital fissure?
  • Cranial nerve III, IV, VI--- oculomotor, trochlear, abducens, as well as V1- the ophthalmic branch.
300

400
  • What cranial nerve gives general sensation and taste to the posterior 1/3 of the tounge?
  • Cranial nerve IX (glossopharyngeal)
400
  • The vagus nerve does motor to what?
  • Pharyngeal muscles (ex: stylopharyngeus -CnIX), soft palate muscles (ex: tensor veli palatini-V3), laryngeal muscles, thorasic and abdominal viscera to the left colic flexure
