5 Written questions

5 Matching questions

  1. What are the different duramatter in the brain?
  2. Explain the function of the submandibular ganglion.
  3. Explain the peripheral pathway of the CNI- Olfactory nerve.
  4. Explain the pathway of the accessory nerve (CNXI) and the branches.
  5. What is the role of the otic ganglion?
  1. a glossopharngeal (CNIX) sends preganglionic parasymphatetics to the parotid gland.
  2. b Chorda typani (facial) post ganglionic parasympathtics to the submandibular gland and the submental gland.
  3. c Falx Cerebri: divides the cerebral lobes
    Tentorium Cerebelli: Divides the cerebrum from the pons- except for the tentorial notch w/ allows communication
  4. d Has a cranial and spinal root. Spinal root comes to join the cranial root in the skull and then they leave the skull. Cranial root becomes apart of the vagus nerve and the spinal root innervates the traps and sternocleidomastoid. PAIN GOES TO CERVICAL NOT CRANIAL ROOTS.
  5. e Receptors in the nose travel to the cell bodies in the olfactory bulb that sits on the cribiform plate of the ethmoid bone. Here axons continue to the brain.

5 Multiple choice questions

  1. Against Medial wall sits the carotid siphon and the sphenoid fossa.
    CN III, IV, VI corse through to exit out the superior orbital fissure (between the wings of the sphenoid).
    Trigeminal splits to exit (opthalmic out the superior orbital fissure, maxillary out the foramen rotunda, and mandibular out the foramen ovale).
  2. On the side of the foramen magnum
  3. Extorsion: Inferior oblique and rectus
    Intorsion: Superior oblique and rectus
  4. Optic Nerve: eye to chiasm
    Optic Tract: chiasm to brain
    Nasal portion nerves cross in chiasm while the lateral portions do not. Thus left field processed by right side of the brain and vice-versa.
  5. Sensory/motor
    Opthalmic- sensation to forehead and cornea
    Maxillary- sensation to maxillary and upper teeth
    Mandibular- sensation to madible and works chewing muscles

5 True/False questions

  1. Explain how taste occurs.Where the jugular vein leaves as well as CN 9, 10, 11. (Vagus, glosspharngeal, accessory).

          

  2. Explain the pathway of the facial nerve (CNVII)Supplies muscle of the tongue. Especially the genioglossus muscle going from the tip of the mandible to the posterior portion of the tongue.

          

  3. What muscles are responsible for opening and closing the eye?Extorsion: Inferior oblique and rectus
    Intorsion: Superior oblique and rectus

          

  4. Explain the peripheral pathway of the CNVII- oculomotor nerve.Has voluntary movement and parasymphthetic constriction of the eye. As such- synapse in the ciliary ganglion behind the eye and the to the brain. REMEMBER THIS SYNAPSE before going to the brain.

          

  5. What muscles responsible for looking up and down?Up- Superior oblique and inferior rectus
    Down- Inferior oblique and superior rectus
