- Explain branching of the internal carotid artery.
- Explain the specific branches of the mandibular nerve.
- a On the side of the foramen magnum
- b Anterior 2/3 is the facial nerve (CNVII) through lingual nerve.
Posterior 1/3 is the glossopharngeal nerve (CN IX)
- c Two layers:
1. meningeal layer (to tissue)
2. periosteal layer (to the skull)
The area in between the two is sinus where vein can travel.
- d Has the lingual (sensation to tonuge) and the mental (sensation to mandible) components.
- e Splits into:
1. opthalmic (eye supply)
2. Middle cerebral (lateral side of brain)
3. Anterior cerebral (anterior medial portion of the brain)
Anastomoses with the vertebral artery.

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
Explain the peripheral pathway of the CNI- Olfactory 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.
What are the parasympathetic ganglions in the face? → Falx Cerebri: divides the cerebral lobes
Tentorium Cerebelli: Divides the cerebrum from the pons- except for the tentorial notch w/ allows communication
Explain the pathway of the facial nerve (CNVII) → Enters the internal acoustic meatus to hit the geniculate ganglion. Main branch goes out the stylomastoid foramen to supply face muscles, while it sends a chorda tympani branch to join lingual to go to submandibular/mental glands and carry taste. A smaller branch leaves geniculate ganglion called the greater petrosal nerve to hit the pterygopalatine ganglion and supply other glands.
Explain where the trigeminal nerve exits externally. → CN 7 and CN 8 (Facial and vestibulacoclear) leave the skull.
What are the components of the gag reflex? → Sensory- glossopharngeal
