: True/False - Skull lecture 2013
: These questions were not submitted by the lecturer
: 1. The pterion is so named in reference to a prehistoric bird having a greater wing. Perhaps a pterodactyl.
true!!!!! caw caw
: 2. The parietal foramina transmit emissary veins.
true- the parietal foramina transmit veins that drain the scalp and drain into the superior dural sinus.
: 3. The parietal foramina provide communication between the region of the scalp and the cranium.
true- as stated above through veins
: 4. The condylar canal transmits the hypoglossal nerve and the hypoglossal canal transmits the condylar emissary vein.
false- the hypoglossal canal (anterior to the condyle that articulates with C1) transmits the hypoglossal nerve. the condylar canal (posterior to the condyle that articulates with C1) transmits the occipital vein (?)
: 5. The jugular canal transmits the common carotid artery into the skull.
false- the jugular canal transmits the internal jugular vein into the skull
: 6. The petrotympanic fissure transmits the tympanic branch of the glossopharyngeal nerve.
false- it transmits the tympanic branch of the maxillary nerve
: 7. The continuation of the facial nerve into the parotid region is by way of the stylomastoid foramen.
true- the facial nerve exits the skull at the stylomastoid foramen to travel through the parotid gland and then split to innervate muscles of the face
: 8. The stylomastoid foramen provides communication between the facial canal of the occipital bone and the infratemporal fossa.
false- should be facial canal of the temporal bone
: 9. The epicranial aponeurosis (galea) is the intertendon of the occipitofrontalis muscle.
: 10. The dura mater of the cranial cavity, unlike in the spinal canal, is adhered to the endosteum. Thus, there is not an epidural space.
