Foramen spinosum transmits the middle meningeal artery and nervus spinosus. Injury to the middle meningeal artery can cause an extradural hematoma.
Foramen spinosum transmits:
1). Middle meningeal artery + nervus spinosus (V3 meningeal branch)
2). V2
3). ICA
4). V3
The hyoid bone is generally located at approximately the level of the third cervical vertebra and appears as a bilateral radiopacity below the mandible.
Hyoid bone on panoramic appears at level of:
1) C3 vertebra
2) C1
3) Mandible
4) Not visible
The thyroid gland begins as a median endodermal diverticulum at the foramen cecum of the tongue and descends through the thyroglossal duct.
The thyroid gland originates at:
1) Foramen ovale
2) Jugular foramen
3) Foramen cecum
4) Hypoglossal canal
The common carotid artery bifurcates into the internal and external carotid arteries within the carotid triangle, usually at the level of the upper border of the thyroid cartilage.
28. Which artery bifurcates within the carotid triangle?
1) External carotid artery
2) Common carotid artery
3) Vertebral artery
4) Subclavian artery
Parasympathetic fibers reach the otic ganglion through the lesser petrosal nerve and then travel via the auriculotemporal nerve to provide secretomotor supply to the parotid gland.
Which nerve provides secretomotor to parotid gland?
1) Auriculotemporal nerve (postganglionic from otic ganglion)
2) Chorda tympani
3) Lingual nerve
4) Buccal nerve
The facial artery can be palpated where it crosses the inferior border of the mandible at the anterior border of the masseter muscle.
Which artery is palpated at anterior border of masseter?
1) Facial artery
2) Superficial temporal
3) Maxillary
4) Lingual
The sphenomandibular ligament extends from the spine of the sphenoid to the lingula of the mandible and is an important landmark during an inferior alveolar nerve block.
The sphenomandibular ligament attaches inferiorly to:
1) Coronoid process
2) Lingula of mandible
3) Angle of mandible
4) Neck of condyle
The midpalatal or median palatine suture runs anteroposteriorly in the midline of the hard palate and appears as a radiolucent line on a maxillary occlusal radiograph.
Which suture is seen as radiolucent line between two maxillae in maxillary occlusal?
1) Midpalatal suture
2) Transpalatine suture
3) Zygomaticomaxillary suture
4) Nasopalatine suture
CN VII is associated with the pterygopalatine and submandibular ganglia. CN IX is associated with the otic ganglion and CN III with the ciliary ganglion.
Parasympathetic ganglia associated with CN VII are:
1). Ciliary and Otic
2). Pterygopalatine and Submandibular
3). Otic and Ciliary
4). Ciliary only
