Which bone forms the lower jaw?
Zygomatic
Temporal
Maxilla
Mandible
The mandible is the only movable bone of the skull forming the lower jaw. It articulates with the temporal bones at the temporomandibular joints.
Which muscle is the primary elevator of the mandible during mastication?
Masseter
Platysma
Buccinator
Orbicularis oris
The masseter muscle originates on the zygomatic arch and inserts on the mandible to elevate the jaw. It is one of the strongest muscles of mastication.
What is the anatomical term for the cheek region?
Buccal
Labial
Mental
Lingual
The buccal region refers to the cheek area. The term labial refers to the lips, lingual to the tongue side, and mental to the chin.
Through which foramen does the infraorbital nerve exit the maxilla?
Infraorbital foramen
Supraorbital foramen
Mandibular foramen
Mental foramen
The infraorbital nerve, a branch of V2, exits the maxilla through the infraorbital foramen to supply the midface. The infraorbital foramen is located below the orbit on the maxilla.
Which bone is commonly referred to as the cheekbone?
Sphenoid bone
Vomer
Zygomatic bone
Lacrimal bone
The zygomatic bone forms the prominence of the cheek and part of the lateral orbit. It articulates with the maxilla, sphenoid, frontal, and temporal bones.
The floor of the temporal fossa is formed by which bones?
Sphenoid, occipital, and ethmoid
Parietal, frontal, and occipital
Temporal, occipital, and parietal
Frontal, parietal, temporal, and sphenoid
The temporal fossa floor comprises the frontal, parietal, temporal, and greater wing of the sphenoid bones. These bones provide attachment for the temporalis muscle.
Which muscle assists in depressing the mandible and protruding the jaw?
Masseter
Temporalis
Lateral pterygoid
Medial pterygoid
The lateral pterygoid muscle contracts to depress and protrude the mandible at the TMJ. Its superior head also aids in stabilizing the joint during mastication.
Into which vein does the facial vein primarily drain?
Subclavian vein
Internal jugular vein
External jugular vein
Superior vena cava
The facial vein drains blood from the superficial structures of the face into the internal jugular vein. It descends obliquely across the face and neck.
What nerve carries general sensory information from the anterior two-thirds of the tongue?
Glossopharyngeal nerve (IX)
Chorda tympani nerve
Lingual nerve (branch of V3)
Hypoglossal nerve (XII)
The lingual nerve, a branch of the mandibular division of V, carries general sensory innervation from the anterior two-thirds of the tongue. The chorda tympani carries taste fibers.
A mandibular torus is an example of what type of anatomical variant?
Sulcus
Cyst
Fissure
Exostosis
A mandibular torus is a benign bony exostosis on the inner surface of the mandible. Exostoses are localized bony growths projecting from cortical bone.
The parotid gland overlies which muscle in the lateral face?
Medial pterygoid
Buccinator
Temporalis
Masseter
The parotid gland is situated superficially over the masseter muscle. The Stensen duct emerges from the anterior border of the gland to enter the oral cavity.
Which nerve runs through the parotid gland and divides it into superficial and deep lobes?
Glossopharyngeal nerve (IX)
Facial nerve (VII)
Auriculotemporal nerve
Vagus nerve (X)
The facial nerve traverses the parotid gland, dividing it into superficial and deep lobes. Its branches emerge from the gland to innervate muscles of facial expression.
Which bone forms the posterior part of the hard palate?
Nasal bone
Palatine bone (horizontal plate)
Vomer
Maxilla
The horizontal plates of the palatine bones form the posterior portion of the hard palate. The anterior portion is formed by the palatine processes of the maxillae.
Which branch of the maxillary artery supplies the temporal muscle?
Buccal artery
Middle meningeal artery
Deep temporal arteries
Inferior alveolar artery
The deep temporal arteries, anterior and posterior branches, arise from the maxillary artery to supply the temporalis muscle. They ascend in the temporal fossa deep to the muscle.
The mandibular foramen is located on which surface of the mandible?
Anterior body
Lateral aspect of the ramus
Medial aspect of the ramus
Coronoid process
The mandibular foramen is found on the medial surface of the ramus and allows passage of the inferior alveolar nerve and vessels. It is a key landmark for dental anesthesia.
The infratemporal fossa communicates with the pterygopalatine fossa via which opening?
Foramen ovale
Foramen rotundum
Pterygomaxillary fissure
Inferior orbital fissure
The pterygomaxillary fissure connects the infratemporal and pterygopalatine fossae, allowing passage of the maxillary artery and posterior superior alveolar nerves. It lies between the maxilla and pterygoid process of the sphenoid.
Motor innervation to the tensor veli palatini muscle is provided by which nerve?
Mandibular division of trigeminal nerve (V3)
Glossopharyngeal nerve (IX)
Facial nerve (VII)
Vagus nerve (X)
The tensor veli palatini is innervated by a branch of V3, unlike most other palatal muscles which receive motor fibers from the vagus via the pharyngeal plexus. It tenses the soft palate.
The accessory parotid gland tissue, when present, lies along the course of which duct?
Bartholin's duct
Wharton's duct
Stensen's duct
Rivinus ducts
Accessory parotid tissue is located on the path of the Stensen's duct over the masseter. Wharton's duct drains the submandibular gland, while Rivinus ducts are of the sublingual gland.
An accessory mental foramen can pose a risk during dental implant placement by altering the course of which structure?
Facial vein
Inferior alveolar artery
Mental nerve
Lingual nerve
An accessory mental foramen transmits branches of the mental nerve, and unrecognized variations may lead to nerve injury during mandibular procedures. The mental nerve provides sensation to the lower lip and chin.
Which muscle lies medial to the ramus of the mandible, contributing to the floor of the infratemporal fossa?
Temporalis
Medial pterygoid
Lateral pterygoid
Masseter
The medial pterygoid muscle attaches to the medial surface of the ramus, forming part of the infratemporal fossa floor. It acts to elevate and protract the mandible.
