The auriculotemporal nerve runs posterior to the TMJ and close to the neck of the condyle. Injury may cause paresthesia of the temple and Frey syndrome.
Which nerve lies close to neck of condyle and is at risk during TMJ surgery?
1) Facial nerve
2) Auriculotemporal nerve
3) Lingual nerve
4) Buccal nerve
A well-defined or heart-shaped radiolucency larger than approximately 6-8 mm in the midline between vital maxillary central incisors suggests a nasopalatine duct cyst.
On maxillary periapical, corticated radiolucency in midline greater than 8 mm between central incisors with vital teeth suggests:
1) Normal nasopalatine foramen
2) Nasopalatine duct cyst
3) Radicular cyst
4) Median palatine suture
The glossopharyngeal nerve exits the skull through the jugular foramen, along with the vagus and accessory nerves.
The glossopharyngeal nerve exits via:
1) Jugular foramen
2) Foramen ovale
3) Stylomastoid foramen
4) Hypoglossal canal
The floor of the posterior triangle is formed by prevertebral muscles covered by prevertebral fascia, including splenius capitis, levator scapulae, and the scalene muscles.
Which muscle forms floor of posterior triangle?
1) Prevertebral muscles covered by prevertebral fascia
2) Infrahyoid muscles
3) Mylohyoid
4) Buccinator
The upper part of the posterior triangle, bounded by sternocleidomastoid, trapezius, and the inferior belly of omohyoid, is the occipital triangle.
The triangle bounded by sternocleidomastoid, omohyoid and trapezius is:
1) Carotid triangle
2) Muscular triangle
3) Occipital triangle
4) Submental triangle
The parotid duct runs anteriorly across the masseter and crosses adjacent to the buccal branch of the facial nerve before piercing the buccinator muscle.
Which branch of the facial nerve does the parotid duct cross?
1) Buccal branch
2) Temporal branch
3) Zygomatic branch
4) Marginal mandibular branch
The true capsule of the thyroid gland is formed by a condensation of the gland's own connective tissue. The pretracheal fascia forms the false capsule.
The true capsule of the thyroid gland is derived from:
1) Carotid sheath
2) Connective tissue of gland
3) Pretracheal fascia
4) Deep cervical fascia
The maxillary and superficial temporal veins unite to form the retromandibular vein. It then divides into anterior (joins facial to form common facial) and posterior (joins posterior auricular to form external jugular) divisions.
Retromandibular vein formed by union of:
1). Superficial temporal + Maxillary vein
2). Facial + Lingual
3). Lingual + Superior thyroid
4). Posterior auricular + Occipital
