Anatomy Flashcards
Lingual Nerve Position
Between medial pterygoid and mandible
What is medial to zygomatic arch
Masseter
Rotation direction of condyle on working side
Vertical
Curve of Monson
Combination of Curve of Speed and Curve of Wilson
Curve of Wilson
Occlusion of posterior teeth conform to a curved plane
Curve of Spee
Upwards inclination of mandibular posterior teeth
Spaces for initial odontogenic infection (5)
- Pterygomandibular
- Infratemporal
- Deep temporal
- Superficial temporal
- Masseteric
Where is the lingual plate thinner than the buccal plate
Lower 8s
Exit points for the 3 branches of the trigeminal nerve
Supra-orbital notch
Infra-orbital foramen
Mental foramen
Where must trauma have occurred if all branches of CN V are affected (3)
Base of the skull

Cervical
Orbitomeatal line
Outer canthus of eye to centre of external auditory meatus
Origin of masseter (2)
Superficial part - Zygomatic arch
Deep part - Zygomatic arch of temporal bone
Insertion of masseter
Angle of mandible
Action of masseter
Elevates mandible
Innervation of masseter
Mandibular nerve
V3
Origin of temporalis
Temporal fossa of the skull
Insertion of temporalis
Coronoid process of mandible
Action of temporalis (2)
Elevates mandible
Retraction of mandible
Innervation of temporalis
Mandibular nerve
V3
Origin of medial pterygoid (3)
Superficial - Maxillary tuberosity and pyramidal process of palatine bone
Deep - Medial aspect of lateral pterygoid plate of sphenoid bone
Insertion of medial pterygoid
Ramus of the mandible near the angle
