Parotid Gland Flashcards
Anterior Tympanic Artery
Passes thru Petrotympanic Fissure
Supplies Middle Ear
Deep Auricular Artery
Passes thru Internal Auditory Meatus
Supplies Outer Ear and Tympanic Membrane
Middle Meningeal Artery
Passes thru Foramen Spinosum
Supplies Calvarium
Accessor Meningeal Artery
Passes thru Foramen Ovale
Supplies Calvarium
Inferior Alveolar Artery
Passes thru Mandibular Foramen
Supplies Lower Teeth
Deep Temporal Artery
Supplies Temporalis Muscle
Pterygoid Artery
Supplies medial and lateral pterygoid muscles
Masseteric Artery
Supplies masseter artery
Buccal Artery
Supplies cheek
Posterior Superior Alveolar Artery
Passes thru Posterior Superior Alveolar Foramen
Supplies posterior superior teeth
Descending Palatine Artery
Passes thru greater and lesser palatine foramen
Supplies palate
Artery of Pterygoid canal
Passes thru pterygoid canal
Supplies pharynx and auditory tube
Sphenopalatine Artery
Passes thru sphenopalatine foramen
Supplies nasal cavity
Infraorbital artery
Passes thru infraorbital foramen
Supplies anterior superior teeth
TMJ Ligaments
- Tempero-mandibular ligament- presents movement of mandible posteriorly and inferiorly
- Stylomandibular ligament
- Sphenomandibular ligament
Lock-jaw
Articular disc gets stuck anterior to the articular tubercle
Development of Parotid
Develops as a budding from ectoderm of the primitive mouth
Structures within Parotid Gland
- VII
- RMV
- External Carotid Artery
- Auriculotemporal nerve
Mumps
Viral infection of parotid cause painful swelling
*Compression of auriculotemporal nerve can cause ear pain
Drainage of Maxillary artery branches
Pterygoid venous plexus
Depression of mandible
- First, hinge joint of disc moves down
2. Then, articular disc slides back
