Cranial Nerve VII Facial
muscles of facial expression, taste, sublingal and submandibular salivary glands
Cranial Nerve VIII Vestibulocochlear
Sense of Balance and Hearing
Cranial Nerve IX Glossopharyngeal
taste and sensation for the posterior of tongue and parasympathetic innervation to the Parotid Gland
Cranial Nerve X Vagus
smooth muscles and glands of the body, cardiac muscle
Trigeminal Nerve V1 Opthalmic
leaves through superior orbital fissure of sphenoid bone
tip of nose, eyes, forehead
Trigeminal Nerve V2 Maxillary
leaves through foramen rotundum of sphenoid bone
upper teeth, nose, palate, mouth, cheek and temporal region
Trigeminal Nerve V3 Mandibular
leaves through foramen ovale of sphenoid bone
enters mandible foramen
includes muscles of mastication, and lower teeth
Medial Pterygoid OIF
insertion- inner surface of the angle of the mandible
function- elevate and protrude the mandible
Lateral Pterygoid OIF
insertion- TMJ disc and neck of the mandibular condyle
function- protrude and/or depress the mandible and allow the side to side shift of the mandible
Blood flow from the heart to the head
right side: brachiocephalic artery
left side: common carotid
right and left common carotids branch;
internal carotid: skull, eye, brain
external carotid: everything else
Blood flow to oral and facial structures
Maxillary: teeth, muscles of mastication, ear
Lingual: tongue, floor of mouth
Facial: muscles of facial expression, lips, eyelids, soft palate, throat
Deep Cervical Nodes
Frontal process builds what?
forehead and frontal bone
median nasal process
center and tip of nose
nasal septum
globular process
lateral nasal process
sides of nose
infraorbital area
First Brachial Arch builds what?
maxillary process
lateral palatine processes
upper parts of cheek
sides of upper lip
mandibular process
lower jaw
lower parts of the face and lower lip
anterior 2/3 of the tongue
Initiation (Bud Stage)
dental lamina grows in 20 spaces for primary teeth
Proliferation (Cap Stage)
enamel organ develops from the dental lamina
dental papilla arises and produces pulp and dentin
dental sac around the developing tooth becomes cementum, PDL and alveolar bone
Differentiation (Bell Stage)
enamel organ develops into 4 layers
Oral mucosa tissue
Masticatory mucosal tissue
protects attached gingiva and hard palate
Lining mucosal tissue
alveolar, vestivular and bucal mucosa, and floor of the mouth
Specialized mucosal tissue is where
Tooth with longest root
Cuspid most common with bifurcated root
Tooth most often fails to develop
Non-functional lingual cusp
Tooth most likely to have 2 root canals
Tooth most likely to have lingual caries
Mandibular first molar strongest root
Tooth with tendency to have divergent roots
Most unique anatomy tooth
First deciduous incisors erupt at
Primary dentition (20 teeth) complete by
Permanent tooth erupts about
mixed dentition stage lasts through age 12-13
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
