A
  • The Posterior Boundary of the oral cavity
19
Q

What Innervates the Oral Cavity?

A
  • Upper Half: V2 (maxillary) branch of the CV: Trigeminal

- Lower Half: V3 (mandibular) branch of the CV: Trigeminal

20
Q

What supplies blood to the Oral Cavity?

A
  • Branches of the External Carotid
21
Q

What are the Features and Parts of the Teeth? What is their composition?

A
Features
- Crown
- Neck (in touch with the gum)
- Root (within the alveolar bone of the jaw)
Composition
- 3 Calcified Tissues
22
Q

What is the core of the teeth made of?

A
  • Dentin
23
Q

Describe the structure of dentin? What produces it?

A

Structure
- Very hard: cannot resist against physical and chemical stresses
Produced by
- Group of cells that are maintained in the body; therefore, damage can be repaired

24
Q

What is Enamel?

A
  • Covers the core of the crown (hardest part of the body) (pearl white in color)
25
Q

Can Enamel be repaired?

A
  • No (can not be repaired or reproduced after the eruption of teeth)
26
Q

What are the Cementum?

A
  • covers the core in the root
27
Q

Where is the Pulp Cavity? What is it filled with?

A

Location
- Within the Dentin Core
Filled With
- Nerves and Vessels

28
Q

What is a root Canal?

A
  • The Extension of the Pulp Cavity into the Root
29
Q

What is the Periodontal Ligament?

A
  • Binds the root to the alveolar bone
30
Q

What are the Teeth innervated by? What supplies blood to the teeth?

A

Innervated
- Cranial Nerve V: Trigeminal
Blood Supply
- Branches of External Carotid

31
Q

What is the Tongue separated by?

A
  • A terminal sulcus
32
Q

What are the two sides of the tongue that are separated by the terminal sulcus?

A
  • The Root of the Tongue (aka: the posterior 3rd of the tongue or the pharyngeal tongue)
  • The Body of the Tongue (aka: the anterior 2/3rds of the tongue or the oral part)
33
Q

What are the Lingual Papillae?

A
  • Circumvallate Papilla
  • Foliate Papilla
  • Fungiform Papilla
  • Filiform
34
Q

Where are the Circumvallate Papilla located?

A
  • Epithelial elevations in front of the terminal sulcus
35
Q

Where are the Foliate Papilla located?

A
  • On the sides of the tongue
36
Q

Where is the Fungiform Papilla located?

A
  • On the Dorsal Surface Anteriorly
37
Q

Where are the Filiform located? What is their purpose?

A

Location
- Everywhere on the tongue
Function
- Not Tastebuds; They add to the friction of the tongue to make chewing of the bolus more efficient

38
Q

What is the Tongue Tissue composed of?

A
  • Anterior 2/3rds: skeletal muscle

- Posterior Part: Lymphoid tissue, organized into pairs of lingual tonsils

39
Q

What innervates the Tongue?

A
