|
What does the palatoglossal fold course between?
|
It courses between the tongue and soft palate and forms the caudal boundary of the oral cavity and cranial boundary of the oropharynx.
|
|
|
What is the ventral divider of the tongue?
What is the stretch receptor within the tongue? |
The lingual frenulum and the lyssa, respectively.
|
|
|
What are the four major salivary glands?
Are they compound or simple glands? What differentiates them from minor salivary glands? |
Parotid, mandibular, zygomatic, and sublingual.
These are complex glands and are different from minor salivary glands as the minor ones aren't part of a network of glands covered by a unifying dense, irregular connective tissue dumping into one excretory duct along the way. |
|
|
What muscle does the parotid salivary gland course over?
Where does it drain? |
The masseter m.
It drains through the parotid duct into the vestibule of the oral cavity via the parotid papilla at the level of the caudal margin of the 4th upper premolar. |
|
|
Where is the zygomatic salivary gland located?
Where does it drain? |
It is located ventral to the eye deep to the zygomatic arch.
It drains through the main and minor zygomatic ducts into the vestibule via the zygomatic papilla near the last molar. |
|
|
Where is the mandibular salivary gland located?
Where does it drain? |
It is located caudal to the angle of the mandible, between the maxillary and linguofacial veins.
It drains into the floor of the oral cavity at the sublingual caruncle. |
|
|
Where is the sublingual salivary gland located?
Where does it drain? |
The sublingual salivary gland has two divisions, the monostomatic and polystomatic.
The monostomatic sublingual salivary gland is closely related to the rostral end of the mandibular salivary gland, but extends farther rostrally. These glands drain into the sublingual caruncle. The polystomatic sublingual salivary gland are small lobules located beneath the oral mucosa on each side of the body of the tongue. They drain into microscopic ducts that open directly into the oral cavity. |

|
Where are the sublingual caruncles located, what drains from them?
|
They are located to either side of the lingual frenulum. The monostomatic sublingual and mandibular salivary ducts drain from them.
|
|
|
Where are the mandibular lymph nodes located? Are they palpable? What do they drain and where do they drain into?
|
They are located to either side of the linguofacial or lingual v. They drain the superficial structures of the face and intermandibular area into the medial retropharyngeal ln.
|
|
|
Where are the parotid lymph nodes located? Are they palpable? What do they drain?
|
They are located on the caudal border of the masseter muscle rostral to the parotid salivary gland.
They are not always palpable and drain the superficial structures of the head dorsal to the palate and ear. |
|
|
Which is larger, the medial or lateral retropharyngeal lnn.?
|
The medial ln is larger.
|
|
|
Is the vomeronasal organ paired?
Where is it located? What is it composed of? What role does the vomeronasal organ play? |
The vomeronasal organ is a paired structure located in the rostral base of the nasal septum. It is composed of specialized olfactory epithelium that detects pheromones. Thereby it plays a role in sexual behavior and social communication.
|
|
|
What is the Flehman response?
|
The olfactory reflex, or lip-curl.
|
|
|
Where does the vomeronasal organ open into the oral cavity?
|
The oral opening of the incisive ducts are located lateral to the incisive papilla.
|
|
|
What are the individual incisors called?
|
Central, intermediate, and corner.
|
|
|
Which are longer in canine teeth, the root or the crown?
|
The root.
|
|
|
What are the carnassial teeth?
|
AKA sectorial or shearing teeth, these are the upper P4 and lower M1.
|
|
|
What is the carrying space?
|
The space between the maxillary and mandibular premolars that do not meet.
|
|
|
What is the occlusal, or masticating, surface of a tooth?
|
The surface of a tooth that occludes with or contacts an opposing surface of a tooth in the opposing jaw.
|
|
|
What are the two vestibular surfaces of teeth?
|
The labial and buccal surfaces.
|
|
|
What is the difference between the lingual and palatine surface of teeth?
|
The lingual surface is the inner surface of the mandibular teeth and the palatine surface is the inner surface of the maxillary teeth.
|
|
|
What is the formula for the permanent and deciduous dentition in the dog?
|
Permanent:
2 (I 3/3, C 1/1, PM 4/4, M 2/3) = 42 teeth Deciduous: 2 (I 3/3, C 1/1, PM 3/3) = 28 teeth |
|
|
Name the tables in the diner.
|
100 - right permanent maxillary and incisive teeth.
200 - left permanent maxillary and incisive teeth 300 - left permanent mandibular teeth. 400 - right permanent mandibular teeth. 500 - right deciduous maxillary and incisive teeth. 600 - left deciduous maxillary and incisive teeth. 700 - left deciduous mandibular teeth. 800 - right deciduous mandibular teeth. |
|
|
Name the roots of the canine mouth.
|
Upper arcade:
Incisors - 1 Canine - 1 P1 - 1 P2, P3 - 2 P4, M1, M2 - 3 Lower Arcade: Incisors -1 Canine - 1 P1 - 1 P2, P3, P4, M1, M2 - 2 M3 - 1 |
|
|
What is the formula for the permanent and deciduous dentition in the cat?
|
Permanent:
2 (I 3/3, C 1/1, PM 3/2, M 1/1) = 30 teeth Deciduous: 2 (I 3/3, C 1/1, PM 3/2) = 24 teeth |
|
|
What premolar do cats not have?
|
PM1
|
|
|
In the cat, what fills the space between the lower canine and lower P3 when the mouth is closed?
|
The upper canine and upper P2.
|
|
|
What are the numbers of roots per tooth in the cat?
|
Upper arcade:
Incisors: 1 Canine: 1 P2: 1 P3: 2 P4: 3 M1: 2 Lower arcade: Incisors: 1 Canine: 1 P3, P4, M1 - 2 |
|
|
In a normal bite in both dogs and cats, how are the upper and lower incisors related to each other in terms of which is rostral to the other?
|
The upper incisors are rostral to the lower incisors.
The lower canines are rostral to the upper. |
|
|
What are the two types of malocclusions?
|
Brachygnathism - parrot mouth - overbite to the mandibles failing to develop fully.
Prognathism - under bite; common to brachycephalic breeds. Occurs when maxilla growth is stunted. |
