1.8: Anatomy 3 and 4 Flashcards
Label this diagram (A-E?)
A = Hard Palate
B = Nasal Cavity
C = Oral Cavity
D = Tongue
E = Soft Palate
Label this diagram (F–>J)?
F = Oropharynx
G = Epiglottis
H = Hyoid Bone
I = Muscles of the floor of the mouth
J = Mandible
Label this diagram?
A = Left Sublingual Fold
B = Sublingual Papillae (Opening for the ducts of the submandibular salivary gland)
C = Frenulum
Label this diagram?
A = Parotid Gland
B = Submandibular Gland
C = Parotid Duct
D = Submandibular Duct
E = Sublingual Duct
F = Sublingual Gland
Label this diagram?
A = Parotid Duct
B = Buccinator
C = Sublingual Ducts
D = Sublingual Gland
E = Muscles of the floor of the mouth (Mylohyoid)
F = Submandibular Gland
G = Masseter
H = Parotid Gland
What supplies the submandibular gland?
CN VII Parasympathetic Axons
What supplies the sublingual salivary gland?
CN VII`
What supplies the parotid gland?
CN IX (Hitches a ride on the branches of CN V3)
Describe how the tongue is divided up?
Anterior 2/3rds
Posterior 1/3rd
Describe the nerve supply to the anterior 2/3rds of the tongue?
General Sensory = CN V3 (mandibular)
Special Sensory = CN VII (facial)
Describe the nerve supply to the tongue?
General and sensory = CN IX
Glossopharyngeal
What is the foramen caecum?
Part of the tongue
Origin of the thyroid gland
Found at the apex of the terminal groove
Label this diagram?
A = Foramen Caecum
B = Vallate Papillae
C = Surface Texture Papillae
Describe what the vallate papillae do? Where are they?
What do the surface texture papillae do? Where are they?
Vallate papillae = contain taste buds - back of tongue
Surface texture papillae = General sensory, temperature, touch - front of tongue
Describe how thyroid swellings move on swallowing?
Why?
Thyroid swellings move SUPERIORLY then INFERIORLY due to attachment to the larynx
Name the extrinsic tongue muscles?
Palatoglossus
Styloglossus
Genioglossus
Hyoglossus
Name these muscles
A = Genioglossus
B = Hyoglossus
C = Palatoglossus
D = Styloglossus
Name this muscle?
Genioglossus
Describe the nerve supply to the tongue muscles?
Mostly supplied by the hypoglossal nerve (CN XII)
How can you clinically text CNXII?
- Ask patient to stick tongue straight out
- If tongue is straight, then both CNXIIs are normal
- If tongue deviates away from midline, the side it deviates towards is the affected side
What is the blood supply to the tongue?
Lingual Arteries (right and left)
Label this diagram A–F?
A = Upper Lip
B = Vermillion Border
C = Palatine Tonsil
D = Posterior Wall of Oropharynx
E = Gingivae
F = Lower Dental Arch
Label this diagram?
- F, G, H and I?
F = Lower Dental Arch
G = Uvula
H = Arches of Soft Palate
I = Upper Dental Arch
