Terms Lab 22 (complete) Flashcards
platysma muscle
Large superficial muscle; covers the ventrolateral side of the head/neck
orbicularis oris muscle
Superficial muscle that encircles the mouth; attached to the lips
buccinator muscle
Deep muscle that encircles the mouth; considered a portion of the cheek
levator nasolabialis muscle
Superficial muscle located in the “bridge of the nose”
superior palpebrae
Upper eyelid
inferior palpebrae
Lower eyelid
palpebral fissure
Space between the eyelids
orbitcularos oculi muscle
Superficial muscle that encircles the orbit
conjunctival sac
The conjunctiva lined cavity where the eye sits
palpebral conjunctive
Inner surface of the eye lids
bulbar conjunctiva
Inner surface of the “eye socket”
dorsal and ventral lacrimal puncta
Minute orifice which collects tears; difficult to see without magnification
nasolacrimal duc
Duct that routes tears from the lacrimal puncta to the ventral nasal meatus
plica semilunaris
Third eyelid
rostral auricular muscles
Superficial group of muscles that control movement of the ear; rostral to the pinnae
caudal auricular muscles
Superficial group of muscles that control movement of the ear; caudal to the pinnae
vestibule (oral cavity)
Portion of the oral cavity inside the lips/cheeks up against the teeth/gums
oral cavity proper
Inner oral cavity
tongue (root, body, apex)
Body and apex are visible in the live dog’s mouth while the root is only visible in cadaver dissection
papillae
Microscopic structures on the tongue
papillae filiform
Small soft papillae covering the visible tongue; provide a mechanical function
papillae conical
Papillae that cover the root of the tongue; sharp and highly cornified provide mechanical function
papillae fungifrom
Large papillae; scattered among the filiform papillae; provide taste sensation
papillae foliate
Located on the caudolateral aspect of the tongue; limited visibility; provide taste sensation
papillae vallate
Very large papillae located at the junction of the body and the root of the tongue; only 4-6 total; arranged in a V-shape
sublingual caruncle
Located near the rostral frenulum; opening of salivary ducts
mandibular salivary gland
Large tight gland that lies in the branched V of the external jugular vein
mandibular and sublingual salivary duct
Large single duct that travels deeply just ventral to the tongue along with the lingual nerve; may be seem on the medial transected side
monostomatic sublingual salivary gland
Located deep near the cranial border of the mandibular salivary gland
parotid salivary gland
Superficial large gland that is located rostroventral to the ear
parotid duct
Duct from the parotid glad that runs along the lateral aspect of the masseter muscle
buccal salivary gland
Most visible in the cat; caudal to the last lower molar
palate
“Roof” of the oral cavity
incisive papilla
Elevation just caudal to the upper incisors; location of the opening of the incisive ducts
incisive duct
Communication between the oral and nasal cavities; travels to the vomeronasal organ
oropharynx
Space from the base of the tongue to the epiglottis; palatine tonsil is located here
palatoglossal arch
Fold of mucus membrane extending from the base of the tongue along the soft palate
palatine tonsil
Located in the oropharynx; covered with the semilunar fold
semilunar fold
Mucus membrane covering of the semilunar fold
nasopharynx
Extends from the caudal nasal cavity to the end of the soft palate
palatopharyngeal arch
Fold of mucosa at the caudal end of the nasopharynx
auditory tube
Small slit located in the nasopharynx
laryngopharynx
Dorsal to the larynx; esophagus is located at the caudal end
pharyngeal muscles
Swallowing muscles located around the larynx
