Medium profile skull type (german sheperd) pyramid-shape head
mesaticephalic
Short profile skull type (french bulldog) skull as wide as it is short
brachycephalic
mandible is too long
prognathic jaw
mandible is too short

Three parts to the tongue
apex, body, root
Attachment of the tongue
frenulum
Conical and Vallate papillae
function for protection, surface area, grooming
Keratinized filiform papillae
cat
Choanae
caudal openings of the nasal cavities at the caudal end of the hard palate
Caudal limit of the nasopharynx
palatopharyngeal arches and caudal border of soft palate
Laryngopharynx rostral limit
palatopharyngeal arches
Oropharynx rostral limit
palatoglossal arches
Oropharynx caudal limit
base of epiglottis & root of tongue
Rostral limit of nasopharynx
choanae
Laryngopharynx caudal limit
pharyngoesophageal limen (begining of esophagus)
Functions of the larynx
protection against food aspiration, cough, phonation
4 cartilaginous structures of the larynx
epiglottis, thyroid, arytenoid, cricoid
Tongue and larynx and skull are connected via
the Hyoid apparatus
Cricothryroideus
tenses vocal fold (phonation)
-innervated by the cranial laryngeal n.
Thyroarytenoideus
constricts glottis
-innervated by caudal laryngeal n.
Cricoarytenoideus dorsalis
opens the glottis
-innervated by the caudal laryngeal n.
Slit in most rostral part of nose
philtrum
Parotid ln.
rostral to parotid salivary gland (difficult to discern from salivary gland on cadaver)
Mandibular ln.
ventral to mandibular salivary gland, straddles linguofacial v.
Palatine tonsil
- oropharynx, caudal to palatoglossal arch
- under semilunar fold
- drains oral cavity
- clinically relevant
Retropharyngeal ln.
b/t wing of atlas and larynx
Thyroid gland
- lateral to trachea, caudal to larynx
- separate lobes w/ occasional isthmus
Parathyroid gland
-cranial to thyroid gland, small
