Head Anatomy
These 3 hard tissues are involved with teeth
What are dentin, enamel, and cementin
These 3 CN travel through the tympano-occipital fissure
What are the Glossopharyngeal nerve (CN IX), Vagus nerve (CN X), and Accessory nerve (CN XI)
The dental formula 2(I 3/3, C 1/1, P 4/4, M 2/3) is for this species
What is canine
This muscle opens the palpebrae (eyelid)
What is levator labii superioris
These canine teeth have no deciduous teeth (Hint: There's 4 total)
What are PM 1, M1-3
This CN does visceral motor innervation to the sublingual and mandibular salivary glands as well as the lacrimal gland
What is the Facial nerve (CN VII)
General sensory innervation to the caudal tongue is supplied by this nerve
What is the glossopharyngeal nerve (CN IX)
Sympathetic innervation reaches the head using this ganglion
What is the cranial cervical sympathetic ganglion (CCSG)
Cricoarytenoideus lateralis muscle performs this action
Adduction of the larynx
These 3 cartilages make up the external ear
What are auricular cartilage, annular cartilage, and scutiform cartilage
The Adbucens nerve (CN VI) supplies somatic motor innervation to these 2 muscles
What are lateral rectus and retractor bulbi muscles
The term for different shape teeth for different functions/tasks
What is heterodonty
The stylopharyngeus muscle performs this action
What is dilates the pharynx
The surface that opposing teeth come in contact with
What is the occlusal surface
These 2 muscles act to retract the hyoid bones
What are sternohyoideus and thyrohyoideus muscles
Due to the orbit being not fully closed in the dog, this structure helps keep the eye in place
What is the orbital ligament
The lingual artery can be identified traveling alongside this nerve
What is the hypoglossal nerve (CN XII)
The Glossopharyngeal nerve (CN IX) does visceral motor innervation to what structures?
What are parotid and zygomatic salivary glands
This artery enter the caudal alar foramen, travels through the alar canal, and exits via the rostral alar foramen
What is the maxillary artery
This CN nerve travels through the internal acoustic meatus
What is the Vestibulocochlear nerve (CN VIII)
This is the only sensory branch coming from the Facial nerve (CN VII), thus making it a mixed nerve
What is the chords tympani branch
Normal occlusion is demarcated by this relationship between upper and lower teeth
What is upper teeth slightly more rostral than lower teeth
The brain is supplied by these 2 arteries
What are the internal carotid artery and vertebral artery
This CN does somatic motor innervation to the eye, specifically to the dorsal oblique muscle
What is the trochlear nerve (CN IV)
These 3 muscles are extrinsic muscles of the larynx
