Terms Lab 25 (complete) Flashcards
facial nerve
(cranial nerve VII) emerges just caudal to the external acoustic meatus; many branches swirl out from the origin
ventral buccal nerve
Branch of the facial nerve; travels along the ventral edge of the masseter muscle
dorsal buccal nerve
Branch of the facial nerve; travels along the across the dorsal part of the masseter muscle
auriculopalpebral nerve
Most dorsal branch from the facial nerve; short trunk
rostral auricular nerve branches
Caudal branch from the auriculopalpebral nerve (trunk))
palpebral nerve branches
Rostral branch from the auriculopalpebral nerve (trunk)
mandibular nerve
Trigeminal nerve (cranial nerve V) deep to the ramus of the mandible; many branches
lingual nerve
Most rostral branch of the mandibular nerve; longest branch; seen on the surface of the pterygoid muscles; travels ventrally to the tongue
inferior alveolar nerve
Middle branch of the mandibular nerve seen on the pterygoid muscles; passes into the mandibular foramen in the medial aspect of the ramus
maxillary nerve
Travels across the pterygoid muscles ventral to the orbit
infraorbital nerve
Continuation of the maxillary nerve
vagus nerve
Cranial nerve (X) travels in the carotid sheath as the vagosympathetic trunk
cervical sympathetic trunk
Portion of the vagosympathetic trunk?
cranial cervical ganglion
Located deep; ventral to the external acoustic meatus
hypoglassal nerve
Cranial nerve VIII emerges caudoventral to the external acoustic meatus; travels to the root of the tongue over the hypoglossus muscle
thyroid gland
Located in the neck along the common carotid artery and trachea
external and internal parathyroid glands
Located on the thyroid gland; small round gland
esophagus
Tube
trachea
Cartilaginous tube
tracheal cartilages
Present on trachea
medial retropharyngeal lymph node
Huge LN located just caudal to the mandibular salivary gland; caudoventral to the external acoustic meatus; mostly deep
common carotid artery
Large deep artery that travels cranially from the neck; slightly deep
internal carotid artery
Dorsal branch from the common carotid artery
carotid sinus
Small dilation in the internal carotid artery
external carotid artery
Ventral branch from the common carotid artery
occipital artery
Ventral branch from the external carotid artery; runs along side the internal carotid
lingual artery
Ventral branch from the external carotid artery
facial artery
First ventral branch from the maxillary artery; medial to the digastric muscle
sublingual artery
Branch of the facial artery; travels the medial aspect of the mandible
maxillary artery
Continuation of the external carotid artery; travels deep near the pterygoid muscles
inferior alveolar artery
Second branch from the maxillary artery; cranial to the facial artery
external ophthalmic artery
Tiny artery that branches from the maxillary artery; enters the periorbita to supply muscles
infraorbital artery
Continuation of maxillary artery as it travels through the infraorbital foramen
