Exam II - Canine Head VAN Flashcards
Which artery runs with the hypoglossal n?
lingual a.
After superficial temporal a. branches off, external carotid a. becomes __________
maxillary a.
There is a swelling at the base of the internal carotid a. What is this swelling and what does it do?
This is the carotid sinus It acts as a baroreceptor to monitor blood pressure
This structure acts as a chemoreceptor and is located at the bifurcation of the internal and external carotid arteries
Carotid body
The maxillary a. enters the caudal alar foramen, travels throught the alar canal, and exits through the _____________
Rostral alar foramen
After leaving the infraorbital canal, the **maxillary a. **becomes the ____________
infraorbital a.
This artery supplies the cranial portion of the thyroid gland:
cranial thyroid a.
This artery supplies muscles on the caudal aspect of the skull and meninges:
occipital a.
This artery supplies the tonsil & tongue and runs with the hypoglossal n:
lingual a.
This artery is medial to the digastricus, and supplies the lip and nose:
facial a.
This artery supplies the parotid gland, masseter & temporal mm, rostral auricular mm, and eyelids:
superficial temporal a.
This artery is vetnral, caudal to the hard palate; goes to soft and hard palates:
**minor palatine a. **(off of maxillary a.)
This artery enters the caudal palatine foramen and passes through the major palatine canal to supply the hard palate:
major palatine a. (off of maxillary a.)
This venous structure drains blood from the tongue, the larynx, and part of the pharynx
lingual v.
This venous structure drains the ear, orbit, palate, nasal cavity, cheek, mandible, and cranial cavity
maxillary v.
The _____ is referring to the cavity within which the eyeball sits
The orbit is referring to the cavity within which the eyeball sits
Identify the maxillary vein
There it is
Identify the external jugular vein
The internal carotid a. is absent in which species?
bovine & feline
After superficial temporal a. branches off, external carotid a becomes maxillary a. Maxillary dives deep an heads through the __________ canal and comes out the ____________. It then transverses the skull before heading into the ____________.
After superficial temporal a. branches off, external carotid a becomes maxillary a. Maxillary dives deep an heads through the alar canal and comes out the rostral alar foramen. It then transverses the skull before heading into the maxillary foramen.
After maxillary a. enters the infraorbital canal, it exits the infraorbital foramen as _____________.
After maxillary a. enters the infraorbital canal, it exits the infraorbital foramen as infraorbital artery.
What is tagged in this picture?
Mandibular salivary gland
What is the anatomical landmark for cervical nerve 2?
wing of the atlas
The great auricular nerve is going to supply some cutaneous innervation to the caudal aspect of the ear. There are a ton of different procedures that get done on the ear and we will need good nerve blockage associated with these procedures. You can very easily block the great auricular nerve by palpating the wings of the atlas and doing a block in the area where C2 exits - this will give you a complete blockade of the caudal aspect of the ear.
In which species do we not have a complete orbit?
canine
the dorsal lateral aspect is non-bony and instead has a ligament that closes it off
inflammation of the nictitating membrane is known as __________
cherry eye
Which vein drains the dorsal surface of the muzzle?
Facial v.
