exam 2: Head and neck vessels Flashcards
From the aortic arch, what does it turn into
Brachiocephalic trunk
what does the Brachiocephalic trunk divide into
Subclavian aa. and Bicarotid trunk
what are ALL of the branches off of the Subclavian aa
- Axillary a.
- Internal thoracic a.
- Vertebral a.
- Superficial cervical a.
- Left Deep cervical a.
(Right from Costocervical. T) - Costocervical T
what are the branches off of the Subclavian aa that supply the neck and head
- Vertebral a.
- Superficial cervical a.
- Left Deep cervical a.
(Right from Costocervical. T)
what does the Bicarotid trunk divide into that go to supply the head
Right & left Common carotid aa
what does the verterbral a. supply
runs in transverse foramina going up to the atlas
supplies the brain
what does the superficial cervical supply
located in jugular fossa, supplies caudal base of the neck (like pectoral muscles)
what does the Left Deep cervical a.
(Right from Costocervical. T) supply
Deep medial structures of the neck
very close to the nuchal ligament
what is the most important artery/arteries that supply the head
Right & left Common carotid aa.
what are the branches off of the Facial a.
- Angularis oculi a.
- Dosal nasal a.
- Lateral nasal a.
- Superior labial a.
- Inferior labial a.
- Sublingual a
Angularis oculi a. supplies
medial canthus of the eye, orbicularis oculi m.
Dosal nasal a. and Lateral nasal a. supplies
the nose
Superior labial a. and Inferior labial a supply the
lips
Sublingual a. supplies
floor of the oral cavity
what does the linguofacial trunk splint into
Ligual and facial a.
what does the common carotid branch into
external and internal carotid aa.
what branches off of the superficial temporal m.
transverse facial a
superficial temporal (continuation)
rostral auricular a.
what do the Caudal auricular a. and Rostral auricular a. supply
the ear
what are the 3 arteries we can use in a horse to palpate a pulse
Transverse facial a.
Masseteric a.
Facial a.
what is the MAIN blood supply to the brain
internal carotid a.
what does the masseteric a. supply
masseter muscle
vertebral a. (in transverse foramina)
what is she doing
Using facial a. to take the pulse
what are they doing
getting a pulse using the transverse facial a.
what boney process should you follow to find the transverse facial a.
zygomatic arch (artery runs ventral to it)
what is the tracheal duct associated with the lymph nodes of a horse
where lymph from the head travels
can you palpate the Lateral retropharyngeal Lnn
only if enlarged, very deep LN’s
Superficial cervical LN’s are also known as
pre-scapular
what is unique about the mandibular LN’s in a horse compared to a dog
Right and Left are joined in the intermandibular space
more rostral and medial compared to dogs
what is affecting blood flow when a horse eats like this
gravity is impacting blood flow in vessels
what is unique in the horse regarding the transverse facial, deep facial, and buccal vein
they also have sinuses
what does it mean for the transverse facial, deep facial, and buccal veins to have a sinus
expansion/sac in the vein that acts as a “pump” pushing blood towards External jugular
what muscle is between the external jugular v. and the carotid sheath, only in horses (not in dogs)
omohyoideus m.
what is important to remember when getting a blood sample from the external jugular vein
the common carotid is VERY CLOSE BY
guttural pouch
what are the forceps holding
Forceps is holding the medial
membranous wall of guttural pouch
bone dividing the guttural pouch in a lateral (LC ) and medial (MC) compartments
Stylohioid bone
T/F Longus capitis m. serves as a dorsal/medial border of the guttural pouch
true
which is the medial which is the lateral compartment
green- lateral compartment
blue- medial compartment
