Cervical Angiology and Neurology Flashcards
Where does common carotid a. originate on the left and right?
Left: aorta
Right: brachiocephalic trunk
What is housed in the carotid sheath?
Common carotid a., internal jugular v., vagus n.
What does the posterior auricular a. supply? (4)
Parotid gland
Facial n.
Temporal bone
Auricular scalp
Ascending palatine a. supplies: (1)
Soft palate
Which artery supplies the submandibular gland?
Submental a.
What does the ascending pharyngeal a. supply? (4)
Pharynx
Anterior vertebral ms.
Middle ear
Cranial meninges
What does the vertebral a. and the deep cervical a. supply? (1)
Lateral and posterior neck ms.
Carotid sinus hypersensitivity syndrome
The carotid sinus can be hypersensitive to pressure which can lead to reduced HR and can cause someone to faint.
Which nerves do the carotid bodies relay info to adjust HR, RR and BP?
CN IX
CN X
The facial v. can drain into which veins?
Anterior jugular v.
Internal jugular v.
The retromandibular v. can drain in which veins?
Internal jugular v.
Communicating branch —> anterior jugular v.
Posterior auricular v. drains into:
External jugular v.
The communicating branch goes between which veins?
Retromandibular v. and anterior jugular v.
Where is the site for central line placement usually?
Subclavian v.
The external jugular venous pressure can approximate what?
It is internal barometer that can be used as a tool to dx HF, SVC obstructuction, etc.
Superficial lymph nodes drains into:
Deep inferior cervical LNs
Deep cervical LNs drain into:
Jugular lymphatic trunk
What does the right lymphatic duct drain?
Where does it empty?
ON THE RIGHT
Drains the jugular lymphatic trunk and subclavian trunk.
Empties into venous circulation where subclavian and internal jugular vs. unite.
What does the thoracic duct drain?
Where does it empty?
ON THE LEFT
Drains the jugular lymphatic trunk and subclavian trunk.
Empties into venous circulation where subclavian and internal jugular vs. unite.
Tonsils (3)
Lingual tonsils
Palatine tonsils
Pharyngeal tonsils (AKA adenoids)
What structures are in danger with a Tonsillectomy of the Palatine Tonsils? (3)
Tonsillar a.
CN IX
Internal carotid a.
What are tonsilloliths?
Tonsils stones. Calcifications that form in crypts of palatine tonsils.
What are the roots of the cervical plexus?
C1-C4/5
Root of lesser occipital n.
C2
Roots of great auricular n.
C2-C3
Roots of supraclavicular ns.
C3-C4
Roots of ansa cervicalis
Superior root
Inferior roots
C1-C3
Sup - C1 (travels w/ CN IX)
Inf - C2-C3
PSNS nerves in the cervical region (6)
From vagus n.
Pharyngeal branch Superior laryngeal n. Recurrent laryngeal n. N. to the carotid body Superior cardiac branch Middle cardiac branch
