Arteries of the Head & Neck Flashcards
Arteries carry (oxy/deoxy) blood to their target destinations
oxygenated
Veins drain (deoxy/oxy) blood backk to the superior vena cava and from there to the heart and then lungs for reoxygenation
deoxygenated
Largest blood vessel in the body. Arises directly from the heart and descends through the thorax into the abdomen. Source of most arteries of the body and all of the arteries of the head and neck
The aorta
Arising from the right side of the aorta is the _________ artery.
brachiocephalic
From the brachiocephalic artery we get the ________ and the _________
Right carotid artery
Right subclavian artery
From the left side of the aorta we get the _____ and ______
Left carotid artery
Left subclavian artery
The significance of the subclavian arteries
give rise to the left and right vertebral arteries which pass through the transverse foramina of the spinal column and enter the cranium through foramen magnum to form the basilar artery
The right and left vertebral arteries will join in the head to form the
basilar artery
On the right side, the right common carotid branches off the ______ artery
brachocephalic
On the left side, the common carotid artery branches off the
Aorta
External carotid artery branches off of the
common carotid artery
Right common carotid artery arises from the right brachiocephalic artery and then bifurcating into the _____ & _____ at the level of thyroid cartilage
internal and external carotid arteries
These branch off what artery
- Superficial temporal
- Maxillary
- Facial
- Lingual
- Superior thyroid
- Ascending pharyngeal
- Posterior auricular
- Occipital
External Carotid Artery
External carotid artery provides oxygenated blood to the
superficial neck, face and scalp
Supplies thyroid
superior thyroid
Supplies pharynx
Ascending pharyngeal
Supplies tongue
Lingual
Supplies face up to the orbit
Facial
Supplies muscles of neck and scalp over occipital region
Occipital
Supplies scalp behind auricle of ear, the ear itself, and muscles on the base of the skull
Posterior auricle
