Arteries Flashcards
Supplies structures within a he neck, face, and scalp, and also supplies the maxilla and tongue.
External carotid artery
It supplies the posterior two-fifths of the cerebrum, part of the cerebellum and brain stem.
Vertebrobasilar arteries
Circle of Willis
Terminal part of internal carotid artery (L and R)
Anterior cerebral artery ( LR)
Middle cerebral artery (LR)
Posterior cerebral artery (branch of basilar artery -LR)
Anterior communicating artery
Posterior communicating artery
Is a localized dilation of the internal carotid artery at its origin, the common carotid artery; “ sampling area” for maintaining blood pressure.
Carotid sinus
Detects changes in the composition of arterial blood flowing through it, mainly the partial pressure of oxygen
Carotid body
It measures changes in blood pressure and the composition of arterial blood flowing past it.
Aortic body
A temporary loss of consciousness that sometimes accompanies convulsive seizures because of the intensity of the carotid sinus reflex when pressure builds in one or both carotid sinuses.
Carotid sinus syndrome
One of the body’s homeostatic mechanisms for maintaining blood pressure. It provides a negative feedback loop…
Baroreflex
Subsequent changes in blood pressure are mediated by
Autonomic nervous system
What branch of internal carotid artery is most frequently implicated in a stroke?
Middle cerebral artery
These arteries are often called the “arteries of stroke”
Lenticulostriate arteries
A small blood vessel similar to capillaries but with a discontinuous endothelium. They are found in the liver, lymphoid tissue, endocrine organs and hematopoietic organs such as bone marrow and spleen.
Sinusoids
The tunica media is made up of: (2)
Smooth muscles ; elastic fibers
Are the smallest blood vessels responsible for exchange of substances between blood and interstitial fluid.
Capillaries
Small blood vessels supplying blood to the tissues of the larger vessels
Vasa Vasorum
Tunica media and adventitia are absent in what blood vessel type?
Capillaries
The hepatic veins that drain the liver empty into the:
Inferior vena cava
Are small veins that drain capillaries and deliver the blood to a vein.
Venules
Blood supply of palatine tonsils:
Dorsal lingual artery
Ascending palatine artery
Tonsillar branch (facial artery)
Ascending pharyngeal artery
Lesser palatine artery
What artery is found between the hypnosis and genioglossus muscles?
Lingual artery
Branches of lingual artery
Suprahyoid
Dorsal lingual
Sublingual
Deep lingual
Injection site for the IAN block is probed with a cotton tip applicator at the depth of the
Pterygomandibular space
If the palatial mucosa opposite to the maxillary first molar was lacerated and bleeding occurred, what artery is most likely to be involved?
Greater palatine artery
Examination of a patient with an ulcerative carcinoma of the posterior third of the tongue revealed bleeding from the lesion and difficulty swallowing (dysphagia). The bleeding was seen to be arterial; which of the following arteries was involved?
Dorsal lingual artery
What arteries supply the greater curvature of the stomach?
Right gastroepiplopic, left gastroepiplopic and short gastric arteries
The internal thoracic artery end in the sixt intercostal space by dividing into the:
Superior epigastric and musculophrenic arteries
At what level does the abdominal aorta bifurcate into the common iliac arteries and also give rise to the middle sacral artery?
L4
Is the main trunk of a series of vessels that convey the oxygenated blood to the tissues of the body for their nutrition.
Aorta
Supplies head, neck and upper limbs
Aortic arch
Brachiocephalic
Left subclavian
Left common carotid
The blood supply of the mucosa of the nasal septum is derived mainly from the:
Maxillary artery
The distal portion of the duodenum receives arterial supply form the inferior pancreaticoduodenal artery which branches from the:
Superior mesenteric artery
Upper limbs are supplied by the
Subclavian arteries ( L and R)
Head and neck are supplied by the
Right and left common carotid arteries
Anterior branches of the external carotid artery:
Superior thyroid artery
Lingual artery
Facial artery
Maxillary artery
Posterior branches of the external carotid artery:
Ascending pharyngeal artery
Occipital artery
Posterior auricular artery
Superficial temporal artery
What is the major arterial origin supplying the mandibular anterior teeth?
Maxillary artery
Normally arise off the side of the abdominal aorta, immediately below the superior mesenteric artery, and supply the kidneys with blood.
Renal arteries
Real arteries branch into smaller arteries:
Interlobar arteries - arcuate arteries - interlobular arteries - afferent arterioles ( leading to nephrons )
Urinary bladder is supplied by
Vesicular branches of the internalililac arteries
The subscapular artery which supplies the subscapularis muscle branches off the:
3rd part of axillary artery
The main blood supply to the brain stem and connects to the circle of Willis to potentially supply the rest of the brain if there is compromise to one of the carotids.
Basilar artery
Vertebrals give rise to:
Posterior inferior cerebellar artery
Basilar gives rise to:
Anterior inferior cerebellar artery and superior cerebellar artery
