H&n Cerebral Arteries

Front 1

Which two primary systemic arteries supply the brain?

Back 1

vertebral and internal carotid

Front 2

Vertebral artery is a branch of?

Back 2

the subclavian artery

Front 3

Circle of Willis

Back 3

the branches of the vertebral and internal carotid arteries and their anastomoses that provide blood for the brain

Front 4

Branches of vertebral artery

Back 4

anterior spinal artery, posterior spinal artery, posterior inferior cerebellar artery, basilar artery

Front 5

Branches of the basilar artery

Back 5

anterior inferior cerebellar arteries, labyrinthine arteries, posterior cerebral arteries, pontine arteries

Front 6

Branches of the internal carotid

Back 6

middle cerebral artery, anterior cerebral artery, ophthalmic artery, superior hypophyseal artery

Front 7

Anterior communicating artery

Back 7

an anastomoses branch connecting the two anterior cerebral arteries

Front 8

Posterior communicating artery

Back 8

an anastomoses branch connecting the posterior and middle cerebral arteries

Front 9

Where the anterior cerebral artery supplies blood

Back 9

anterior aspect of frontal lobe

Front 10

Infarctions of the anterior cerebral artery cause

Back 10

weakness: contralaterally in the lowerlimb (arms and face spared); sensory loss in contralateral lower extremity; change in behvaior and loss of bowel and bladder function and changes in socio-sexual behavior

Front 11

Posterior cerebral artery supplies blood to

Back 11

thalamus, upper portion of brain stem, occiptal lobe, inferior part of temporal lobe

Front 12

Infarction of the posterior cerebral artery causes

Back 12

contrallateral hemi/quadrantanopsia (loses half or quarer of vision), disturbance in memory and behavior, dense loss of sensation on entire contralaterl side, inconsistent lsses of movement, disorders of eye movement and consciousness

Front 13

Middle Cerebral artery supplies blood to

Back 13

bulk of lateral aspect of cerebral hemispheres and much of deep strctures as well

Front 14

When proximal stem of middle cerebral artery is occluded

Back 14

weakness: contralateral w/ lower limb somewhat spared; total contralateral sensory loss; specific disorders of motor planning; disorders of language, writing, vision, reading; spatial disorders including dysfunction referred to as neglect

Front 15

Lenticulostriate branch of middle cerebral artery supplies blood to

Back 15

large portion of basal ganglia and internal capsule; known as The Artery of Stroke

Front 16

Occlusion of lenticulostriate branch of middle cerebral artery causes

Back 16

weakness: could be totally contralaterally; sensory loss throughout the contralateral side; dysarthria )imperfect articulation of speech)

Front 17

Symptoms of blockage of the anterior cerebral artery?

Back 17

Contralateral weakness and sensory loss in lower limb. Also, loss of bladder and bowel function.

Front 18

What structures does the posterior cerebral artery supply?

Back 18

Thalamus and upper portion of the brainstem, as well as occipital lobe and inferior temporal lobe

Front 19

Symptoms of blockage of posterior cerebral artery?

Back 19

Contralateral hemi- or quadrantanopsia, disturbance in memory and behavior, contralateral loss of sensation, disorders of eye movements.

Front 20

What structures does the middle cerebral artery supply?

Back 20

Bulk of the lateral aspect of cerebral hemispheres and many deep structures as well.

Front 21

Symptoms of blockage of middle cerebral artery?

Back 21

Contralateral weakness (lower limb spared) and sensory loss. Motor planning, language, writing, reading, and vision disorders. Spatial dysfunction (neglect).

Front 22

Symptom of blockage of lenticulostriate branch of middle cerebral artery?

Back 22

Total contralateral weakness and sensory loss, and dysarthria (imperfect articulation of speech)

Front 23

What is the first area of the brain to be affected by acute hypoxia?

Back 23

Hippocampus

Front 24

What are the branches of the internal carotid?

Back 24

Opthalmic artery, superior hypophyseal arteries, anterior choroidal artery, middle and anterior cerebral arteries.

Front 25

What sinus do the emissary and diploic veins drain into?

Back 25

Superior sagittal sinus (diploic drain scalp bones, and emissary drain the scalp)

Front 26

Which structures abut or travel through the cavernous sinuses?

Back 26

Internal carotid, CN III, IV, V1/V2, VI. THe optic nerves and chiasm lie superior.
