the lateral striate (denticulate) arteries supply?
|
anterior limb of internal capsule, genu, and most of posterior limb
|
|
|
The genu of the internal capsule receives blood supply from the
|
anterior choroidal artery as well as the lateral striate (lenticulostriate) arteries.
|
|
|
The anterior limb of the internal capsule receives blood supply from the?
|
lateral striate (lenticulostriate) arteries and middle
|
|
|
the posterior limb of internal capsule receives blood from the?
|
lateral striate (lenticulostriate) arteries. and most inferior part anterior choridoal artery
|
|
|
where do lateral striate (lenticulostriate) arteries arise from
|
m1 segment of middle cerebral
|
|
|
an occlusion of anterior cerebral results in the anterior choroidal artery syndrome which is defined by:
|
homonymous hemianopsia (damage to optic tract) on the side opposite the lesion, a hemihypesthesia or hemianesthesia (damage to thalamocortical fibers) and a contralateral hemiplegia (damage to corticospinal fibers); the later two deficits relate to the infarcted area including portions of the posterior limb of the internal capsule. Variations on this overall theme may occur.

|
A lesion involving the crus and the oculomotor root results in a
|
superior alternating hemiplegia
|
|
|
The blood supply to corticospinal fibers in the crus cerebri is
|
via penetrating branches of the basilar bifurcation and of the P1 segment.
|
|
|
A lesion involving the root of the abducens nerve and the adjacent corticospinal fibers results in a
|
middle alternating hemiplegia
|
|
|
A lesion involving the hypoglossal root and corticospinal fibers in the pyramid results in an inferior alternating hemiplegia
|
inferior alternating hemiplegia
|
|
|
results in a “central seven”
|
A lesion of the genu of the internal capsule
|
