What artery supplies the basal ganglia?

What artery supplies the basal ganglia?

The blood supply to the basal ganglia comes primarily from the middle cerebral artery (#4796), in particular, the lenticulostriate branches, seen on a postmortem frontal angiogram in #9811, and as small holes in a gross horizontal specimen in #5631.

Which artery gives perforating branches?

THE PERFORATING (central, lenticulostriate) ves- sels are branches of the proximal part of the middle cerebral artery .

What does perforating artery mean?

n. An artery with its origin in the deep artery of the thigh, with distribution as three or four vessels that pass through the great adductor muscle to the posterior and lateral parts of the thigh.

What are the symptoms of infarction in the territory of left lenticulostriate artery?

The clinical aspects of lenticulostriate infarction should be properly differentiated from those of other anterior circulation infarcts. Clinical signs include motor deficit, sensory deficit and cognitive dysfunction. The principal mechanism for lenticulostriate infarction seems to be an embolism of cardiac origin.

What happens if basal ganglia is damaged?

Damage to the basal ganglia cells may cause problems controlling speech, movement, and posture. This combination of symptoms is called parkinsonism. A person with basal ganglia dysfunction may have difficulty starting, stopping, or sustaining movement.

What is the main function of the basal ganglia?

The “basal ganglia” refers to a group of subcortical nuclei responsible primarily for motor control, as well as other roles such as motor learning, executive functions and behaviors, and emotions.

What does the deep artery of thigh supply?

The main function of the deep femoral artery is to provide blood supply to the skin of the medial thigh region, proximal femur and muscles that extend, flex and adduct the thigh.

What artery supplies the posterior thigh?

The deep femoral artery supplies the posterior compartment.

What do the perforating arteries supply?

The perforating arteries (latin: arteriae perforantes) are usually three in number and arise from the deep femoral artery. All perforating arteries together provide blood supply to the posterior muscle group of the thigh and partly to the medial muscle group of the thigh.

How many perforating arteries are there?

Anatomical terminology The perforating arteries, usually three in number, are so named because they perforate the tendon of the Adductor magnus to reach the back of the thigh. They pass backward close to the linea aspera of the femur under cover of small tendinous arches in the muscle.

What does Lenticulostriate mean?

Adjective. lenticulostriate (not comparable) (anatomy) Relating to the lentiform nucleus and the striatum quotations ▼ (anatomy) Relating to the lenticulostriate arteries (a group of small arteries arising at the commencement of the middle cerebral artery) or the territory supplied by those arteries.

Where do lenticulostriate arteries arise from?

The lenticulostriate arteries, also known as anterolateral central arteries, are a collection of small perforating arteries arising from the anterior part of the circle of Willis and supplying the basal ganglia.
