Aerial supply to putamen includes all except
**Core Concept**
The putamen is a part of the basal ganglia, and its aerial supply is crucial for the proper functioning of motor control. The putamen receives blood supply from branches of the middle cerebral artery (MCA) and the anterior cerebral artery (ACA).
**Why the Correct Answer is Right**
The putamen primarily receives its blood supply from the lenticulostriate arteries, which are branches of the middle cerebral artery (MCA). These arteries penetrate the basal ganglia and provide a rich supply of blood to the putamen, caudate nucleus, and other surrounding structures. The anterior cerebral artery (ACA) also provides some contribution to the putamen's blood supply through its anterior choroidal artery, but it is not the primary source.
**Why Each Wrong Option is Incorrect**
* **Option A:** (assuming this is the correct answer, but it's not provided) - If it's not the correct answer, it would be incorrect because it doesn't match the primary aerial supply to the putamen.
* **Option B:** This could be an incorrect option if it doesn't match the aerial supply to the putamen, such as the posterior cerebral artery.
* **Option C:** Similar to Option B, this could be incorrect if it doesn't match the aerial supply to the putamen, such as the vertebral or basilar arteries.
* **Option D:** This could be incorrect if it doesn't match the aerial supply to the putamen, such as the radial or ulnar arteries.
**Clinical Pearl / High-Yield Fact**
The lenticulostriate arteries are a high-risk area for ischemic strokes due to their small caliber and deep location within the brain. This makes them susceptible to occlusion, leading to damage to the surrounding brain tissue.
**Correct Answer:** D.
