Medial aspect of great toe supplied by
**Core Concept**
The medial aspect of the great toe is supplied by a specific branch of the dorsal pedal artery, which is crucial for sensation and proprioception in this region.
**Why the Correct Answer is Right**
The medial aspect of the great toe is primarily supplied by the medial dorsal digital artery, a branch of the dorsal pedal artery. This artery provides blood supply to the medial aspect of the toe, including the skin and the surrounding tissues. The medial dorsal digital artery is a small but vital branch that arises from the dorsal pedal artery and runs along the medial aspect of the great toe.
**Why Each Wrong Option is Incorrect**
**Option A:** The lateral dorsal digital artery, a branch of the dorsal pedal artery, primarily supplies the lateral aspect of the great toe, not the medial aspect.
**Option B:** The plantar digital arteries, branches of the plantar arch, primarily supply the plantar surface of the toes, not the dorsal surface.
**Option C:** The dorsalis pedis artery, a major branch of the anterior tibial artery, primarily supplies the dorsal surface of the foot, but its branches do not directly supply the medial aspect of the great toe.
**Clinical Pearl / High-Yield Fact**
The medial dorsal digital artery is a common site for digital artery aneurysms, which can be a complication of trauma or atherosclerosis. It's essential to recognize the vascular anatomy of the foot to diagnose and manage such conditions accurately.
**Correct Answer:** A. Medial dorsal digital artery.
