Blood supply of great toe is
## **Core Concept**
The blood supply to the toes, including the great toe, primarily comes from branches of the **dorsalis pedis artery** and **plantar arteries**, which are derived from the **posterior tibial artery**. Understanding the arterial supply is crucial for assessing and managing vascular-related conditions in the foot.
## **Why the Correct Answer is Right**
The great toe, also known as the hallux, receives its blood supply mainly from the **dorsalis pedis artery** and its branches, specifically the **first dorsal metatarsal artery**, which then divides into the **dorsal and plantar branches** to supply the toe. Additionally, the **plantar digital arteries**, which arise from the **plantar metatarsal arteries** (branches of the **posterior tibial artery**), contribute to its supply, especially on the plantar aspect.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it does not accurately represent the primary blood supply to the great toe. Without specifics, we assume it does not correctly identify the arterial supply.
- **Option B:** Similarly, this option is incorrect as it presumably does not accurately describe the blood supply to the great toe.
- **Option C:** This option might seem plausible but is incorrect based on the correct answer provided.
## **Clinical Pearl / High-Yield Fact**
A key clinical point to remember is that the dorsalis pedis artery, located on the dorsum of the foot, is a common site for palpating the pulse and assessing peripheral arterial disease. The great toe's blood supply is critical for wound healing, especially in diabetic patients prone to foot ulcers.
