## **Core Concept**
Little's area, also known as Kiesselbach's plexus, is a vascular network located in the anterior part of the nasal septum. It is a common site for nasal bleeds (epistaxis) due to its rich blood supply and exposed location. The area is supplied by branches from several arteries.

## **Why the Correct Answer is Right**
The arteries that typically contribute to Little's area are:
- Sphenopalatine artery (a branch of the maxillary artery)
- Anterior ethmoidal artery (a branch of the ophthalmic artery)
- Greater palatine artery (a branch of the maxillary artery)
- Septal branch of the superior labial artery (a branch of the facial artery)

The **Septal branch of the superior labial artery** is one of the main contributors to Little's area, along with the other mentioned arteries.

## **Why Each Wrong Option is Incorrect**
- **Option A:** The sphenopalatine artery is a primary contributor to Little's area, providing significant blood supply.
- **Option B:** The anterior ethmoidal artery also contributes to the vascular supply of Little's area.
- **Option C:** The greater palatine artery is another artery that supplies blood to this region.

## **Clinical Pearl / High-Yield Fact**
A key clinical point to remember is that Little's area is a common site for epistaxis due to its rich vascular supply from multiple arteries, making it prone to bleeding. The arteries involved create a plexus that is easily damaged.

## **Correct Answer:** D. Posterior ethmoidal artery.
