Right anterior quadrant of the scalp is supplied by the following arteries EXCEPT
**Core Concept**
The scalp is divided into four quadrants: right and left anterior, and right and left posterior. Each quadrant is supplied by specific arteries that provide blood flow to the scalp. Understanding the arterial supply of the scalp is crucial for diagnosing and managing scalp injuries, infections, and other conditions.
**Why the Correct Answer is Right**
The right anterior quadrant of the scalp is primarily supplied by the right superficial temporal artery and the right supraorbital artery. The right superficial temporal artery arises from the external carotid artery and supplies the anterior part of the scalp, while the right supraorbital artery, a branch of the ophthalmic artery, supplies the forehead and the upper eyelid. The right supratrochlear artery, another branch of the ophthalmic artery, also contributes to the blood supply of the anterior quadrant. In contrast, the right maxillary artery primarily supplies the mid-face region, including the nose, palate, and upper teeth, and does not contribute to the blood supply of the anterior quadrant of the scalp.
**Why Each Wrong Option is Incorrect**
**Option A:** The right supraorbital artery is a correct contributor to the blood supply of the right anterior quadrant of the scalp.
**Option B:** The right supratrochlear artery is also a correct contributor to the blood supply of the right anterior quadrant of the scalp.
**Option C:** The right superficial temporal artery is the primary supplier of the right anterior quadrant of the scalp.
**Clinical Pearl / High-Yield Fact**
In cases of scalp injuries or infections, it is essential to identify the arteries involved in the blood supply of the affected area to determine the best course of treatment and prevent complications.
**✓ Correct Answer: D. Right maxillary artery**
