Structure superficial to mylohyoid in anterior digastric triangle are all EXCEPT:
**Core Concept**
The anterior digastric triangle is an anatomical region in the neck, bounded by the anterior belly of the digastric muscle, the mandible, and the mylohyoid muscle. The structures superficial to the mylohyoid muscle in this region are of clinical importance for various surgical and anatomical procedures.
**Why the Correct Answer is Right**
The correct answer is based on the anatomical organization of the neck and the specific relationships between the mylohyoid muscle and the surrounding structures. The mylohyoid muscle is a muscular diaphragm that separates the submandibular and sublingual spaces from the submental and submaxillary spaces.
**Why Each Wrong Option is Incorrect**
**Option A:** The correct answer is not provided, so we will assume it as "A. Mylohyoid muscle" (which is incorrect, as it is the structure in question).
- The mylohyoid muscle itself is the structure in question, so it is not superficial to it.
**Option B:**
- The submandibular gland is located deep to the mylohyoid muscle, not superficial to it.
**Option C:**
- The submental lymph nodes are located superficial to the mylohyoid muscle, making this option incorrect.
**Option D:**
- The facial artery is located superficial to the mylohyoid muscle, making this option incorrect.
**Clinical Pearl / High-Yield Fact**
In the anterior digastric triangle, the facial artery and vein are located superficial to the mylohyoid muscle, and the submandibular gland is located deep to the muscle. This anatomical relationship is crucial for surgical procedures in the neck.
**Correct Answer: C. Submandibular gland.**
