Nerve which lies in association to Wharton’s duct is-
**Core Concept**
The question requires knowledge of the anatomical relationship between nerves and salivary glands, specifically the submandibular gland and its duct, Wharton's duct. The submandibular gland is one of the major salivary glands, and its duct, Wharton's duct, opens into the oral cavity.
**Why the Correct Answer is Right**
The lingual nerve, a branch of the mandibular division of the trigeminal nerve (CN V3), runs close to Wharton's duct as it crosses the floor of the mouth. The lingual nerve provides sensory innervation to the anterior two-thirds of the tongue and is also associated with the submandibular gland. The close anatomical relationship between the lingual nerve and Wharton's duct makes the lingual nerve susceptible to injury during surgical procedures involving the submandibular gland.

**Clinical Pearl / High-Yield Fact**
The lingual nerve is at risk of injury during submandibular gland surgery, such as during a submandibular gland biopsy or removal. The nerve can be damaged during dissection, leading to numbness or altered sensation in the tongue.
