(A) The diagram illustrates the way to determine the start and the end point of overlap between the submandibular duct and the lingual nerve. (B) The start of the overlap (a); the end of overlap (b); LN: lingual nerve; SMD: submandibular duct.

The diagram illustrates the measuring of the extent of overlap between the lingual nerve and the submandibular duct (distance a-b).
Fig 6.
The four different patterns of the lingual nerve endings at the ventral surface of the tongue (a) Only one lingual nerve at the terminal end; (b) Two branches were found at the terminal end; (c) Three branches were found at the terminal end; (d) Four branches or more were found at the terminal end.
