Which of the following nerves does NOT provide secretomotor innervation to the submandibular gland?

Explanation

The facial nerve, specifically through its branch the chorda tympani, along with the lingual nerve, contribute to the secretomotor supply of the submandibular gland. However, the mylohyoid nerve is primarily a motor nerve to the mylohyoid muscle and does not provide secretomotor innervation to the gland.
