Supply: Conveys general sensory information from the skin and mucosal surfaces of the upper lips.

Origin
The superior labial branches of the infraorbital nerve originate just distally to the infraorbital foramen where the infraorbital nerve splits into its terminal branches. Its sensory fibers have cell bodies located in the trigeminal ganglion.
Course
The superior labial branches of the infraorbital nerve run from the area of the infraorbital foramen inferiorly. They run deep to the levator labii superioris muscles and into the upper lip.
Branches
There are no named branches.
Supplied Structures
The superior labial branches of the infraorbital nerve convey general sensory information from the skin and mucosal lining of the upper lip. It is unclear if they transmit parasympathetic fibers to the labial glands of the upper lip.
