Origin

The palpebral branches of the infraorbital nerve form distal to the infraorbital foramen, where the infraorbital nerve ends in its terminal branches. Its sensory fibers have cell bodies located in the trigeminal ganglion.

Course

From its origin just distal to the infraorbital foramen, the palpebral branches of the infraorbital nerve ascend on the maxilla, deep to the fibers of the orbicularis oculi muscle. They reach the lower eyelid and spread to both the external and internal surfaces.

Branches

There are no named branches.

Supplied Structures

The palpebral branches of the infraorbital nerve are sensory nerves. They convey general sense information from the skin and conjunctiva of the lower eyelid.
