So these are also the functions of facial nerve: Somatic sensory Special sensory Branchial motor Parasympathetic motor To remember the branches of the facial nerve, you can use the following mnemonic: "To Zambia By Motor Car", standing for: Temporal Zygomatic Buccal Marginal mandibular Cervical branches.
