Detailed explanation-1: -The posterior auricular nerve is the first extracranial branch to emerge which continues to provide motor innervation to the occipital belly of the occipitofrontalis muscle (occipital branch) and intrinsic auricular muscles (auricular branch).
Detailed explanation-2: -The principal muscles are the frontalis, orbicularis oculi, buccinator, orbicularis oris, platysma, the posterior belly of the digastric, and the stapedius muscle.
Detailed explanation-3: -The labyrinthine segment gives off three branches: the greater superficial petrosal nerve (containing parasympathetic fibers for the lacrimal gland and taste fibers from the palate), the lesser petrosal nerve, and the external petrosal nerve. The fourth segment of the facial nerve is the tympanic segment.
