Detailed explanation-1: -Finally, the facial nerve pierces the parotid gland (but does not innervate it) and bifurcates into superior (temporofacial) and inferior (cervicofacial) trunks, which further give rise to its five terminal branches: Temporal branches: supply the frontalis, orbicularis oculi and corrugator supercilii muscles.

Detailed explanation-2: -The temporal branch is the superior branch of the facial nerve. The nerve provides motor innervation to the frontalis muscle, corrugators, procerus and occasionally portions of the orbicularis oculi.

Detailed explanation-3: -Function. The deep temporal nerves provide motor innervation to the temporalis, which is a muscle of mastication that elevates and retracts the mandible. The deep temporal nerves also have articular branches which provide a minor contribution to the innervation of the temporomandibular joint.
