The 7th cranial nerve, responsible for facial expressions, taste, and saliva production.

The larger root of the Facial nerve, responsible for movement of facial muscles.

The smaller root of the Facial nerve, carrying sensory and parasympathetic information.

Facial nerve's path within the skull.

Facial nerve's path outside the skull, to the face and neck.

Muscles controlled by the motor root of the Facial nerve, enabling facial expressions.

Sensory function of the Facial nerve, transmitting taste information from the front two-thirds of the tongue.

Branch of facial nerve carrying taste and salivary gland signals.

Facial nerve's parasympathetic function controlling salivary glands.

Canal through which the facial nerve passes.

Part of the facial nerve located within the skull.

Passage within the skull that the facial nerve travels through.

Greater petrosal, nerve to stapedius, and chorda tympani, are the 3 branches before exiting the facial canal.

Parasympathetic nerve, innervates nose, sinuses, palate, and tear glands.

Motor nerve that controls middle ear muscle that dampens sound.

Special sensory and parasympathetic nerve, taste from anterior 2/3 of tongue and salivary glands.

Part of the facial nerve located outside the skull.

Opening in the skull where the facial nerve exits.

Motor nerve that supplies muscles of the outer ear.

Temporal, zygomatic, buccal, mandibular, and cervical, are the 5 branches that extend to the face and supply motor function to facial muscles.

Elevates the hyoid bone.

5 terminal branches within the parotid gland, controlling facial expressions

Each facial branch provides motor function to specific facial muscles.

Supplies muscles in the forehead and upper eyelid.

Supplies muscles around the eyes and upper lip.

Supplies muscles of the mouth and cheeks.

Supplies muscles of the lower lip and chin.

Supplies the platysma muscle of the neck.

Moves and shapes the skin of the neck.

The nerve splits into multiple branches to control unique and diverse facial muscles.

Damage to the facial nerve before it exits the skull (stylomastoid foramen).

Damage to the facial nerve after it exits the skull (stylomastoid foramen).

Facial paralysis of unknown cause.

Facial nerve components affecting different parts of the face, possibly causing various symptoms.

Sets of muscles controlling facial movements.

Common cause for intracranial facial nerve lesion

Reduced or absent ability to taste , anterior two thirds is typically affected

Decreased tear production in the eyes.

Diminished saliva production.

Issues affecting the salivary gland, like tumors, inflammation, or surgery.
