The facial nerve (cranial nerve VII) plays a crucial role in controlling the muscles of facial expression, including those around the eye. It innervates the orbicularis oculi muscle, which is responsible for closing the eyelids, facilitating blinking and protecting the eye. Additionally, the facial nerve contributes to tear production by stimulating the lacrimal glands through its parasympathetic fibers. Dysfunction of the facial nerve can lead to problems such as dry eyes or inability to close the eyelids properly.

Which nerve affects your sense of taste and facial expressions?
The facial nerve (cranial nerve VII) affects your sense of taste for the anterior two-thirds of the tongue and is responsible for controlling facial expressions through its motor functions.
Which one of the following nerves serves the anterior tongue's?
The chorda tympani nerve, a branch of the facial nerve, serves the anterior two-thirds of the tongue for taste sensation.
Taste fibers to anterior two thirds of the tongue are carried by?
the Chorda Tympani nerve ( a branch of the facial nerve VII) which joins the lingual nerve medial to the lateral pterygoid muscle.
Which cranial nerve is involved in the secretion of saliva?
CN VII (facial) The cranial nerves that regulate salivation are CN VII (facial) and CN IX (Glossopharyngeal). The cranial nerves that transmit the special sense of taste are CN VII (facial, to the anterior 2/3rd of the tongue) and CN X (vagus, to the posterior 1/3rd of the tongue). Of these nerves, only CN VII (facial) transmits both taste and salivation control.
