- What are the facial muscles and what is their function?Answered by verified global health professionalsFacial muscles, primarily controlled by the facial nerve (cranial nerve VII), are crucial for expressing emotions and performing various functions. The frontalis muscle, located on the forehead, raises the eyebrows and wrinkles the forehead, while the orbicularis oculi, surrounding the eyes, facilitates blinking and expressions like winking. The zygomaticus major and zygomaticus minor, extending from the cheekbone to the mouth, elevate the corners of the mouth, contributing to smiling. The buccinator, situated in the cheeks, compresses the cheeks against the teeth, aiding in chewing and blowing. The orbicularis oris encircles the mouth, closing and protruding the lips for actions like kissing and speaking. The depressor anguli oris lowers the mouth's corners, creating a frown, while the depressor labii inferioris and mentalis, located in the lower lip and chin, respectively, contribute to expressions of doubt or sadness. The platysma, stretching from the chest and shoulder area to the jawline, tenses the neck skin and can lower the mandible, reflecting surprise or horror. Together, these muscles enable a wide range of facial expressions, essential for non-verbal communication and social interaction.Read moreDr. Arshad Arfin2 years exp · India · General physician
