Study Notes
Facial Muscles
-
Frontalis: Responsible for raising the eyebrows and wrinkling the forehead.
-
Orbicularis Oculi: Closes the eyelids and drains tears through the tear drainage system, which includes the punctum, canaliculi, and lacrimal sac.
-
Zygomaticus: Elevates the corners of the mouth during smiles, contributing to facial expressions of happiness.
-
Buccinator: Keeps food positioned between the teeth while chewing; also aids in sucking in the cheeks.
-
Orbicularis Oris: Known as the "kissing muscle," it is responsible for lip closure and puckering.
-
Platysma: Moves the lower lip and mouth corners sideways and downwards, often changing facial expression; also depresses and wrinkles neck skin and assists in mandible lowering.
-
Cranial Aponeurosis: A fibrous tissue covering the upper part of the cranium in humans and other animals, providing structural support.
-
Temporalis: A synergist muscle that assists in the closure of the jaw during chewing.
-
Occipitalis: Moves the scalp backward, contributing to various head movements.
-
Masseter: A crucial muscle for chewing solid foods, enabling powerful jaw movements.
-
Sternocleidomastoid: Rotates the head to the opposite side; when both sides contract, it flexes the neck and extends the head.
-
