Muscles of facial expression (English)
The largest group consisting of 11 muscles is the buccolabial group. The majority… of the mouth muscles are connected by a fibromuscular hub (modiolus) at each angle of the mouth into which these muscles insert. This group is in charge of the shape and movements of the mouth and lips. The next group is the nasal group that consists of 2 muscles (nasalis and procerus muscles). Next, the orbital group consists of 3 muscles (orbicularis oculi, corrugator supercilii, depressor supercilii muscles) that are responsible for opening and closing the eyes and moving the eyebrows. The auricular group is a group of 3 fan-shaped muscles (auricularis anterior, auricularis posterior and auricularis superior muscles) that move the ear lobe/auricle to a small extent. The last group is the epicranial group (scalp and neck group) which includes 2 wide and flat muscles (occipitofrontalis and platysma muscles). The occipitofrontalis muscle consists of two bellies (occipital and frontal) and acts mainly on the forehead, while the platysma mainly acts on the neck and lower lip.
