FUNCTIONAL QUESTION. “The orbicularis-oris-muscle-complex...one of the most complex muscles in the human face.” https://lnkd.in/dy_Wee2 View in LinkedIn

SIGNALS OF EMOTION. “The orbicularis oris is a complex sphincter that functions in conjunction with the muscles of facial expression. The orbicularis oris circles around the upper and lower lips and compresses, contracts and protrudes the lips. The gamut of emotions and actions can be expressed with this sphincter muscle.” Mona Lisa lives. https://lnkd.in/dRMaFi5 View in LinkedIn

“THE NASOLABIAL FOLD varies considerably from person to person. Three main groups may be distinguished: convex, concave, and straight. It is the muscles of smiling that are directly responsible for the shape and depth of the fold, and in their absence of function, as in facial palsy, the nasolabial fold disappears.” (Laugh lines). https://lnkd.in/dGeUA-g View in LinkedIn

THE HUMAN SMILE. “Monkeys, imitators of man's gesture never shared smile with him and their facial expressions only result in grimaces. Study of animal anatomy may explain why subtle expressions of the lips are a more man's special gift than laughter.” https://lnkd.in/dg2kCaB View in LinkedIn

THE FACIAL MODIOLUS. “In facial anatomy, the modiolus is a chiasma of facial muscles held together by fibrous tissue, located lateral and slightly superior to each angle of the mouth. It is important in moving the mouth, facial expression and in dentistry.” https://lnkd.in/daNTbUH) View in LinkedIn

NUANCED CONTROL. “These fine movements are related to a subcutaneous muscular structure termed modiolus, which is the meeting point of muscles involved in the motion of mouth and comparative anatomy shows this structure to be better defined in Man than in other primates.” https://lnkd.in/dg2kCaB View in LinkedIn

CONVERGENCE. “Embryologically, muscles that form the modiolus derive from a cellular concentration in the region of the second branchial arch. It is then logical to see these muscles converge to the corner of the mouth to form the modiolus, as they emerge from a common area.” http://europepmc.org/abstract/med/10783511 View in LinkedIn

SUBTLE EXPRESSIONS. “Functioning of the modiolus is complex, as its position may change many times in a minute to allow the orbicularis oris muscle to take any position and do any movement as if it was inserted on bone. With its complex physiology, the modiolus is of critical importance in the subtle expressions of the lips and must be preserved or reconstructed when performing repair of full-thickness tissue defects of lips.” http://europepmc.org/abstract/med/10783511 View in LinkedIn

BEAUTY MUSCLES. “When well developed, the two modioli make the mouth soft and provide the lateral boundaries of its natural esthetic unit, making the inferior portion of the face quite separate from the middle one.” https://page-one.live.cf.public.springer.com/pdf/preview/10.1007/s00238-001-0333-9 View in LinkedIn

BEAUTY BONE. “A prominent cheek-bone and a well-defined modiolus provide very important aspects of beauty and youth of the inferior part of the face.” https://page-one.live.cf.public.springer.com/pdf/preview/10.1007/s00238-001-0333-9 View in LinkedIn
