Question

What major muscles cause frowning, smiling, and pouting?

Answer 1

Hint: A frown (also referred to as a scowl) may be a countenance or can be called a reaction where the eyebrows are brought along, and therefore the forehead is wrinkled. A smile is created primarily by flexing the muscles at the edges of the mouth. Pouting, a contraction of the muscles within the lips.

Complete answer: Frowning sometimes indicates dissatisfaction, unhappiness or worry, or less typically confusion or concentration. Corrugator Supercilii and Procerus muscles are placed wherever the highest nose meets the forehead and are to be blamed for the expression of displeasure and pouting.
-Zygomaticus major and minor –These muscles pull up the corners of your mouth and are to be blamed for smiling.
-Zygomaticus major (2 muscles), Orbicularis oculi (2 muscles), Levator labii superioris (2 muscles, Levator anguli oris (2 muscles), Risorius (2 muscles), Zygomaticus minor (2 muscles) in total twelve muscles are used for smiling.
-Platysma (2 muscles), Orbicularis oculi (2 muscles), Corrugator supercilii (2 muscles), Procerus (1 muscle), Orbicularis oris (1 muscle), Mentalis (1 muscle), Depressor anguli oris (2 muscles therefore in total eleven muscles are used for expressing displeasure.
-In conjunction with orbicularis contraction, the mentalis muscle permits the lips to "pout". Externally, mentalis contraction causes wrinkling of the chin skin, as employed in expressions of doubt or dissatisfaction. It’s typically observed because of the "pouting muscle".

Note: The muscles are responsible for carrying out a number of functions.The muscular structure consists of muscle tissue. There are about 639 separate muscles in our body (approx). This tissue consists of long, narrow and they are extremely specialized cells which are referred to as muscle fibers.
