facial muscles









































the facial muscles are a group of striated skeletal muscles supplied by the facial nerve (cranial nerve vii) that, among other things, control facial expression. these muscles are also called mimetic muscles.









































section::::structure.









































the facial muscles are just under the skin (subcutaneous) muscles that control facial expression. they generally originate from the surface of the skull bone (rarely the fascia), and insert on the skin of the face. when they contract, the skin moves. these muscles also cause wrinkles at right angles to the muscles’ action line.

"accessory muscles" refers to muscles that assist, but do not play a primary role, in breathing. there is some controversy concerning which muscles may be considered accessory muscles of inhalation. however, the sternocleidomastoid and the scalene muscles (anterior, middle and posterior scalene) are typically considered accessory muscles of breathing. both assist in elevating the rib cage. the involvement of these muscles seems to depend on the degree of respiratory effort. during quiet breathing, the scalenes are consistently physically active, while the sternocleidomastoids are quiet. with an increase in the respiratory volume, sternocleidomastoids also become active. both muscles are simultaneously activated when one breathes in at the maximal flow rate.
