Muscles can be divided into the following three types in terms of structure and function. They are skeletal muscles attached between bones and bones, myocardium forming the heart wall, and internal muscles forming walls such as stomach, bladder, and uterus, which are directly under the skin of the hands, feet, chest, stomach, and back. Usually, when it comes to flesh or muscles, it refers to skeletal muscle. Skeletal muscle, also known as transverse muscle, is a voluntary muscle. In addition, myocardium has a horizontal pattern, so it is a kind of horizontal patterned muscle, but it cannot move according to its will. The internal muscles are also called plain muscles, which cannot be moved according to their will. 비앤비 여성전용아로마스웨디시 마사지
