Dorsal muscles of the head and trunk include the serratus  posterior, the serratus posterior superior, the splenius capitis,  the spinalis, the latissimus dorsi, the multifi â¦ dus, and the  sphincter ani internus.
Muscles consist of a fleshy belly which is usually attached to bone at each end by a region of dense connective tissue. In most cases this connective tissue forms a cord-like structure called a tendon. In large, flat muscles the tendon is often a flattened sheet called an aponeurosis.he end of a muscle furthest from the dorsal midline, more distal or more movable is called the insertion. As the muscles are described, the origin and insertion will be identified; try not to simply memorize which is which.
