Muscle floor of mouth. The floor of mouth is a u shaped space which extends and includes from the oral cavity mucosa superiorly and the mylohyoid muscle sling 2 3. Together the paired mylohyoid muscles form a muscular floor for the oral cavity of the mouth. This is a table of skeletal muscles of the human anatomy. Almost every muscle constitutes one part of a pair of identical bilateral muscles found on both sides resulting in approximately 320 pairs of muscles as presented in this article.
