This document describes various characteristics of muscles including their location between ribs or along bones, their fiber direction as straight, crossed, or slanted, their actions such as flexing, extending, or drawing together, their shapes like triangular or long/short, their sizes as largest or smallest, the number of attachment points of origin, and specific points of attachment including the mastoid process or styloid process. Key muscles mentioned are the intercostal, rectus, transverse, oblique, deltoid, maximus, and styloglossus.
