Direction of fibers or fascicles - eg. Rectus (fibers run straight), transversus and oblique (fibers run at angles to an imaginary defined axis) and ACTION (eg. flexor or extensor = muscles that flex or extend)
Location (eg. Bone or body region associated with the muscles) and number or origins (eg. biceps = 2 origins, triceps = 3 origins)
All of the above plus location of attachments (named according to point of origin or insertion)
