Skeletal muscles can indeed be named based on several criteria. Here are the relevant criteria you can select:
- Number of origins - True
- Muscle shape - True
- Type of muscle fiber - False (typically not a naming criterion)
- Direction of muscle fibers - True
- Location of muscle - True
- Relative size of muscle - True
- How much actin and myosin they contain - False (not a standard naming criterion)
So, the True statements for naming skeletal muscles would be: number of origins, muscle shape, direction of muscle fibers, location of muscle, and relative size of muscle.
