15) Explain the guidelines used in naming skeletal
muscles, such as location, size, direction, etc.
Develop a graphic that identifies the name of the muscle,
the directional motion, location, and function of the
following muscle groups:

Objective
Explain the methods used in naming the
skeletal muscles by “creating” a muscle
with a given name and function.

3 – Size of the muscle
4 – Direction/Orientation of the muscle
fibers/cells
5 – Number of Origins
6 – Location of the Attachments
7 – Action of the muscle

Create a Muscle!!!
With a partner, use the methods in naming
muscles to create your OWN muscle!
Decide its location and function.
Give your muscle a name based on the
given standards we discussed.
Use the correct terminology in describing
its movement and function.
BE CREATIVE!!!
We will share our ideas with the class.

Individual Activity
Work on Crossword Puzzle!!!
Make sure to have an Answer Key with the
crossword filled in.
Make sure to have a blank crossword, so
we can switch with each other this week.
