Part 2: Naming of the Muscles

Muscle Lab Guide: Checklist of muscles you need to know for the exam

How Muscles are Named - short explanation of where these weird names come from

Muscles Coloring: Major groups represented, color and learn!

*As you progress through each body section below, label the corresponding images to help you learn the muscle names. Always refer back to your lab guide to determine which muscles will be on the final lab test. Coloring the muscles as you label may also be a way to remember the names.

Each of the following sections has a blank sheet for printing that can be labeled by looking at the images of that section.

Label the Head and Neck
