Each page under the Anatomy - KINE 2031 section (Lab 2, Lab 3 etc) will provide extra resources to help you with your studying and review of the lab material covered in this course. There are pictures of each muscle covered as well as each muscle's origin, insertion, and function.

Legend (For all Labs): O = Origin - Proximal attachment of a muscle (Closer to midline of body)

                                       I = Insertion - Distal attachment of a muscle (Further away from midline of body)

                                      F = Function/Action - The function/action of the muscle at the joint(s)/articulation(s) it is attached to
