What are ligaments?
They attach bone to bone
What are tendons/
They attach muscles to bone
What affect does strengthening muscles have on bones?
Bones can be moved by strengthening muscles
What are they type I muscles fibers?
Slow twitch/local - slow tempo, low resistance and endurance. (Long distance runners, swimmers, cyclists)
What are the type II muscles fibers?
Fast twitch/global - fast tempo, high resistance. (Sprinters, power lifting)

Body is divided symmetrically into upper and lower halves (Saw, spine twist)
What is flexion?
Movement in sagittal pane that decreases joint angle and brings two bones closer together
What is extension?
Opposite of flexion; movement increasing the angle of the distance between two bones or body parts
