Which of the following best describes the causes of common forms of arthritis? -
ANSWERSRheumatoid arthritis is an autoimmune disease and osteoarthritis is caused
by effects of aging.
Classifying joints as synarthrotic, amphiarthrotic, or diarthrotic represents -
ANSWERSthe degree of movement possible at the joint.
Which of the following does not describe the function(s) of the skeletal system? -
ANSWERSIt generates the movements of the limbs.
Choose the correct statement about muscle contraction. - ANSWERSActin filaments

in relation to bones. In what body region would you expect the frontalis muscle to
originate? - ANSWERSthe cranium

many different muscle fibers in a group. Choose the statement that correctly explains
how this affects muscle contraction. - ANSWERSA signal traveling through one motor
neuron can potentially make multiple fibers in a group contract, generating more force.
