lo 5.2. what is the function of muscle insertions?
stabilize the body during movement
prevent the accumulation of lactic acid in muscles
create the force necessary for muscle contraction
provide stability to the joints
allow for movement of the body

Explanation:

Muscle insertions are the points where muscles attach to bones. When muscles contract, they pull on these insertions, which allows for movement of the body. Stabilizing the body during movement is more related to overall muscle - tendon - joint interactions and not specifically the function of insertions. Preventing lactic acid accumulation is related to metabolism and blood flow in muscles. Creating the force for muscle contraction occurs within the muscle fibers themselves. Providing stability to joints is a function of ligaments and some muscle - tendon interactions but not the main function of muscle insertions.

Answer:

Allow for movement of the body
