Verified step by step guidance1
Understand the terms 'origin' and 'insertion': In muscle anatomy, the 'origin' is the fixed attachment, while the 'insertion' is the movable attachment.
Recognize the process of muscle contraction: During contraction, the muscle fibers shorten, pulling the insertion towards the origin.
Evaluate the statement: 'During a muscle contraction, the origin moves towards the insertion.'
Determine the accuracy of the statement: Since the insertion moves towards the origin, the statement is false.
Identify the correct correction: The correct statement is 'False, the insertion moves towards the origin during contraction.'
