Questions: Muscles that work together to cause movement are called Multiple Choice origins antagonists prime movers insertions synergists

The answer is the last one: synergists.

Explanation for each option:

• Origins: This term refers to the fixed attachment point of a muscle, not a type of muscle interaction. Therefore, it is incorrect.

• Antagonists: These are muscles that oppose the action of another muscle. They work against the movement, not together to cause it. Thus, this option is incorrect.

• Prime movers: Also known as agonists, these are the main muscles responsible for a specific movement. While they are involved in movement, the question asks for muscles that work together, which is more accurately described by synergists. Therefore, this option is not the best choice.

• Insertions: This term refers to the movable attachment point of a muscle, not a type of muscle interaction. Hence, it is incorrect.

• Synergists: These are muscles that assist the prime movers in performing a movement. They work together to enhance the movement, making this the correct answer.

In summary, muscles that work together to cause movement are called synergists.
