Synergists are Muscles That _______

Question

Synergists are muscles that _______.
A) relax when the agonist is contracted
B) are responsible for muscle tone
C) stabilize joints
D) contract isometrically

Accepted Answer

Synergists are muscles that work together with the agonist to stabilize a joint and help produce movement. They do not necessarily relax when the agonist contracts or have a direct role in muscle tone. Isometric contraction can occur in both agonist and synergist muscles, so it is not a defining characteristic of synergists.
