Example Question #71 :Tissues, Organs, And Organ Systems
What is the name of a muscle that assists another muscle by stabilizing or positioning the surrounding bones?
Possible Answers:
Antagonist
Tendon
Agonist
Synergist
Correct answer:
Synergist
Explanation:
在肌肉收缩,肌肉认为gonist will contract while the antagonist will stretch. The agonist will cause the primary action and the antagonist would cause an opposite action. Synergists assist the agonist by stabilizing the origin bone, which facilitates movements and posture.
For example, the biceps brachii (agonist) is used to flex the arm, while the triceps brachii (antagonist) is used to straighten the arm. The brachialis is also used to flex the arm, but in a different way, making it a synergist to the biceps brachii.
Tendons are separate from muscle, and are used to secure a muscle attachment to bone.
