Muscles are in pairs called "antagonistic muscles." Let's take the human elbow joint as an example from the diagram. The elbow joint has 2 muscles; triceps and biceps. These 2 muscles help raise your forearm up or down. In the diagram, it shows an arrow going up which represents that your forearm is being raised.
