What is a Monoarticular muscle?
Muscle–tendon units (MTUs) in animal limbs can be categorized as monoarticular if they cross one joint, biarticular if they cross two joints, and multiarticular if they cross three or more joints. Monoarticular muscle tendon units must lengthen or shorten with the flexion or extension of the joint they cross.
What is the difference between multi joint and single joint exercises?
Single joint exercises use one joint to perform the range of motion. You may also know them as isolating exercises as they focus in on one muscle group. Multi-joint exercises use more than one joint and several muscle groups to support throughout the full range of motion.
What are three multi joint exercises?

Is the brachialis monoarticular or polyarticular?
> The brachialis is monoarticular, because it attaches to the forearm and the humerus (arm bone): It only covers a single joint. > The biceps is polyarticular, because it attaches to the shoulder and the forearm (not to the humerus): It covers two joints.
