1 | Definition | Two or more muscles work together to perform the same movement. | Two muscles work in opposition to perform opposite movements. |
2 | Nature of cooperation | Muscles assist each other in the same direction of movement. | One muscle contracts while the other relaxes to produce reverse movement. |
3 | Example | Biceps and brachialis during elbow flexion. | Biceps and triceps during flexion and extension of the elbow. |
4 | Purpose | To increase strength and efficiency of movement. | To control and balance movements in opposite directions. |
5 | Movement Type | Same type of movement (e.g., both flexors or both extensors). | Opposite type of movement (e.g., flexor vs. extensor). |
