What is the difference between muscle flexing and extension?

Muscle flexing and extension are two opposing movements of a joint. Flexion is the bending of a joint, while extension is the straightening of a joint.

Here are some examples of muscle flexing and extension:

* Flexing your arm at the elbow is called elbow flexion.

* Extending your arm at the elbow is called elbow extension.

* Flexing your knee is called knee flexion.

* Extending your knee is called knee extension.

Muscle flexing and extension are both important for movement. They allow us to move our limbs in different directions and to perform a variety of tasks.

Here are some of the muscles responsible for flexing and extending different joints:

* Biceps brachii: Flexes the elbow

* Triceps brachii: Extends the elbow

* Quadriceps femoris: Extends the knee

* Hamstrings: Flex the knee

The strength of our muscles and the range of motion of our joints are important factors in our ability to perform everyday tasks. Muscle weakness or joint stiffness can make it difficult to move and perform daily activities.
