No, the elbow is not a small joint. It is a complex hinge joint that allows for bending and straightening of the arm, as well as some rotational movement.
The cubital joint is an example of a hinge joint. This type of joint allows movement in one plane, like bending and straightening, similar to how the elbow functions.
The knuckle joint allows for flexion and extension movements, so bending and straightening the joint. It does not allow for lateral or side-to-side movement.
An example of extension movement is straightening the arm at the elbow joint, which occurs when you move your forearm away from your upper arm. This action increases the angle at the joint, allowing for a wider range of motion. Other examples include straightening the leg at the knee or extending the spine during a backbend.
The knee joint is located in the leg at the knee. It is a type of hinge joint.
Extension in medical term means the action of stretching part of your body.
Straightening out a limb involves extending it so that it is in a linear or straight position, typically increasing the angle between the limb and the joint. This movement is controlled by the muscles and tendons surrounding the joint.

The cubital joint is an example of a hinge joint. This type of joint allows movement in one plane, like bending and straightening, similar to how the elbow functions.
The straightening of a joint so that the angle between bones increases is known as extension. This movement typically occurs in hinge joints, such as the elbow and knee, where the limb straightens out. Extension is the opposite of flexion, which decreases the angle between the bones at a joint.
straight ;eg
Straightening the hip joint is referred to as extending the hip joint (iliofemoral joint). There are several muscles that do this, mainly the gluteus maxiumus.
Hyperextension - Is a straightening movement that goes beyond the normal, healthy boundaries of ones joint.
In addition to simple flexion (bending) and extension (straightening) movements, the knee joint is designed to allow for rotation, gliding, and rolling movements.
The knuckle joint allows for flexion and extension movements, so bending and straightening the joint. It does not allow for lateral or side-to-side movement.
The opposite action of flexion is extension. While flexion involves decreasing the angle between two body parts, such as bending a joint, extension involves increasing that angle, effectively straightening the joint. For example, bending the elbow is flexion, while straightening it is extension.
Yes, extension is always in the opposite direction as flexion. Hyperextension means straightening a joint beyond it's normal range.
