The knee is primarily protected by the femur (thigh bone) and the tibia (shin bone), which are the main bones that form the knee joint. The patella, or kneecap, also plays a protective role in front of the knee. For the elbow, the humerus (upper arm bone) and the ulna (one of the forearm bones) are the key bones that protect the joint. The radius, another forearm bone, also contributes to the elbow's structure and stability.
Skeletal joints are where two bones come together, such as the knee is a hinge joint. Or the elbow is also a hinge joint.

There are at least two bones in a joint. The elbow joint has two bones but the knee joint has three.
Yes, the bones in your arm do cross when you bend your elbow. The ulna and radius, which are the two bones in your forearm, move in relation to each other when you bend your elbow.
bones
The bones that form the hinge joint at your elbow are the humerus, ulna, and radius. The humerus is the upper arm bone, while the ulna and radius are the two forearm bones. These bones come together to allow the elbow to bend and straighten.
There are 360 joints in the human body. Joints are where two or more bones meet and allow movement. Examples include the knee, elbow, and shoulder joints.
a knee
The area where two or more bones join together is called a joint. Joints allow for movement and provide stability to the skeletal system. Examples of joints include the knee, elbow, and shoulder.
The action of increasing the angle of a joint, thereby moving two bones farther apart, is referred to as "extension." This movement typically occurs in joints such as the elbow or knee, where straightening a flexed limb increases the angle between the bones involved. Extension is the opposite of flexion, which decreases the angle between the bones.

The left radius and ulna, the bones of the forearm, are distal to the left elbow and proximal to the left wrist. The radius is the larger of the two bones.
