In elbow and knee joints, the bones can move in a hinge-like manner, allowing for flexion and extension. This type of movement enables the arm and leg to bend and straighten, facilitating actions such as lifting objects or walking. The range of motion is primarily limited to this forward and backward movement, providing stability while allowing functional mobility.
Joints at the knee and elbow are hinge joints, designed to move in one primary direction (flexion and extension). The structure and shape of these joints limit rotational movement to protect them from injury. Rotation at these joints is mainly performed by the muscles and bones of the forearm and leg rather than at the knee or elbow joints themselves.

Yes, articulation refers to the joints where bones meet and move together. These joints are part of the adult skeleton and facilitate movement. Examples include the knee, elbow, and shoulder joints.
A hinge joint, like the knee or elbow, allows bones to move backward in only one direction. This type of joint allows for bending and straightening movements, providing stability and control during activities like walking or weightlifting.
Try the joints: hip, knee, ankle.
Movable joints can be moved, immovable joints can not.
Joints that allow movement in a single plane are called trochlear joints, also known as hinge joints. Examples of such joints are the knee and the humero-ulnar joint of the elbow. Technically the knee does rotate slightly in the last few degrees of extension which is called the "screw home mechanism", but is still considered a hinge joint.hinge
The ribs expand so that we can breathe. When the ribs expand, the volume of the pleural space increases and the lower pressure brings in air.
Hinge joints in the body, like the elbow and knee, allow movement in one direction like a door hinge. They enable flexion and extension movements, such as bending and straightening. These movements are possible due to the structure of the bones and the ligaments that stabilize the joint.
Hinge bones are called hinge bones because they resemble hinges that are on a door. They move on one level like elbow or knee movement.
A joint is where two sections of something come together. With bones, your elbow, knee, jaw, fingers, etc. are all mobile joints, because they move. A rigid joint would be where the bones don't move; your skull has various bones that connect but do not move.
