articulação

An articulação, in Portuguese, refers to a joint, the point where two or more bones meet. These structures are crucial for movement, allowing for flexibility and mobility within the skeletal system. There are various types of articulações, classified by their structure and the degree of movement they permit.

Fibrous articulações, also known as fixed joints, allow for very little or no movement. Examples include the sutures of the skull. Cartilaginous articulações, or slightly movable joints, are connected by cartilage. The intervertebral discs between vertebrae are a good example. Synovial articulações are the most common and allow for a wide range of motion. These are characterized by a joint cavity filled with synovial fluid, which lubricates the joint. Examples include the knee, elbow, and shoulder joints.

The health of articulações is vital for overall physical function. Conditions such as arthritis, which involves inflammation of the joints, can significantly impair mobility and cause pain. Maintaining healthy articulações often involves regular physical activity, a balanced diet, and avoiding excessive stress on the joints. The proper functioning of these biological connections is fundamental to performing everyday activities.
