Articulações

Articulações, also known as joints, are the points where two or more bones meet in the skeletal system. They are essential for movement, providing flexibility and allowing the body to perform a wide range of actions. Without joints, the skeleton would be a rigid structure.

There are various types of articulações, classified based on their structure and the degree of movement they permit. Fibrous joints, like those found between the bones of the skull, are immovable. Cartilaginous joints, such as the joints between vertebrae, allow for limited movement and are connected by cartilage. Synovial joints are the most common type and are characterized by a fluid-filled cavity that lubricates the joint, allowing for a wide range of motion. Examples include the knee, elbow, and shoulder joints.

The proper functioning of articulações is crucial for overall mobility and quality of life. Conditions like arthritis and injuries can affect joints, leading to pain, stiffness, and reduced function. Maintaining healthy joints through regular exercise, a balanced diet, and proper posture is important for preventing issues and ensuring continued mobility throughout life.
