What is Bone and Skeleton Articulation?
The connection between two or more bones in the body is known as bone articulation or skeletal articulation. These connections provide support, mobility, and protection for the skeletal system. There are various types of bone articulations, each with its unique structure and function.
Types of Bone Articulations:
- Fibrous joints: These joints are connected by fibrous tissue, allowing limited movement. Examples include the sutures between skull bones and the syndesmoses between forearm bones.
- Cartilaginous joints: Cartilage connects bones in these joints, providing flexibility and shock absorption. Two main types are:
- Synchondroses: Temporary joints found in growing individuals, where cartilage is replaced by bone during maturation.
- Symphyses: Found in adult bones, such as the intervertebral discs.
- Synovial joints: These are the most common and movable type of joint. They have a joint cavity filled with synovial fluid, which reduces friction and allows for smooth movement.
Functions of Bone Articulations:
- Support: Articulations stabilize the skeleton and prevent bones from dislocating.
- Mobility: Certain articulations allow for a wide range of movements, such as the ball-and-socket joint in the shoulder.
- Protection: Articulations help protect bones from damage and wear by providing shock absorption and limiting excessive movement.
