What type of joints are primarily found in the skull?

The joints primarily found in the skull are fibrous joints, which are known for their sutural connections. These joints are characterized by tightly bound connective tissue that provides stability and protection to the brain and cranial structures. In adults, these fibrous joints have very little movement, effectively forming a solid structure that protects vital parts of the body, including the brain.

The sutures, which are a specific type of fibrous joint, interlock the bones of the skull. This interlocking design not only enhances stability but also allows for minimal movement during the growth phases of infancy and early childhood, accommodating the growth of the brain.

The other types of joints mentioned, such as cartilaginous joints, synovial joints, and ball-and-socket joints, do exist in the body but are not the primary joint type that constitutes the majority of the skull's anatomy. For instance, cartilaginous joints allow for slightly more movement than fibrous joints and are typically found in areas such as the spine and the pubic symphysis. Synovial joints are characterized by a fluid-filled capsule that permits a wide range of movement, which is not a feature of skull joints. Ball-and-socket joints, like the hip and shoulder, facilitate
