Chapter 9. Classification of Joints

Fibrous joints are held together by dense regular connective tissue and do not have a joint cavity, while cartilaginous joints are joined by cartilage and also lack a joint cavity.

The joint cavity in synovial joints allows for greater range of motion by providing fluid lubrication, which reduces friction between articulating surfaces.

Ligaments attach bones to each other within synovial joints, providing stability while allowing for mobility.

<p>A synarthrosis is an immobile joint, characterized by dense regular connective tissue or cartilage that holds the ends of bones together without a joint cavity.</p> Signup and view all the answers

<p>A synovial joint is classified as diarthrosis because it allows for free movement, featuring a joint cavity, articular cartilage, and a synovial capsule with fluid.</p> Signup and view all the answers

<p>Cartilaginous joints are characterized by a pad of cartilage between bone ends and are categorized functionally as synarthroses or amphiarthroses, depending on their mobility.</p> Signup and view all the answers

<p>No, not all amphiarthroses are fibrous; one type is a cartilaginous joint, specifically the symphysis.</p> Signup and view all the answers
