Question

structural classification – what type of structural joint is found at the skull sutures? * 1 point a) synovial b) fibrous c) cartilaginous d) ball-and-socket

Explanation:

To determine the structural joint type of skull sutures, we analyze each option:

• Option a: Synovial joints are freely movable (e.g., knee, elbow) and have a synovial cavity, which skull sutures lack.
• Option b: Fibrous joints are connected by dense connective tissue (collagen fibers). Skull sutures are fibrous joints, as the bones are joined by fibrous tissue with minimal to no movement (sutures are a type of fibrous joint).
• Option c: Cartilaginous joints are joined by cartilage (e.g., intervertebral discs, pubic symphysis) and allow limited movement, unlike skull sutures.
• Option d: Ball - and - socket is a type of synovial joint (e.g., hip, shoulder) and is not related to skull sutures.

Answer:

b) Fibrous
