A&P Lab Exam 2

Fibrous Joint

Structural Characteristics: Adjoining bones connected by dense fibrous connective tissue; no joint cavity Examples: -Squamous suture between the parietal and temporal bones-synarthrosis (immovable) -Between the tibia and fibula- amphiarthrosis (slightly movable and immovable) -Tooth in a bony socket- synarthrosis

Cartilaginous joint

Structural Characteristics: Adjoining bones united by cartialge; no joint cavity Examples: -Between the costal cartilage of rib 1 and the sternum and the epiphyseal plate in growing long bones- synarthrosis -Intervertebral discs between the adjacent vertebrae and the anterior connection between the pubic bones- amphiarthrosis

Synovial joint

Structural Characteristics: Adjoining bones covered in articular cartilage; separated by a joint cavity and enclosed in an articular capsule lined with synovial membrane Examples (all diarthrosis [freely movable]): -Between the carpals of the wrist -Elbow joint -Proximal radioulnar joint -Between the metacarpals and the proximal phalanx -Between the trapezium (carpal) and metatarsal I -Shoulder joint
