Fibrous and Cartilaginous Joints - Lab Practical 3

Fibrous joints

The bones are joined by fibrous tissue, no joint cavity is present. Movement depends on length of fibers, most are synarthrotic.

Sutures

Fibrous joint. The irregular edges of the bones interlock and are united by very short connective tissue fivers. Ex: most joints of the skull.

Syndesmoses

Fibrous joint. The articulating bones are connected by short ligaments of dense fibrous tissue; the bones do not interlock. Allows some gives, though classified as a synarthrosis. Ex: distal end joint of tibia and fibula.

Synarthrosis

An immovably fixed joint between bones connected by fibrous tissue.

Gomphosis

Fibrous joint. joint in which a tooth is secured in a bony socket by the periodontal ligament.

Cartilaginous joints

The articulating bone ends are connected by a plate or pad of cartilage. No joint cavity is present. Most are amphiarthrotic.

Amphiarthrotic

joints that are slightly movable.

Symphyses

Cartilaginous joint. Bones are connected by a broad, flat disc of fibrocartilage. Ex: intervertebral joints between adjacent vertebral bodies and the pubic symphysis of the pelvis.

Synchondroses

Cartilaginous joint. The bony portions are united by hyaline cartilage. Ex: epiphyseal plates in the long bones of growing children.
