Figure 7.38 Different growth rates of body parts determine body proportions.

Sir John Charnley – doctor who pioneered the use of artificial

joints in the early 1960s.

Fibrous Joints – joints that are created via fibrous connective tissues that are going to allow virtually no movement.

(a) Suture

Joint held together with very short,interconnecting fibers, and bone edges

interlock. Found only in the skull.

(b) Syndesmosis

Joint held together by a ligament.Fibrous tissue can vary in length, but

is longer than in sutures.

(c) Gomphosis

“Peg in socket” fibrous joint. Periodontalligament holds tooth in socket.

Cartilaginous Joints – joints that are created via cartilage these joints allow a small amount of movement.
