FIBROUS****Syndesmoses****
*Bones connected by dense irregular connective tissue(usually as ligaments)
*SYNDESMO-LIGAMENT
*movement varies from immovable(synarthrotic) to slightly movable(amphiarthrotic)
*EX: synarthrotic distal tibiofibular joint (by ankle)
FIBROUS--SYNDESMOSES--Gomphoses
An example of SYNDESMOSES Peg-in-Socket joints of teeth in alveolar sockets
Fibrous connection is the periodontal ligament
