How many ribs are present in the typical adult skeleton?

12 pair or 24 ribs

20

What term is used to identify the study of ligaments?

syndesmology

21

What are the three histological classifications of joints?

fibrous, cartilaginous and synovial fluid

22

What are the characteristics of the (amphiarthrosis) synchondrosis?

they are primary cartilage joints, temporary in longevity, composed of hyaline cartilage and form between ossification centers within a cartilage template

23

What are examples of a permanent (amphiarthosis) synchondrosis?

costochondral joints or the first sternochondral joint

Which example of a (amphiarthrosis) symphysis is temporary?

symphysis menti

25

What are the characteristics of a (amphiarthrosis) symphysis?

limited motion, median plane location, support ligaments both anterior and posterior to the joint, more permanent in longevity than synchondrosis and they occur between bones developing by endochondral ossification
