What is the classification of the costocentral joint?

synovial plane (diarthrosis arthrodia)

5

What attaches to the interarticular crest of the rib?

the interarticular lig

What features may be identified on the tubercle of a typical rib?

the articular surface of the tubercle and the non-articular surface of the tubercle

12

What joints with the articular surface of the tubercle of the rib?

the transverse costal facet of a thoracic transverse tubercle

13

What is the name of the joint formed by the articular surface of the tubercle and the transverse costal facet?

the costotransverse joint

14

What is the classification of the costotransverse joint?

synovial plane (diarthrosis arthrodia)

18

What features may be identified on the body of a typical rib?

- costal angle

19

What is the costal angle of a rib?

the location on the body of the rib where there is a directional change toward the sternum

20

What attaches to the costal angle of a rib?

the iliocostalis muscle and thoracolumbar aponeurosis/fascia

21

What is the costal groove of a rib?

the linear depression on the internal and inferior surface of the body

What is present at the sternal end of a rib?

costal cartilage

24

What is present on the head of the first rib?

a single articular surface

25

What is lacking at the head of the first rib?

the interarticular crest

26

Is there a crest on the neck of the first rib?

not a well-developed one like on the typical rib

27

What is unique about the body of the first rib?

the body of the first rib is flattened and has a scalene tubercle flanked by the groove for the subclavian artery and the groove for the subclavian vein

28

What attaches to the scalene tubercle of the first rib?

anterior scalene muscle

29

Which groove on the body of the first rib is close to the vertebral end?

the groove for the subclavian artery and the first thoracic nerve

30

Which groove on the body of the first rib is closer to the sternal end?

the groove for the subclavian vein
