T9

Question 9

What costal cartilage articulates with the sternal angle?

Answer 9

The second costal cartilage

Question 10

What are the typical ribs? What shape are they?

Answer 10

3-9

Curved, flat bones

Question 11

How does the head of a rib articulate with the vertabrae?

What does the tubercle of the rib attach to?

Answer 11

The head attaches to the inferior articular facet of the number that goes above the rib and the superior facet of the number that corresponds with it - so Rib 7 attaches to the inferior facet of T6 and the superior facet of T7

The tubercle of the rib attaches to the transverse process of the same numbered vertebrae - rib 7 to T7

Question 12

What does the tubercle articulate with?

Answer 12

The transverse process

Question 13

What lies in the costal groove?

Answer 13

Intercostal nerves and vessels

Question 14

What ribs are true ribs and what does this mean?

Answer 14

1-7 attaches to the sternum directly

Question 15

What ribs are false ribs?

Answer 15

8-10 - attaches to sternum via cartilage

Question 16

What ribs are the floating ribs?

Answer 16

11-12

Question 17

View the diagram of a rib and learn the anatomy. Describe it now.

Answer 17

Starting from the head - Superior and Inferior facets - body of angle - costal groove - then site of articulation with costal cartilage

Question 18

How is the 1st rib different?

Answer 18

Only articulates T1
Different shape
Has two grooves for the subclavian artery and vein
Has a tubercle for the scalene muscle

Question 19

Anterior or posterior to the 1st rib - Sub Clavian Vein and SC artery

Answer 19

SC artery is posterior

SC vein is anterior

Question 20

Answer 20

Body - heart shaped

Spinous process is slanted

Question 21

What part of the vertabrae does the rib attach to?

Answer 21

Superior articular facet for the rib above

Inferior articular facet for the rib below

Question 22

What passes through the vertebral foreman?

Answer 22

The hole
Spinal cord
Meninges - dura - arachnoid - pia

Question 23

What lies in the inferior vertebral notch?

Answer 23

Spinal nerves

Question 24
