Answer 3

floating
don’t attach to the sternum

Question 4

sternum

Answer 4

mannibrum
body
xiphoid process

Question 5

thoracic inlet

Answer 5

superior opening

boarders- anterior mannibruim
lateral- 1st ribs/ costal cart
posterior- t1 vert

Question 6

thoracic outlet

Answer 6

inferior opening

xipisternum joint- costal margin
2 floating ribs
t12 vert

closed off by thoracic diaphragm

Question 7

manubriosternum joint

Answer 7

secondary cartilaginous
angled
slightly mobile

Question 8

xiphisternum joint

Answer 8

secondary cartilaginous
slightly mobile

when we get older decrease mobility

Question 9

1st sternocostal joint

Answer 9

between sternum and costal cart of ribs

primary cartilaginous- syndchondorsis
immoveable
don’t want to damage vessels that go through here

Question 10

2nd-7th sternocostal joint

Answer 10

between sternum and costal cart of ribs

synovial plane multiaxial

gliding movements in breathing

Question 11

costocondral joints

Answer 11

between ribs and cartilage

primary cartilaginous syndchondrosis

Question 12

intercondral joints

Answer 12

6-10
6-7, 7-8, 8-9- synovial multiaxial plane
9-10- fibrous

Question 13

costovertebral joints

Answer 13

synovial multiaxial plane

heads of ribs with boadies of the thoracic vert
1,10,11,12- articulate with single
rest articulate with superior and inferior vert

Question 14

costotransverse joints

Answer 14

synovial multiaxial plane

articular tubercle of ribs with transverse process
small gliding movements

ribs 11/12- dont have tubercles so no articulation

Question 15

radiate ligament

Answer 15

head of ribs to 2 adjacent vertebral bodies/ IVD
reinforce joint capsule

Question 16

intra articular ligament

Answer 16

head of ribs// ivd between vert bodies
divides costal vert joints cavities into 2

Question 17

superior costotransverse ligament

Answer 17

neck of ribs to transverse process of vert above

Question 18

lateral costotransverse ligament

Answer 18

tubercle of rubs to tip of transverse process of verterbrae at he level

Question 19

costotransverse ligament

Answer 19

back of neck to front of transverse process of corresponding vert

Question 20

inspiration pump handle

Answer 20

moves upper 2-5 ribs
increases the anterioposterior axis
movement axis along the neck of the ribs

Question 21

inspiration bucket handle

Answer 21

moves ribs 8-10
increase the lateral diameter
movement axis through costovertberal and sternocostal joints
