Unit 3 Thorax

Question 1

Lumbocostal ligament

Answer 1

TVP of L1 to Rib 12.
Acts like iliolumbar ligament. Acts as anchor.

Question 2

Intertransverse ligament

Answer 2

Limits how much TVPS can move away from one another, limit flexion but also side bending.

Question 3

Lateral costotransverse ligament

Answer 3

TVP of vertebrae to rib of same number.

Question 4

Radiate ligament

Answer 4

Wrapping like circle around the rib head.
Maintains articular relationship of ribs 2-10 with intervertebral space.

Question 5

Ligamentum Flavum:

Answer 5

Connects adjacent vertebrae in the thoracic and lumbar regions, providing stability and resistance to flexion.

Question 6

Supraspinous Ligament

Answer 6

Connect spinous processes on superior aspect of SP’s, offering support and limiting excessive flexion.

Question 7

Interspinous ligament

Answer 7

Connects adjacent spinous processes, offering support and limiting excessive flexion.

Question 8

Orientation of Superior facets of throacic spine

Answer 8

BUL = Back, upwards slightly and lateral

Question 9

Orientation of Superior facets of lumbar spine

Answer 9

Back & Medial

Question 10

Prefered motion of Thoracic spine

Answer 10

Flexion/ extension then side bending
Secondary is rotation

Question 11

Only long bone of the body that is horizontal

Answer 11

Clavicle

Question 12

What is the bony articulation between the Upper limb and the trunk

Answer 12

Clavicle

Question 13

Global motion of the thorax

Answer 13

Increase AP diameter of thoracic cavity

Question 14

Breathing in motions of the thoracic cage

Answer 14

Angles of ribs descend
Lifts sternum up and out to increase anterior and posterior distance in thoracic cavity to allow us to breathe and lungs expand.

Question 15

Breathing out motions of the thoracic cage

Answer 15

Angles of ribs ascend when exhaling.

True ribs

Question 19

Ribs 8-10

Answer 19

Articulate on costal cartilage of ribs 6 “hijack cartilage of rib 6”
False ribs

Question 20

TVP’s articulate with
Bodies of vertebrae articulate with

Answer 20

TVP : angle of rib
Body: head of rib

Question 21

Costal groove

Answer 21

Pathway for intercostal NVAL
Short, shallow depression found along body rib
Lateral to tubercle and travels along the internal surface of the body, adjacent to inferior border and gradually becomes indistinguishable as it travels to ant part of body
