25
Movement at ribs 1 - 6 of Costotransverse joints? And why does it happen?
- Slightly convex facets = slight rotation of rib = elevation/depression movements at sternal end - Pump-handle movement
26
Movement at ribs 7- 10 of Costotransverse joints? And why does it happen?
- Flatter facets = gliding movement = elevation/depression in lateral portions of ribs - Bucket-handle movement
27
Location of the Costochondral joints?
Anterior end of rip and costal cartilage (ribs 1-12)
28
Classification of the Costochondral joints?
Cartilaginous, synchondrosis, slightly movable
29
What are the Costochondral joints made of?
Made of hyaline cartilage
30
Location of the Sternocostal joints?
Between costal cartilage of rib and sternum
31
Classification of the 1st Sternocostal joint?

No
33
Classification of the 2nd - 7th Sternocostal joints?
Synovial, uniaxial, gliding
34
What makes the 2nd - 7th Sternocostal joints different to the 1st?

Cartilaginous, synchondrosis, slightly movable
43
What is the Xiphisternal joint made of?
Hyaline cartilage
44
Location of the Posterior longitudinal ligament?
- Runs inside the vertebral canal | - From the posterior part of the C2 to the sacral canal
45
Function of Posterior longitudinal ligament?
Helps prevent hyperflexion of V.C.
46
Location of the Interlaminal ligament/Ligamentum flavum?
Between the C2 and C3 to the sacrum
47
Function of the Interlaminal ligament/Ligamentum flavum?
Helps preserve normal curvature and straightens vertebral column after flexion
48
Location of the Interspinous ligament?
Between the adjacent spinous process
49
Location of the Supraspinous ligament?
- Between the tips of the spinous processes | - From C7 to the sacrum
50

51
Location of the Nuchal ligament?
From C7 to the external occipital protuberance
52
Function of the Nuchal ligament?
Maintains cervical curvature and keeps head upright on C1
53
Location of the Intertransverse ligament?
Between transverse processes
54
Function of the Intertransverse ligament?
Limits lateral flexion of the spine
55
