Week 3 Flashcards
Thoracic and Vertebral joints and ligaments
1
Apical ligament
Name and classify the joint between the xiphoid process and the body of the sternum.
Name: Xiphisternal joint
Classification: Consists of hyaline cartilage making it a: Cartilagenous, Synchondrotic, Amphiarthrotic joint.
10
Vertebral Canal (or individually known as vertebral foramen)
What joint is the green arrow pointing to?
The intervertebral disc joint between L5 and the Sacrum (S1)
What is the supraspinous ligament a continuation of?
The Nuchal ligament
10
Left atlanto-occipital joint
1
Tectorial mebrane (cut)
For the Atlanto-Occipital joint:
- Name the bony features involved in the joint
- Classify it
- What movements are possible at this joint and what planes do they occur in?
- Name the 2 membranes connecting the skull to C1. What are thier roles?
- Superior articulating facets of C1 to the occipital condyles of the skull
- Synovial, Biaxial, Condyloid
- Sagital plane: Nodding (flexion/extension), Coronal Plane: Lateral Flexion
- Anterior and posterior Atlanto-Occipital membranes. both help to prevent excessive movement of the joint.

Anterior atlanto-axial membrane
4
Anterior atlanto-axial membrane
For the interchondral joints:
- How are these joints numbered? (give example)
- Which ribs are involved?
- what parts are involved in this joint?
- What is the classification of each?
- Name the ligaments that support the interchondral joints?
- By intercostal space (Below 5th rib is 5th intercostal space = 5th intercostal joint
- Between ribs 5-10
- Costal cartilages of the above and below rib
- 5th and 9th = Fibrous, syndesmostic, amphiarthrotic. 6th, 7th and 8th = Synovial, Uniaxial, gliding.
- The interchondral ligaments
5
Posterior longitudinal Ligament
State the bony attachements for the lateral costotransverse ligaments?
Tip of the transverse process to the rough non-articular part of the costal tubercle of the rib.
12
Interspinous ligament
1
Body of atlas
1
Joint capsule of atlanto-occipital joint
7
Interspinous ligaments
Name the two highlighted joints.
Green: Costotransverse
Pink: Costovertebral
8
Posterior atlanto-axial membrane
13
Costotransverse joint
The apical ligament is a remenant of what structure?
The Notochord
For the Anterior Longitudinal Ligament:
- On its decent what bony feature does this ligament attach to on C1?
- Where does this ligament ultimately end?
- What two structures of the vertebral column does it attach to on its way down?
- What is the specialised function of this ligament?
- What is the most superior attachment for this ligament?
- Anterior Tubercle of C1
- Pelvic surface of sacrum
- The anterior vertebral bodies and the annulus fibrosis of the I.V discs
- Prevents hyperextension of the vertebetral column
- Basilar part of occipital bone
