A

intervertebral disc

17
Q

What does intervertebral disc consist of?

A

a softer central nucleus pulposus and a thicker annulus fibrosis (fibrocartilage).

18
Q
A
  1. Lumbosacral articular surface
  2. Sacral promontory
  3. Linea terminalis
  4. Sacral foramina
  5. Transverse process of the coccyx
  6. Coccyx

  3. Median sacral crest
  4. Intermediate sacral crest
20
Q

How many vertebrae does the sacrum consist of?

A

5 fused sacral vertebrae

21
Q

How many vertebrae does the coccyx consist of?

A

4 fused coccygeal vertebrae

22
Q
A
  1. Anterior atlantooccipital membrane
  2. Atlantooccipital joint capsule
  3. Lateral atlantoaxial joint (capsule removed)
  4. Anterior longitudinal ligament
  5. Lateral atlantoaxial joint capsule
23
Q
A
  1. Posterior atlantooccipital membrane
  2. Ligamenta flava
  3. Ligamentum nuchae
  4. Zygapophyseal joints
24
Q

What are the 4 joints of cervical spine?

A
  1. the atlantooccipital joint (C1 and occipital bone)
  2. the atlantoaxial joint (C1 and C2)
  3. the zygapophyseal joints (facet joints)
  4. the intervertebral joints.
25
Q

Describe the atlantooccipital joint

A
  • C1 and occipital bone

- an ellipsoid joint;

26
Q

Describe the atlantoaxial joint

A
  • C1 and C2

- a plane and pivot joint

27
Q
A
  1. Posterior longitudinal ligament
  2. Tectorial membrane
  3. Atlantooccipital joint capsule
  4. Lateral atlantoaxial joint capsule
  5. Zygapophyseal joint capsule (C2-3)
28
Q
A
  1. Alar ligaments
  2. Superior longitudinal band
  3. Transverse ligament of the atlas
  4. Inferior longitudinal band
  5. Cruciate ligament

( The atlantoaxial joint (C1-2) is primarily a joint of rotation. The apical, alar, and cruciate ligaments provide stability to the joint. Of these, the transverse ligament of the atlas is biomechanically the strongest.)

29
Q
A
  1. Anterior longitudinal ligament
  2. Intervertebral discs
  3. Supraspinous ligament
  4. Interspinous ligament
30
Q
A
  1. Posterior longitudinal ligament
  2. Ligamentum flavum
  3. Iliolumbar ligament
  4. Dorsal sacroiliac ligament
  5. Sacrospinous ligament
  6. Sacrotuberous ligament
31
Q

Course of the anterior (1) and posterior (5) longitudinal ligaments

A

They run along the anterior and posterior vertebral bodies the entire length of the spinal column and prevent excessive extension (anterior) and flexion (posterior) of the spine.

32
Q

Course of the supraspinous (3) and interspinous (4) ligaments

A

The supraspinous and interspinous ligaments run between each pair of spinous processes

33
Q

Course of the ligamentum flavum

A

It runs between the laminae.
