Flashcards in Ligaments of vertebral column Deck (21):
1

Location of anterior longitudinal ligament

Runs from anterior tubercle of atlas to sacrum

2

What is the anterior longitudinal ligament united with

Periosteum of vertebral bodies

3

What does the anterior longitudinal ligament prevent

Hyperextension

4

Is the anterior or posterior longitudinal ligament stronger

Anterior

5

Location of the posterior longitudinal ligament

Runs from body of axis to sacral canal

6

What does the posterior longitudinal ligament prevent

Hyper flexion

7

What is the tectorial membrane

Thinner continuation of posterior longitudinal ligament, superior to axis

8

How are the anterior and posterior longitudinal ligaments named

Position relative to vertebral bodies

9

What colour is the ligamentum flavum
Why

Yellow
High elastic fibre content

10

Location of ligamentum flavum

Between laminae of adjacent vertebrae

11

When is the ligamentum flavum stretched

During flexion

12

Where is the interspinous ligament well developed
How does this aid it's function

Lumbar region
Gives stability during Flexion

13

Structure of Interspinous ligament

Weak sheets of fibrous tissue

14

What does the interspinous ligament fuse with

Supraspinous ligament

15

Location of interspinous ligament

Unite adjacent spinous processes

16

Location of supraspinous ligament

Unite adjacent spinous processes

17

Structure of supraspinous ligament

Strong bands of white fibrous tissue

18

When are supraspinous ligaments lax and tight
How does this aid function

Lax in extension and tight in flexion
Provides mechanical support of VC

19

Location of ligamentum nuchae

Runs between:
external occipital protruberance
Spinous processes of all cervical vertebrae

20

Functions of ligamentum nuchae

Maintains secondary curvature of cervical spine
Aids cervical spine in supporting the head
Major site of attachment of neck/trunk muscles

21

What are the ligaments of the VC

Anterior longitudinal ligament
Posterior longitudinal ligament
Ligamentum flavum
Interspinous ligament
Supraspinous ligament
Ligamentum nuchae
