1
Q

Anterior Longitudinal Ligament (ALL)

A
  • blends with anterior atlanto-occipital membrane

- runs down anterior aspect of vertebral bodies

2
Q

Posterior Longitudinal Ligaments (PLL)

A
  • Continous/becomes tectorial membrane

- runs within vertebral canal on posterior aspect of vertebral bodies

3
Q

Ligamentum flavum

A
  • yellowish color due to elasticity in it

- between adjacent lamina

4
Q

Tecorial Membrane attachements

A

-Attaches from posterior surface of axial body to anterior margin of foramen magnum

5
Q

Tectorial membrane function

A

supports atlanto-occipital & atalnto-axial joints

6
Q

Anterior atlanto-occipital membrane attachments

A

from anterior arch of atlas to adjacent occiptial bone

7
Q

Anterior atlanto-occipital membrane function

A

supports atlanto-occipital joints & helps to limit extension of the head

8
Q

Alar attachements

A

from dens to medial aspect of the occipital condyles

9
Q

Alar function

A

limits rotation of the median atlanto-axial joint

10
Q

Transverse (cruciate) of atlas attachments

A

from lateral mass to lateral mass of atlas

11
Q

Transverse (cruciate) of atlas function

A

maintains articulation between dens and anterior arch of the atlas

12
Q

Nuchal ligament attachments

A

from C7 spinous process to external occipital protuberance with slips to intervening spinous process
-becomes supraspinous ligament

13
Q

Nuchal ligament function

A

attachment for cervical muscles

15
Q

Ligaments of the spine

A
  1. ALL (anterior longitudinal ligament)
  2. PLL (posterior longitudinal ligament)
  3. Ligamentum flavum
16
Q

Lateral temporomandibular ligament attachments

A

from zygomatic process of temporal bone to mandibular neck

17
Q

Lateral temporomandibular lig function

A

supports joint capsule in maintaining articulation, & helps to limit depression & retraction

18
Q

Sphenomandibular attachements

A

from spine of sphenoid to lingula

19
Q

sphenomandibular function

A

a check ligament to prevent excessive depression

20
Q

Stylomandibular lig attachments

A

from styloid process to angle of the mandible

21
Q

stylomandibular lig function

A

taut during moderate opening

22

A

synovial: plane or gliding

27
Q

Lower compartment of temporomandibular joint

A

synovial: hinge or ginglymus

28
