vertrebral joints/ligaments

Question 1

anterior longitudinal ligament

Answer 1

unite vertebral bodies on ant side

-stronger than posterior

Question 2

posterior longitudinal ligament

Answer 2

inture vertebral bodies on post side

-resis flexion

Question 3

ligamentum flavum

Answer 3

unites lamina

Question 4

interspinous ligament

Answer 4

unite spinous processes

-absent or lacking in lumbar

Question 5

supraspinous ligament

Answer 5

unite tips of spinous process

-stability in cervical/lumbar regions

Question 6

ligamentum nuchae

Answer 6

only in cervical region

• both spinous and interspinous ligaments
• substitute for bone and muscle attachment

Question 7

tranverse ligaments of atlas

Answer 7

holds dens against arch of atlas

-stabilize during rotation

Question 8

alar ligament

Answer 8

tip of dens to occipital condyles

-“check” for flexion/rotation

Question 9

apical ligament

Answer 9

tip of dens to internal occipital bone

-deep to cruciform

Question 10

cruciform ligament

Answer 10

• cross shaped
• superior part blends w/ apical lig
• inferior attaches to bodyy
• blends w/ transverse lig

Question 11

anterior atlantooccipital membrane

Answer 11

• attach anterior arch of atlas to anterior mrgin of foramen magnum
• continuation of ant long lig

Question 12

posterior atlantooccipital membrane

Answer 12

• attach posterior arch of atlas to posterior margin of foramen magnum
• continuation of ligamentum flavum

Question 13

tectorial membrane

Answer 13

body of axis to internal surface of occiptial bone thru foramen magnum

• superficial to cruciate lig
• continuation of post long lig

Question 14

zygopophyseal joint

Answer 14

• synovial joint btwn sup/inf articular processes
• gliding joints
• articular process lined w/ hyaline surrounded by loose connective tissue capsule
• ligamentum flavum stabilizes

Question 15

intervertebral joints

Answer 15

btwn vertebral body and IVD

-supported by ant/post long lig

Question 16

von luschka joint

Answer 16

• cervical region only

- btwn inf uncinate process to superior vertebrae

Question 17

sarcoiliac joint

Answer 17

• main connection btwn vert column and lower body

- btwn alar of sacrum and auricular surface of ilia

Question 18

craniovertebral joint

Answer 18

btwn occipital and atlas/axis

Question 19

atlantooccipital joint

Answer 19

synovial/condylar joint

• btwn sup articular face of atals and occipital condyles of skull
• allow flex/ext

Question 20

atlantoaxial joint

Answer 20

synovial joints btwn atlas and axis

• right/left articular processes of axis and atlas (gliding)
• dens process and anterior atlas arch
