#4: Anatomy and #5: Cervical DZ

Question 1

Openings in the transverse processes that allow vertebral artery and vein to exit are called?

Answer 1

foramen transversarium

Question 2

runs the entire length of the column in front of the body

Answer 2

Anterior longitudinal ligament

Question 3

This ligament runs the entire length spinal column but inside the spinal canal on the posterior aspect of the body

Answer 3

Posterior longitudinal ligament

Question 4

Posterior longitudinal ligament fx:

Answer 4

Weak resister to flexion

–protects from posterior disk herniations

Question 5

Anterior longitudinal ligament fx:

Answer 5

only ligament to limit extension

Question 6

Synovial joint between superior articular facet of inferior vertebra and inferior articular facet of superior vertebra
–held tightly by ligaments

Answer 6

zygapophysial ligaments

Question 7

This ligament connects lamina of vertebral arches

- elastic tissue, it resists sudden flexion and actually helps straight column from flexed position to original position

Answer 7

Ligamenta flava (yellow ligament)

Question 8

This ligament connects spinous processes and resist sudden flexion

Answer 8

Interspinous ligaments

Question 9

This ligament connects transverse processes and resist sudden lateral flexion and rotation

Answer 9

Intertransverse ligaments

Question 10

Vasculature of cervical vertebrae:

Answer 10

branches from vertebral and ascending cervical arteries

Question 11

Vasculature of Thoracic vertebrae:

Answer 11

branches from Posterior Intercostal arteries

Question 12

Vasculature of Lumbar vertebrae:

Answer 12

branches from Subcostal and lumbar arteries

Question 13

Vasculature of Sacrum and Coccyx:

Answer 13

branches from iliolumbar and lateral/medial sacral arteries

Question 14

Nerve supply to rest of vertebral:

Answer 14

recurrent meningeal branch off spinal nerve for each level

Question 15

Nerve supply to facet joints:

Answer 15

articular branches off spinal nerve for each level (posterior rami)

Question 16

Nerve supply to Intrinsic muscles of the back:

Answer 16

posterior rami off spinal nerve for each level

Question 17

Spinal nerve roots exit each vertebral level via:

Answer 17

intervertebral foramen
