Anatomy

Question 1

ligaments flava

Answer 1

connects lamina of vertebral arches

AKA yellow ligament

Question 2

processes of vertebrae

Answer 2

Spinous
2 transverse

function in. muscle attachment and movement

Question 3

C2

Answer 3

Axis

head rotates on this

dens or odontoid processes

Question 4

annulus fibrosis

Answer 4

fibrous ring

outer layer of IV disk

Question 5

spinal cord runs

Answer 5

foramen magnum to L1 or L2

continues to spinal nerves (cauda equina)

Question 6

Atlanto-occipital joint location

Answer 6

between C1 & occiput of skill

Question 7

characteristics of thoracic vertebrae

Answer 7

articular faces are vertical = prevents flexion and extension (but can do rotation and lateral flexion)

long spinous processes

Question 8

Atlanto-axial joint location

Answer 8

between C 1 and C2

Question 9

sacral foramen

Answer 9

exits for sacral spinal nerves

anterior are larger than posterior foramen

Question 10

C1

Answer 10

Atlas

allows for lesion and extension

lateral masses support the head

Question 11

superficial intrinsic muscles

Answer 11

splenius

capitis, cervicis

Question 12

normal spine vertebrae break down

Answer 12

Cervical = 7
Thoracic = 12
Lumbar = 5
Sacrum = 5
Coccyx = 4

Question 13

IV disk is composed of

Answer 13

annulus fibrosus an nucleus pulposus

Question 14

anterior longitudinal ligament

Answer 14

runts entire length of vertebral column in front of the body

only ligament to limit extension

Question 16

foramen transversarium

Answer 16

fond in cervical transverse processes

site of passage for vertebral artery and vein

Question 17

deep intrinsic muscles

Answer 17

transversospinalis

semispinalis, multifdus, rotatores

Question 18

nucleus pulposus

Answer 18

central cell like fluid of IV disk

Question 19

Bodies of vertebrae separated by

Answer 19

intervertebral disk

Question 20

intermediate intrinsic muscles

Answer 20

erector spinae

iliocostalis, longissimus, spinalis

Question 21

curves of thoracic and sacral regions

Answer 21

kyphotic curves

Question 22

components of vertebrae

Answer 22

body
arch
articular facets
processess

Question 23

extrinsic muscles of back

Answer 23

superficial and deep

control limb and respiratory movement

Question 25

intrinsic muscles of the back

Answer 25

act on vertebral column only

produce muscle movement and posture

Question 27

characteristics of lumbar vertebrae (movement allowed(

Answer 27

flexion/extension/lateral flexion OK but no rotation

spinous processes are shorter and more squared off

Question 27

joint with minimal motion

Answer 27

sacroiliac

Question 28

posterior longitudinal ligament

Answer 28

protects form posterior disk herniation

Question 29

spinous processes by race/gender

Answer 29

bifid in males but not in females/African descent

Question 29

curves of cervical and lumbar regions

Answer 29

lordotic curves

Question 29

groups of intrinsic muscles

Answer 29

superficial intermediate deep layers

Question 30

dens location and ligament

Answer 30

anterior to SC and held by transverse ligament of Axis
