Cervical Spine Flashcards
transmit vertebral arteries
C1-6
cervical spine
thick discs
horizontal facets
less body mass
great range of motion and variety of movement
atypical
C1
C2
C7 - semi-atypical
tympical
C3-6
atlas
C1 - widest
- no body
- no spinous process
- lateral masses - to occipital condyles
- wides cervical vertebra
axis
C2 - strongest
- odontoid - dens - pivot
- bifid spinous processes
typical vertebrae
C3-6
vetrebra mediocris
C3-6
typical
concave superior body
convex inferior body
large triangle transverse foramen
superior facets superoposterior at 45 degrees
bifid spinous processes
vetrebra prominens
C7
most prominent
spinous process not bifid
small transverse foramen - no artery
hyoid
C3
thyroid
C4/5
cricoid
C6
first spinous process
C2
OA joint
occiput on C1
AA joint
atlas on axis
C1 on C2
atypical joints
OA and AA
typical joints
C2 on C3
to
C7 on T1
motion at OA
flexion-extension - MAJOR
rotation- sidebending - MINOR
rotation and sidebending in OA
opposite**
bc of anterior convergence of condyles
motions where somatic dysfunction are found
occipital condyles
anterior and inferior convergence of occipital condyles
hand cups
motion at AA
C1 on C2
major - rotation
minor - flex, extend, sidebend
AA joint rotation
50% of all C-spine rotation
to get ride of rest of rotation
flex C-spine up to C1
-locks out uncinate proceses
joints of luschka
uncinate processes
-small lips on superior surfaces of vertebral bodies
typical C-spine joints
rotation and sidebending- SAME SIDE
somatic dysfunction- all three planes
open facet
irritate tissues and can produce speed bumps
inducing flexion
slightly superior
inducing extension
slightly inferior
suboccipital muscles
occiput to C1 and C2
trapezius
extension of OA joint
SCM
lateral flexion of OA joint
scalene muscles
attach C3-7 to ribs 1 and 2
paraspinal muscles
attach occiput and C-spine to thorax
levator scapulae
transverse processes C1-4
-insert superior angle of scapula
to protect neurovascular
stay posterior to SCM
