Cervical Flashcards
Typical cervical vertebra body
- superior surface is concave w 2 unicate processes
- inferior surface is convex w 2 facets
- -> creats uncovertebral joints
typical cervical pedicles
- orientated pos. lat.
- spinal nerve passes just above the sup vertebral notch
typical cervial laminae
relatively narrow
typical cervical transverse processes
directed lat. and ant. and slightly inf.
the transverse foramen for vertebral artery and vein (C7 just accomidates vein)
typical cervical Superior articular process
has superior articular facet that is orientated superiorlu and post
typical cervical inferior articular process
- has a non articular part that serves for muscle attachments
- articular surface, that is orientated inf and ant.
Features of C1
-VB absent
Anterior arch- has facet for the dens
Posterior arch- has groove for the vertebral artery/vein
SA facet- kidney shaped, biconcave, orientated anterior medially
IA facet- round, orientated inf and med.
SP- absent, replaced by post. tubercle
VF- largest (rule of thirds- 1/3 dens, 1/3 spinal cord, 1/3 space)
features of axis
VB- location of the dens, ant surface of dens has ant articular facet for atlas SP- bifid TP- orientated lat + inf sup AP- round, orientated sup + lat inf AP- round/oval, orientated ant + inf
features of C7
Longest and most prominent SP
transverse foramina house vertebral veins only
features of c6
very large anterior tubercle of TP taht relates in space w common corotid
borders of intervetebral foramen
ant- uncovertebral
inf- superior vertebral notch
post- Z joint
sup- inf vertebral notch
biomechanics of the cervical spine (most rot, flex, exten)
-overall spine reg w the most rom
c1-c2: greatest deg of axial rot
C2-7: most flex, ex, fair lateral flex
Jefferson fracture
fall directly on head
burst fracture of c1
hangmans fracture
traumatic spondylosis of C2
