Question | Answer |
---|---|
ALL | ant. vert. bodies, Sacral promontory to C2 limits ext |
Ant. Atlanto Occipital lig | Atlas to occiput |
PLL | post. vert. bodies sacrum to C2 (ant portion of canal) wider in c-spine, thinner in t-spine, thinnest at L5 *thin and weak* prevent hyper flexion |
Tectorial membrane | PLL from C2 to occiput |
Ligamentum Flavum | "yellow ligament" lamina to lamina limits flexion and prevents buckling in extension |
Capsular ligament | articular process to articular process |
Inter transverse ligament | TVP to TVP limits lateral bending |
Interspinous ligament | between SP's prevents posterior translation and limits flexion |
Supraspinous ligament | SP's prevents hyperflexion |
Nuchal ligament | supraspinouse ligament C7-occiput |
transverse ligament | holds dens in fovea dentalis of atlas (indent on post. side of ant. tubercle |
cruciate ligament | C2-occiput, cross shaped, transverse ligament in horizontal portion |
alar ligament | 'check ligament' sides of dens to occipital condyles. limits rot of C2 |
apical ligament | apex of dens to ant aspect of foramen, limits flex and ext of C2 |
