Anterior LongitudinalLigament Extends :
from occipital bone to sacrum : Stabilizes helps prevent
hyperextension of back
Posterior Longitudinal Ligament :
Extends from C2 to sacrum :
helps limit hyperflexions reinforces discs : narrowers weaker than Anterior Longitudinal
Ligamentum Flavum :
snock absorber allows for movement allows for rotation of vertebral column
, ,
Intervertebral Disos :
Anhulus Fibrosis Outer
:
fibrocartilage that creates
strong bond between vertebrae'
allows for movement
Nucleus Pulposus shock :
absorber
,
allows for movement , allows for rotation of
vertebral column
Appendicular Muscles: Muscles that more the upper Blower limbs as well move/stabilize the pectoral 3 pelvic girdles
