cervical spin Flashcards
what ligament provides stability to spine
ligamentum flavum
what two movements happen at the Atlanta-occipital (C0-C1)
flexion and extension
what is an continuation of the posterior longitudinal ligament
tectorial membrane
what movements does the alar ligament limit
flexion and rotation
what joint of the spine is the most mobile articulation of the spine
Atlanta-axial joints(C1-C2)- flexion-extension, side flexion, rotation-primary Mvt of joint
what is the main supporting ligament at the atlanto-axial joint
transverse ligament
the superior facets of the cervical spine face
upward, posterior, and medially
the inferior facets of the cervical spine face
inferior, anterior, and laterally
the most flexion-extension of facet joints occurs where
C5-C6
close packed position of the cervical spin is
extension
