11) alar ligament
12) apical ligament
13) anterior and posterior atlanto-occipital membranes
14) anterior and posterior atlanto-axial membranes
15) iliolumbar ligament
Which ligament covers and connects the anterolateral aspect of the vertebral bodies and IVDs?
ALL
Which ligament extends longitudinally from the pelvic surface of the sacrum to the anterior border of the foramen magnum?
ALL
Which ligament’s fibers blend with the anterior atlanto-axial and atlanto-occipital membranes?
ALL
What is the function of the ALL?
test q
prevent hyperextension of the vertebral column
What is the most common way to injury the ALL?
car accidents
Which ligament is the only one that limits extension below the atlas?
test q
ALL (note: all other ligaments limit flexion)
Most ligaments of the vertebral column limit….
flexion
The intertransverse ligament limits….
anterior and lateral flexion
Are the interspinous ligaments weak or strong?
weak
Is the supraspinous ligament weak or strong?
strong
Which ligament connect lamina?
ligamentum flava
Which ligament contains yellow elastin that may constrict and prevents buckling into the spinal canal during extension?
ligamentum flava
Which ligament assists with straightening of the column after flexing?
ligamentum flava
What is the strongest ligament of the vertebral column?
nuchal ligament
Which ligament is a superior continuation of the supraspinous ligament?
nuchal ligament
Which ligament runs from the SP of C7 to the EOP?
nuchal ligament
The nuchal ligament provides attachment for….
muscles
Which ligament covers the posterior aspect of the vertebral bodies and IVD (mainly to IVDs)?
PLL
Which ligament runs from the body of C2 to the posterior surface of sacrum?
PLL
Which ligament weakly resists hyperflexion?
PLL
Which ligament has abundant pain receptors and can send lots of pain signals?
test q
PLL
Which ligament is a superior continuation of the PLL?
tectorial membrane
Which ligament runs from the body of C2 through the foramen magnum?
tectorial membrane
Which ligament limits both flexion and extension of the atlanto-occipital joint?
tectorial membrane
Which ligament forms the medial atlanto-axial joint (the ONLY ligament to form a joint)?
test q
transverse ligament
Which ligament extends between the lateral masses of C1 and facilitates rotation?
test q
transverse ligament
Which ligament facilitates rotation, but prevents cord compression during flexion?
test q
transverse ligament
Which ligament resembles a cross?
cruciate ligament
Which ligament is formed by the transverse ligament of the atlas and the superior and inferior longitudinal bands (different from longitudinal ligaments)?
cruciate ligament
note: the longitudinal bands primarily function to hold the transverse ligament in place
Which ligament extends from the sides of the dens to the lateral margins of the foramen magnum?
alar ligament
The alar ligament prevents/resists….
excessive rotation
Which ligament attaches to the superior apex of the dens to the anterior aspect of the foramen magnum?
apical ligament
Which ligament is weak and could be a remnant from the notochord?
apical ligament
Which ligament extends from the anterior arch of C1 to the anterior margins of the foramen magnum?
anterior atlanto-occipital membrane
The ALL blends with…
the anterior AA and AO membranes
Which ligament extends from the posterior arch of C1 to the posterior margins of the foramen magnum?
posterior atlanto-occipital membrane
Which ligament extends from the body of C2 to the anterior arch of C1?
anterior atlanto-axial membrane
Which ligament extends from the vertebral arch of C2 to the posterior arch of C1?
posterior atlanto-axial membrane
What is ponticulus posticus?
test q
-calcification of the posterior AO membrane
-a bony prominence arises from the posterior arch and/or the superior articular process (lateral mass) of the atlas
-the calcification can be complete or partially encircle the vertebral artery and the dorsal rami of C1 spinal n.
The lumbosacral joint is stabilized by the same typical ligaments that stabilize all vertebral joints from C2-S1. It is further strengthened by the iliolumbar ligaments that run from the TPs of _____ to the _______
L5, ilia
