Thoracic Spine Flashcards
how are the facet joints oriented.
20 degrees from the frontal plane
which two ligaments are larger in the T spine
ligamentum flavum
anterior longitudinal ligament
what happens to the rib distortion during left rotation?
same side: posterior convexity, anterior flattens
opp side: posterior flattens, anterior convexity
the line of gravity falls ____ promoting ____.
anterior, flexion
what two structures do the thoracolumbar fascia surround?
erector spinae and multifidus
what is the function of the thoracolumbar fascia?
compression/stability
actions (2) and role of deep erector spinae.
extension, ipsilateral flexion, causes posterior shear
what is the unstable position for the erector spinae muscle group.
full flexion
action of superficial erector spinae.
extension & lateral flexion
what is the flexion-relaxation phenomenom?
as you flex forward greater than 2/3 ROM, motion relies on passive structures such as ligaments
Someone with a left rib hump and right lateral flexion would have what type of scoliosis.
left scoliosis
what is the motion of T1-T6 costotransverse joint?
convex on concave, rotation
what is the motion of T7-T10 costotransverse joint?
flat, gliding
what is the motion of costovertebral joint?
rotation and gliding
we lose elasticity of ____ ____ as we get older and we cannot expand our lungs as wide.
costal cartilages
