quiz #8 - spine Flashcards
cervical spine
facet joints
intervertebral joints
thoracic spine
facet joints
intervertebral joints
ribs
lumbar spine
facet joints - L5, S1 facet joints
intervertebral joints - L5, S1 intervertebral
facet joints
inferior facets of vertebra above articulate with superior facets of vertebra below
intervertebral joints
consist of intervertebral disc lying in between two adjacent vertebra
all three form a fibrocartilaginous joint that allows slight movement
facet/ zygopophyseal joint - type & movements
synovial, plane, diarthrosis, uniaxial
gliding, flexion, extension, some lateral flexion with rotation
facet/ zygopophyseal joint - articular surfaces
inferior condylar facet of superior vertebra, superior condylar facet of inferior vertebra
facet/ zygopophyseal joint - accessory ligaments
-articular capsule
-supraspinous
-interspinous
-ligamentum flavum
-intertransverse
cervical spine - coupled motions
motions that always occur together
-in entire spine, rotation & lateral flexion always occurring together except at C1/C2:
due to shape & orientation of bones & joints
C2-T5 - coupled motions
lateral flexion & rotation on ipsilateral side (same)
T6-L5 - coupled motions
lateral flexion & rotation on contralateral side (opposite)
spine - loose packed position
midway between flexion & extension
spine - close packed position
full extension
capsular pattern of restriction
side flexion & rotation equally limited, then extension
intervertebral joints - type & movements
cartilaginous, symphysis, amphiarthrosis, triaxial
flexion, extension, lateral flexion & some rotation
