muscles/actions
This muscle allows you to rotate your head to the opposite side and flex your neck.
Sternocleidomastoid
This is the primary motion that occurs in the lumbar spine
flexion/extension
This condition is caused by the bulging or rupture of an intervertebral disc
herniated disc
what is one complete gait cycle?
One leg completing both swing and stances phases
this motion is the greatest in the thoracic spine
lateral flexion
This group of three muscles runs along the spine and helps you stand upright.
Erector Spinae
What is the arthrokinematic motion for lateral flexion in thoracic spine?
Lateral Flexion-Ipsilateral facet glides inferiorly, contralateral facet glides superiorly
This exaggerated thoracic curvature is often seen in elderly individuals
kyphosis
when in stance phase on the L, which muscle must fire to stabilize the R leg that is in swing phase?
L glute med
This portion of the TMJ is convex
condyle of mandible
These deep muscles flex the neck and stabilize the cervical spine.
longus colli and longus capiitis
During lumbar flexion, the facet joints glide in this direction
superior and anterior
This spinal condition involves a lateral curvature of the spine.
scoliosis
Name all phases of the gait cycle
IC, LR, MS, TStance, PS, IS,MS, TSwing
this ligament prevents posterior displacement of the dens
transverse ligament
This posterior neck muscle extends the head and helps with posture, and it attaches to the occipital bone.
splenius capitis
Cervical rotation to the right results in this motion of the right facet joint
posterior and inferior glide
This injury occurs when one vertebra slips forward over another.
spondylolisthesis
During the terminal swing phase of gait, which muscle group contracts eccentrically to decelerate the swinging leg and prepare for heel strike
The hamstrings contract eccentrically during terminal swing to slow down knee extension and prepare the limb for initial contact.
Compression of this artery in the neck can cause dizziness or fainting during extreme head rotation
vertebral artery
Which muscle is firing when bending over to the R to pick up something with L hand?
R internal oblique
This is the arthrokinematic motion at the atlanto-occipital joint during flexion.
anterior roll and posterior glide of the occipital condyles
This degenerative condition leads to narrowing of the spinal canal, compressing nerves
spinal stenosis
During the loading response phase of gait, which muscle group is primarily working eccentrically to control the forward motion of the tibia?
The quadriceps and anterior tibialis work eccentrically during the loading response to control knee flexion and foot slap as the foot contacts the ground.
During anterior pelvic tilt, the lumbar spine does this motion
lordosis/extension
