Thoracic Spine
The articulation between a rib tubercle and a vertebra
What is a costotransverse joint?
Shape of lumbar spinous processes compared to thoracic
What is shorter and thicker?
Close-packed position of the SI Joint
What is nutation?
The weakest area of the lumbar disk
What are the posterolateral corners of the annulus fibrosus?
Effect of a tight iliopsoas on the pelvis and lumbar spine
What is anterior tilt and increased lordosis?
The direction of vertebral rotation versus sidebending in thoracic scoliosis
What is contralateral?
The motion restricted by the ligamentum flavum
What is lumbar flexion?
The strongest ligament in the SI joint region
What is the interosseous ligament?
A strong sidebending force couple in the lumbar spine
What are the quadratus lumborum and contralateral gluteus medius?
Support for pelvic organs and urogential function
What are some functions of the pelvic floor muscles?
The direction of arthrokinematic rib tubercle motion during INHALATION
What is superior roll and and inferior glide?
The orientation of a typical lumbar superior articular facet
What is medial (and posterior)?
R PSIS high and R ASIS low compared to L
What is R anterior innominate rotation, OR what is L posterior innominate rotation?
A muscle that quickly atrophies in the presence of low back injury/pain
What is the multifidus?
Effect that half-kneeling on the L knee has on innominate positions
What is L innominate anterior rotation and R innominate posterior rotation?
The direction of the axis for "pump handle" rib motion.
What is medial/lateral?
The arthrokinematics of right lumbar rotation
What are left approximation and right gapping?
The correct description of R lateral pelvic tilt
What is when the R pelvis drops lower than the L side?
The abdominal muscle least able to produce trunk flexion torque
What is the transversus abdominis?
The position of the L ILA in a R on L sacral torsion
What is anterior?
Ventilatory action of the serratus posterior superior.
What is forced inspiration?
The predominant motion in the LAST 25% of trunk flexion
When the sacral apex moves posterior and superior
What is nutation?
The actions of the liopsoas on the lumbar spine, the trunk, and the lumbosacral junction
What are lumbar sidebending/extension, trunk flexion, and lumbosacral flexion?
The position of the L sacral base and R sacral ILA in a L on R sacral torsion
What is L sacral base posterior and R ILA anterior?
