Cards

Term
vertebral unit
Definition
two adjacent vertebrae, their joints, and the IV disc between them. given the name of the superior member of the unit.
Term
Spinal Unit
Definition
consists of two vertebrae and associated soft tissues
Term
capsular ligaments for facet articulations
Definition
contribute to stability and limitation of motion
Term
ligaments with high elastin content
Definition
can store kinetic energy that can be used to help restore segment to original position
Term
annulus fibrosis
Definition
fibrocartilage; bound with hyaline cartiliage above and below to each segment
Term
nucleus pulposus
Definition
gelatinous core of IV disc that acts to distribute and redirect stress and store energy
Term
Fryette Principle 1
Definition
when sidebending is attempted from neutral (anatomical) position, rotation of vertebral bodies follows to the opposite direction
Term
Fryette Principle 2
Definition
when sidebending is attempted from non-neutral position, rotation must precede sidebending to same side. motion occuring when the spine is in a position where facet structures determine the motion characteristics
Term
Fryette Principle 3
Definition
Motion introduced in one plane limits and modifies motion in the other planes
Term
sagittal plane
Definition
plane where flexion and extension occur about a transverse axis.
Term
neutral
Definition
point of balance of an articular surface from which all physioloic motions in that articulation take place. that range of forward bending (for T spine) or backward bending (for L spine) where the motion is not dependent upon the facets but on the body of the vertebrae
Term
neutral for T-spine
Definition
occurs with forward bending
Term
neutral for L-spine
Definition
occurs with backbending
Term
mechanincs of group curves
Definition
unilateral muscle contraction creates concavity (short-term, resolves with relaxation). Long-term anatomic adaptation associated with positional change (tissue change over time)
Term
group curves
Definition
spinal curve that involves several segments. compensatory changes often named according to this
Term
scoliosis
Definition
compensation in coronal plane. when the sacral base is unlevel, the body compensates to try to keep the eyes level. early in the process the thoracic and lumbar spine for a long C-shaped curve that is concave away from the short leg. with more time the compensatory mechanisms redistribute and an S-shaped curve forms with the lumbar concavity away from the short leg and the thoracic concavity towards the short leg
Term
Adams Test
Definition
patient bends forward at waist. monitor for symmetry of thoracic area, spinal line, and rib hump
Term
neutral mechanics
Definition
sidebending preceeds rotation
Term
Type I mechanincs
Definition
usually occur with groups of segments. greatest motion occurs towards the middle segments
Term
Non-neutral mechanics
Definition
rotation occurs first with sidebending following in the same direction. one segment usually close to the center of the group must rotate to the side you are trying to rotate to
Term
anatomic barrier
Definition
bony limit (ligamentous resistance increases as you approach this barrier)
Term
physiologic barrier
Definition
limit of active motion. soft tissue tension accumulation limits the active motion of an articulation. can be moved by doing warm-up exercises for the joint
Term
Flexion of Cervical Spine
Definition
50 degrees
Term
Extension of Cervical Spine
Definition
60 degrees
Term
Sidebending of cervical spine
Definition
45 degrees
Term
Rotation of Cervical Spine
Definition
80 degrees
Term
Flexion of Thoracic Spine
Definition
45 degrees
Term
Extension of thoracic spine
Definition
0 degrees
Term
Sidebending of Thoracic Spine
Definition
45 degrees
Term
Rotation of Thoracic spine
Definition
30 degrees
Term
Flexion of Lumbar Spine
Definition
60+ degrees
Term
Extension of Lumbar Spine
Definition
25 degrees
Term
Sidebending of Lumbar Spine
Definition
25 degrees
Term
Rotatio of Lumbar Spine
Definition
0 degrees
Term
left lateral recumbent
Definition
lay down on your left side
Term
transverse (horizontal) axis
Definition
sagittal plane rotates on this
Term
longitudinal (vertical) axis
Definition
transverse plane rotates on this
Term
anteroposterior axis
Definition
coronal plane rotates on this
Term
pivot joint (uniaxial)
Definition
a rounded process of bone fits into a bondy ligamentous socket, permitting rotation. Example: atlanto-axial joint
Term
plane joint
Definition
permit gliding or sliding movements. example: acromioclavicular joint
Term
hinge joint (uniaxial)
Definition
permit flexion and extension only. example: humero-ulnar joint
Term
ball and socket joint
Definition
multiaxial; a rounded head fits into a concavity, permiting movement on several axes. Example: pelvic-femoral joint
Term
saddle joint
Definition
biaxial; saddle shaped heads permit movement in two directions. Example: carpometacarpal joints
Term
condyloid joints
Definition
biaxial; permit flexion and extension, abduction and adduction, and circumduction. Example: metacarpophalangeal joint
Term
T2
Definition
level of suprasternal notch
Term
T4
Definition
angle of lewis aka sternal angle
Term
T9
Definition
level of xiphoid process
Term
L3-L4
Definition
level of umbilicus
Term
T3
Definition
level of spine of scapula
Term
spinous process of T7 and transverse process of T8
Definition
level of inferior angle of scapula
