alignment of the body parts whether upright, sitting, or recumbent | POSTURE | |
How many vertebrae does the spinal column have? | 33 | (7 cervical, 12 thoracic, 5 lumbar, 5 fused sacral, and 3 or 4 coccygeal) |
this is a functional component of the spine that is madeup of vertebral bodies and intervertebral discs, and is the hydraulic, weightbearing, shock-absorbing portion of the spinal column | ANTERIOR PILLAR | |
this is the functional component of the spine that is made up of articular processes and facet joints, which provide the gliding mechanism for movt | POSTERIOR PILLAR/VERTEBRAL ARCH | |
these are the bony levers of the spine which is part of the posterior unit | 2 transverse processes spinous processes | (1) 2 transverse processes (2) spinous processes (to w/c the mm are attached to) |
the functional unit of the spine is composed of ____________ and ___________ | 2 vertebrae joints in between | 2 vertebrae joints in between (2 zygopophyseal facet joints and 1 IV disc) |
Where is the axis of motion in each unit of the spine? | NUCLEUS PULPOSUS | NUCLEUS PULPOSUS of the IV disc |
with flexion of the spine, the ant portion of the bodies (approximate, separate) and the spinous processes (approximate, separate) | approximate, separate | |
with extension of the spine, the ant portion of the bodies (approximate, separate) and the spinous processes (approximate, separate) | separate, approximate | |
with side bending, the lateral edges of the vertebral bodies (approximate, separate) on the side towards which the side of the spine is bending and (approximate, separate)on the opposite side | approximate, separate | |
rotation to the right results in relative movt of the body of the superior vertebrae to the (left, right) and its spinous process to the (left, right) | right, left | |
the superior facets of the lumbar spine are (flat, convex, concave) | concave | |
the inferior facets of the lumbar spine are (flat, convex, concave) | convex | |
it is the consistent association of one motion about an axis with another motion around a different axis | COUPLED MOTION | |
what are the components of the suboccipital region of the cervial spine? | occiput, atlas, and superior facets of the axis | |
it is a ball and sockt joint | OCCIPITAL-ATLANTAL JOINT | occiput-convex >> atlas-concave primary motions- fwd and bwd bending |
primary movt of the atlantoaxial jt | rotation | rotation is coupled with fwd and bwd movt of the articulating surfaces (side bending) -rot to the R >> fwd movt of the L arti surfaces and bwd movt of R arti surf of C1 on C2 - rot to the R, side bend to the R (v.v) |
angle of facet jts in a tyical cervical spine | 45 deg | typical cervical region-inf facets of the axis and the rest of th cervical spine;rot and side bending |
these are boney projections of the cervical spine that provide lateral stability to the spine and reinforcce vertebral discs posterolaterally | JOINTS OF LUSCHKA | |
coupling of rotation and side bending motions at the upper portion of the thoracic spine are in the (same, opposite) direction | same | |
coupling of rotation and side bending motions at the lower portion of the thoracic spine are in the (same, opposite) direction | opposite | |
coupling with lat flexion at the lumbar spine, rotation occurs to the (same, opposite) direction | same | |
coupling with rotation at the lumbar spine, lat flexion occurs to the (same, opposite) direction | opposite | |
what are the components of the intervertebral discs? | ANNULUS FIBROSUS, NUCLEUS PULPOSUS | -annulus fibrosus provides tensile strength -nucleus pulposus distribute pressure evenly throughout the disc; imbides water when pressure is reduced and squeezes water out under compressive loads (maintains tiss health and transport of nutrients) |
the outer portion of the annulus fibrosus is made up of _______ and ________ | COLLAGEN FIBERS, FIBROCARTILAGE | |
what are the ligamentous support of the annulus fibrosus? | ANTERIOR LONGITUDINAL LIGAMENT POSTERIOR LONGITUDINAL LIGAMENT | |
the nucleus pulposus is generally located at the center except in (cervical, thoracic, lumbar, sacral, coccyx) spine | LUMBAR | it is situated closer to the posterior border of the annulus fibrosus |
which component of the nucleus pulposus has great affinity for water? | PROTEOGLYCANS | high concentrations of proteoglycans, healthier spine |
dunring fwd bending of a vertebral segment, the ant part of the disc is (compressed, distracted) | compressed | |
dunring fwd bending of a vertebral segment, the post part of the disc is (compressed, distracted) | distracted | |
this covers the nucleus pulposus suply and infly and lie b/n the nucleus pulposus and vertebral body, and is encircled by the apophyseal ring of the respoective vertebral body |
