Scoliosis |
|
|
Primary Curves |
Thoracic and sacrococcygeal |
|
|
Secondary Curves |
Cervical and lumbar |
|
|
first cervical vertebra, no body, no spinous process, bifid spinous processes, odontoid process |
Atlas |
|
|
fibrocartilaginous disc found between bodies, compresses to absorb shock |
intervertebral discs |
|
|
a label line is on the articular surface for ilium |
Sacrum |
|
|
opening between vertebrae through which spinal nerves emerge |
Intervertebral foramen |
|
|
sharp, downward spinous process, articular facets for ribs |
Thoracic vertebra |
|
|
short, blunt spinous process, large body compared to vertebral foramen |
Lumbar vertebra |
|
|
facet for articulation with occipital condyle of the skull |
Superior articular process |
|
|
the atlas rotates around this process |
Odontoid process or dens of axis |
|
|
body of sternum, intercostal space, costal cartilage |
thorax |
|
|
jugular notch, clavicular notch, manubrium, sternal angle, body, xiphoid process |
sternum |
|
|
provides the only bony articulation between the axial skeleton and the upper extremity |
clavicular notch |
|
|
where the manubrium meets the body, the second rib articulates here |
sternum angle |
|
|
landmark for locating attachment of diaphragm, superior surface of the liver, and right margin of the heart |
xiphoid process |
|
|
head, tubercle, body, and costal groove |
ribs |
|
|
facets for articulation with vertebral bodies |
head |
|
|
facet for articulation with transverse process |
tubercle |
|
|
located on inferior surface of the ribs, the grooves are formed by the intercostal nerves, arteries, and veins |
Costal groove |
|
|
originated on the sacrum; spinous processes of lumbar vertebrae. Inserts on the thoracic and cervical vertebrae, ribs, and skull. Acts bilaterally, extends head and vertebral column. Acts unilaterally, lateral flexion of head and vertebral column. Innervation - dorsal rami of spinal nerves |
Deep muscles of the back - erector spinae muscles -(Iliocostalis- most lateral, Longissimus - in between, Spinalis - most medial, located in thoracic region) |
