3 vertebrae regions & how many
|
cervical vertebrae 7 - thoracic vertebrae 12 - lumbar vertebrae 5
|
|
|
cervical body description
|
small width
|
|

|
short bifid, projects posteriorly
|
|
|
cervical vertebral foramen description
|
triangular
|
|
|
cervical transverse process description
|
has foramina
|
|
|
thoracic body description
|
large heart-shape with demifacets
|
|
|
thoracic spinous process description
|
long sharp, points inferiorly
|
|
|
thoracic vertebral foramen description
|
circular
|
|
|
thoracic transverse process description
|
facet for ribs
|
|
|
lumbar body description
|
massive kidney-shaped
|
|
|
lumbar spinous process description
|
short blunt, project posteriorly
|
|
|
lumbar vertebral foramen description
|
triangular
|
|
|
lumbar transverse process description
|
thin + tapered
|
|
|
what features make the cervical vertebrae unique
|
transverse foramina - small bifid spinous process
|
|
|
what blood vessel is closely associated with the cervical vertebrae, how
|
vertebral arteries pass through transverse foramina on both sides to service brain
|
|
|
what separates vertebral bodies from each other and what are they made of
|
intervertebral discs which are made of fibrocartilage
|
|
|
what nervous structures exit the intervertebral foramina
|
spinal nerves
|
|
|
how do the ribs articulate with the thoracic vertebrae
|
head of rib articulate to demifacet on thoracic body - tubercle of rib articulate to facet on thoracic transverse process
|
|
|
how many articulating surfaces does T8 have
|
12
|
|
|
what is the clinical significance of the xiphoid process and the body
|
used to locate region for compression during CPR
|
|
|
can you palpate the jugular notch
|
yes
|
|
|
how are the ribs attached to the sternum
|
by individual costal cartilages
|
|
|
can you distinguish between the sternal and vertebral ends of each rib - how
|
vertebral end comprises of a facet + demifacet
|
|
|
which rib stands out as having a unique shape
|
first pair is flattened and broad forming a horizontal plate
|
|
|
can you clearly describe how the ribs articulate with the thoracic vertebrae
|
head of rib articulate with bodies of thoracic vertebra by 2 facets: 1 articulates with the demifacet of the same # thoracic vertebra, the other articulates with demifacet of thoracic vertebra immediately superior - tubercle articulates with transverse process of the same # thoracic vertebra
|
|
|
what are the spaces between ribs called
|
intercostal space
|
|
|
what structures travel in the costal groove
|
intercostal nerves + blood vessels
|
|
|
as a group, what are the first seven pairs of ribs called - why
|
true (vertebrosternal) ribs - attach directly to sternum by individual costal cartilages
|
|
|
as a group, what are the lower 5 pairs of ribs called - why
|
false(vertebrochondral) ribs - rib pairs 8-10 attach to sternum indirectly - each joins the costal cartilage
|
|
|
what name is given to the last 2 pairs of ribs - why
|
floating (vertebral) ribs - have no anterior attachment
|
