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