|
longest region of the spine
|
thoracics
|
|
thoracics form what kind of curve
|
kyphotic
|
|
typical thoracics are
|
T1-T8
|
|
thoracic body is what shape
|
heart
|
|
spinous process of thoracic are
|
long and slop posteroinferiorly
|
|
T1 is atypical because
|
it is prominent, long, and has a horizontal spinous process
|
|
most common fractured vertbrae
|
T12
|
|
T12 is commonly fractured because
|
its superior half is thoracic like and allows for rotary movement. its inferior half is lumbar like and allows for extension and flexion
|
|
what kind of stress does T12 experience
|
transitional stress
|
|
thoracics have how many articular surfaces and what are they
|
4 articular surfaces
2 superior costal demifacets 2 inferior costal demifacets |
|
the head of the 6th rib articulates with
|
the superior demifacet of T6 and inferior demifacet of T5
|
|
smallest vertebral body of Ts
|
T3
|
|
transverse processes of thoraces project
|
posterolaterally
|
|
which thoracic has the greatest distance between the tips of the traverse processes?
|
T1
|
|
articular processes of the thoraces vertebrae are
|
small superior projections that are more vertical than cervical APs
|
|
superior articular processes of thoracics face
|
posterior, slightly superior, and lateral
|
|
the inferior articular processes of thoracics face
|
anterior, slightly inferior, and medial
|
|
the upper 4 spinous processes of thoracics project
|
posterior
|
|
the spinous of T5-T8 project
|
inferior
|
|
which SP is longest of T5 - T8
|
T8
|
|
thoracic vertebrae have a very prominent
|
inferior vertebral notch
|
|
smallest vertebral formane in spine
|
thoracic
|
|
T1:
|
transitional vertebrae
has a uncinate process body is more rectangular has 2 superior full facets that articulate with 1st rib |
|
T10
|
has 2 superior full facets
NO inferior demifacets |
|
has 2 superior full facets to articulate with the head of rib 11
|
t11
|
|
T11 has NO
|
transverse costal facets on the traverse processes
|
|
massive vertebral body of L1-L4 are what shape
|
kidney
|
|
function of lumbars
|
weight bearing
|
|
largest of all moveable vertebrae
|
L5
|
|
vertebral foramen of lumbar is
|
triangular
|
|
transverse processes of lumbars are
|
long and slender
|
|
the transverse process of lumbars have a
|
accessory process on posterior surface of inferior of each process
|
|
the superior articular processes of lumbars
|
- concave facets furfaces directed postromedially
- the facet is the vertical plane - the mammillary processes are on the posterior aspect of the superior articular process |
|
the inferior articular processes of lumbers are
|
- convex and anterolateral
- the facets surfaces are in the vertical plane - allow for flexion and extension motion |
|
the region of the lumbar lamina located between the superior and inferior articular processes is known as the
|
Pars Interarticularis
|
|
the spinous of lumbars are
|
short, sturdy, thick, broad, and hatch shaped
|
|
intervertebral foramen are located
|
from C2-sacrum
|
|
the first pair of IVF starts between
|
axis and C3
|
|
IVFs are smallest in
|
cervical
|
|
largest sized IVFs are used for
|
spinal flexion
|
|
smaller size IVFs are used for
|
spinal extension
