Flashcards in Spinal Lecture 6 Deck (56)
What is the shape of the body of T4
The left sides of the upper 4-Tspine are flattened for ____
What is generally the stiffest segments of the spine?
Are pedicles in the L-Spine different then T-Spine?
The pedicles in the T-spine face more posterior
What is different about the lamina in the T-Spine vs. the L-Spine?
They are wider and overlap
What's the importance of the inferior and superior articulating process?
They determine movement based on the orientation of the facets
What is the orientation of the facets in the T-Spine?
Superior = posterior and lateral
Inferior = anterior and medial
What movement is facilitated or guided by the orientation of the facets in the T-spine?
Side bending and rotation
What restricts side bending and rotation at the T-Spine?
What is different about the SP's in the thoracic region?
Thinner – less muscle attachment and/or muscle aren't create as much force as in the lumbar spine
Pointing inferiorly – so much so in the lower portion that they begin to overlap
Why is the fact that the SP's in the t-spine overlap important for palpation purposes?
They will be found below the level of the vertebral body, so won't be placed where you think they are
Also the space between the SP's is extremely small
What is important about the tp's in the t-spine?
-still stout and thick because they articulate with the ribs
-ribs attach on the anterior aspect of the TP
How many regions is the t-spine broken into
what do the ribs articulate with in the t-spine
anterior aspect of TP's
If you have a vertebrae in disfunction what can this cause with regard to breathing?
a vertebrae in disfunction will ALWAYS cause a rib disfunction, which will negatively impact your breathing
if you have a rib injury what would you also what to treat
the thoracic vertebrae that the rib corresponds with
what happens to the vertebrae of the t-spine as you go lower down, specifically with regard to SP's
they are no longer overlapping and are a lot like the lumbar spine at this point
What is different between T1 and T2 with respect to the rib articulation?
The rib at that level articulates with one full rib and a bit of rib 2
Thoracic vertebrae of T1 is an ___ vertebrae
A typical vertebrae has articulation with part of _ ribs
Rib 1 articulates solely with ____
If the rib does not articulate with the TP, it is _____
What ribs in the t-spine have the most mobility
11-12 on everybody
Where do you get the most rotation in the T-spine and why?
-Lower t-spine due to the fact the ribs are not articulating with the TP's
-Ribs restrict side bending and rotation and because they do not attach in the lower t-spine you get more rotation through this area
What movement is restricted in the lumbar spine because of the orientation of the facets?
If you get a person to rotate where should you see most of the movement occurring?
If you have restriction through T9-T12 what could this cause?
If you don’t get rotation during normal walking then you are going to get more stress on the SI joint and hips. Therefore restriction at 9-12 can cause huge complications elsewhere
The head of the rib articulates with the.....
posterior aspect of the vertebral body, a larger facet on the superior aspect and a smaller facet on the inferior portion of the body along with the intervertebral disc
What is a consequence of the head of the rib articulating right into the vertebral disc in the t-spine?
Decrease mobility of the disc
