Thorasic

Question 1

what do the thorasic transvesrs processes look like?

Answer 1

thick, strong and long

Question 2

what do the spinous processes look like?

Answer 2

long and slender

Question 3

what do the costovertebral joints articulate with?

Answer 3

rib heads

Question 4

what do the costotransvers joints articulat with?

Answer 4

tubercles of ribs.

Question 5

what angle are the articular fascets of the throasics a from transverse to coronal plane?

Answer 5

Thorasic articular fascets form a 60 degree angle up to head

Question 6

what is the angle of the fascets from the coronal to the saggital plane?

Answer 6

20 degrees from cornonal to saggital plane

so, the inferior facets face down, medially and forward while the superior facets face opposite.

Question 7

So the direction of the inferior fascets are?

Answer 7

face down, middle and the front

Question 8

what direction of the superior fascets?

Answer 8

face up, back and out

Question 9

what is signifigant about the first and last throasic vertebrae?

Answer 9

they are a combination of the cervicals or thorasics they look different

Question 10

what the the throasic curve

Answer 10

Kyphotic curve with and average of 45 degree, this is a primary curve, you are born with it.

Question 11

where is the apex of the thorasic curve?

Answer 11

at T6-T7 disk space.

Question 12

what will flattening the thorasice curve do to the cervical and lumbar curves?

Answer 12

it will shift the cervical curve forward while decreaseing the curve, it will increase the lumbar curve.

Question 13

what is the thoracic disk height to body height ratio?

Answer 13

Disc to body ratio is 1:5,this is the smallest ratio of spine. remember that cervical was 2:5

Question 14

what is the difference between the cervical and thoracic nucleus pulposus location?

Answer 14

Cervical is slightly posterior while thorasic is centered.

Question 15

what is one reason the throasic spine is less flexable?

Answer 15

it has a small disk to body height ratio of 1:5

Question 16

what is the combined flexion range of a throasic spinal segments?

Answer 16

6 degrees average, but its about 4 degress at the top and 12 degrees at the bottom

Question 17

what are the movements of throasic flex/extend?

Answer 17

saggital rotation with slight saggital plane translation.

Question 18

what happens to fascets during throasic flexion?

Answer 18

fascets glide apart and disk opens in back.

Question 19

what happens to fascets during throasic extension?

Answer 19

fascets joints and posterior disk approximate.

Question 20

average lateral flexion of thrasic?

Answer 20

average is 6 degrees on each side.

Question 21

what movements are coupled for upper thoracic rotation?

Answer 21

Upper thrasic lat flexion and rotation will occur to the same side, like airplane

Question 22

What are the coupled movements for middle and lower thorasic later flexion

Answer 22

the middle lat flexion can cause the rotation to occur in either direction.

Question 23

In general what happen to the disk and fascet joint of the throasic joints during lateral flexion?

Answer 23

They both approximate on side of flexion and separate on the opposite side

Question 24

Specifically for the upper thorasics, what ways does the fascet joints move during lat flexion?

Answer 24

Upper thoracic, the inferior fascets glide medially on side of flexion and laterally on opposite side of flesion, basically they tip toward the flesion.

Question 25

how far does upper thorasics rotate?

Answer 25

8-9 degrees on each side, it decreases as you go down the thoracics.

Question 26

what movement us upper thorasic rotation coupled with?

Answer 26

Upper thorasic rotation is coupled with same side lateral flesion.

Question 27

how do inferior fascets of rotating thoracic move?

Answer 27

They glide down on side of rotation and glide up on side opposite. Think that they can just rotate, they have to get around the upper facets of the vertebrae below. The inside inferior facet dives down and the outside inferior facet jumps over. (sort of)

Question 28

what movements do thorasices do best and worst?

Answer 28

worst at lateral flesion, pretty good at flesxion and estension at bottom and good at rotation at top.

Question 29

what are the three rib motions?

Answer 29

Pump handle, bucket handle and caliper

Question 30

Where does rib pump handle action occur?

Answer 30

at T1-T6, it?s the movement of the ribs up and foreward while inhaling

Question 31

Where does rib bucket handle action occur?

Answer 31

at T7-T10, it?s the movement of rib elevating it out to side and depressin,

Question 32

What is the purpose of the T7-T10 bucket handle action?

Answer 32

to increase transverse diameter of ribcage

Question 33

what is the purpose to T1-T6 pump handle action?

Answer 33

to increases the A-P, front to back diameter of rib cage maybe

Question 34

Where does caliper rib action happen?

Answer 34

T-8 to T12, it overlaps a bit with bucket handle

Question 35

What is the caliper rib action?

Answer 35

ribs move laterally out with inhalation to increase the lateral diameter of rib cage.

Question 36

what are the movements of thorasic lateral flexion?

Answer 36

down on side of flex, up on side opposite of flex.
