Thoracic and Lumbar Spinal Mechanics

Question 1

cervical superior facet orientation

Answer 1

BUM

backwards, upward, medial

Question 2

thoracic superior facet orientation

Answer 2

BUL

backwards, upward, lateral

Question 3

Lumbar superior facet orientation

Answer 3

Backward, medial

Question 4

coupled motion - consistent association of a motion along/about one axis with another motion about/along another axis has what implications for the principal motion

Answer 4

principal motion cannot be produced without the associated motion occurring as well

Question 5

linkage is the

Answer 5

relationship of joint mechanics with surrounding structures

Specific joint assessment requires joint isolation

Question 6

because of linkage, in order to assess a joint where linkage occurs, one must

Answer 6

isolate the joint in question for accurate measurement and evaluation

Question 7

limit of active motion

Answer 7

physiological barrier

Question 8

limit of motion imposed by anatomic structure - limit of passive motion

Answer 8

anatomic barrier

Question 9

range between the physiolgoical barrer and anatomic barrier of motion in which passive ligamentous stretching occurs before tissue disruption

Answer 9

elastic barrier

Question 10

functional limit within the anatomic range of motion, abnormally diminishes the normal physiolgic barrier

Answer 10

restrictive barrier

Question 11

implications of spinal somatic dsyfunction

Answer 11

restrictions in motion of spine may reduce efficiency, impair flow of fluids, alter nerve function, and create structural imbalance

Question 12

when referring to vertebral motion, you are always referencing the _____ surface of the vertebra

Answer 12

superior/anterior surface

Question 13

when referring to vertebral motion, excessive or restrictive motion always refers to which vertebra

Answer 13

the vertebra above in the functional vertebral unit

Question 14

type one fryette mechanics

Answer 14

neutral
opposite direction for sidebending/rotation
tend to be groups

Question 15

type two fryette mechanics

Answer 15

in sufficient flexion/extension, sidebending and rotation occur in the same direction
tends to be a single vertebra

Question 16

name somatic dysfunction for

Answer 16

ease of motion

where it likes to be

Question 17

fryette’s third principle states

Answer 17

initiating movement of any vertebral segment in any place of motion will modify the movement of that segment in other planes of motion

Question 18

T1-3 spinous process vs transverse process

Answer 18

spinous process and transverse process are at the same level

Question 19

T4-T6 spinous process vs transverse process

Answer 19

Spinous process are 1/2 a segment below the corresponding transverse process

Question 20

T7-T9 spinous process vs transverse process

Answer 20

spinous process are at the level of the transverse process of the vertebra one below

Question 21

T10 spinous process vs transverse process

Answer 21

follow rules of T7-T9

spinous process are at the level of the transverse process of the vertebra one below

Question 22

T11 spinous process vs transverse process

Answer 22

follows T4-T6

spinous process 1/2 level below corresponding transverse process

Question 23

T12 spinous process vs transverse process

Answer 23

follows T1-T3

spinous process corresponds to transverse process
