|
|
|
True or False: thoracic vertebrae have facet joints that are aligned vertically.
|
TRUE
|
|
|
|
True or False: when performing a sit-up with rotation to the right, the person is using his right internal and left external oblique muscles.
|
TRUE
|
|
|
|
True or False: The multifidi and rotators are extenders of the spine (bilateral) as well as rotators to the contralateral direction (unilateral).
|
TRUE
|
|
|

|
|
|
True or False: During the middle phase of trunk extension, the majority of motion occurs at the hip joints.
|
FALSE, lumbar spine
|

|
|
|
True or False: In the intracervical region: flexion motion is greater than axial rotation and axial rotation is less than lateral flexion ROM.
|
False: Rotation>flexion=lateral flexion
|
|
|
|
True or False: In the thoracic spine: extension motion is greater than axial rotation and axial rotation is less than lateral flexion ROM.
|
False: Rotation>lateral flexion=extension
|
|
|
|
True or False: In the lumbar spine: flexion motion is greater than axial rotation and axial rotation is less than lateral flexion ROM.
|
True
|
|
|
|
True or False: at the atlanto-occipital joint, extension is greater than lateral flexion which is greater than rotation.
|
True
|
|
|
|
True or False: Across the craniocervical region rotation has greater motion then extension which has greater motion than lateral flexion.
|
True
|
|
|
|
Define the term tight weakness.
|
Muscles kept in a habitually shortened position tend to lose their elasticity. They test strong only in the shortened positions but are weak as they are lengthened.
|
|
|
|
True or False: Protraction of the head is the result of flexion the lower cervical vertebrae and extension of the upper craniocervical region.
|
True
