105- Cervical And Thoracic Test Flashcards
Three joints of thoracic vertebrae
Costovertebral costotransverse zygapophyseal
Avulsion fracture does what
Ligament pulls a bony fragment away
Clay shovelers fracture is
An avulsion fx of a spinous process. Seen on swimmers view
Jefferson fracture is
Comminuted fx of the ring of C1
Hangman fracture
Fracture of anterior arch of C2 as a result of hyper extension
With reference to MSP, how do zygapophyseal joints of cervical vertebrae open
90 degrees anterior
With reference to msp, how do zygapophyseal joints of thoracic vertebrae open
70 degrees anterior
When cervical spine is in flexion, spinous processes are
Elevated
When cervical spine is in extension, spinous processes are
Depressed

Primary curves of spine
Thoracic and pelvic
Secondary curves of spine
Cervical and lumbar
Convex anteriorly
Cervical and lumbar
Concave anteriorly
Thoracic and pelvic
Articular processes form short thick columns of bone called
Articular pillars
Thoracic vertebrae have _____, that cervical and lumbar do not
Costal facets and demifacets
T2-8 contain demifacets where
Superiorly and inferiorly
T9 has demifacets where
Only superior
T10-12 have a ____ at the ____
Single whole facet; superior margin
T1 has a _____ at the _____ and a ____ at the_____
Whole costal facet; superior border; demifacet; inferior border
Intervertebral joints are what kind of joints with what kind of movement
Cartilaginous symphysis; slight movement
Zygapophyseal joints are what kind of joints with what kind of movement
Synovial gliding; freely movable
Atlantoocipital joint is the articulation between what
Atlas and occipital bone
The atlantoocipital articulation is what kind of joint with what kind of movement
Synovial ellipsoidal; freely movable
The anterior arch of the atlas and the deans of the axis forms the
Atlantoaxial joint
The atlantoaxial joint is what kind of joint with what kind of movement
Synovial gliding and pivot; freely movable
Costovertebral and costotransverse joints are what kind of joints with what kind of movement
Synovial gliding; freely movable
Fuchs view is used when
The upper half of the dens is not clearly shown with the open mouth position
With open mouth view, if incisors are projected over the dens, the neck is:
Flexed too much toward the chest
With open mouth view, if the base of the skull is projected over the dens, the neck is:
Extended too much
The ottonello method or “wagging” jaw is used to
Blur the mandible for the AP view of c spine
