Cervical region Flashcards
What nerve indents the articular pillar of typical cervical vertebrae
the medial branch of the dorsal ramus of a cervical spinal nerve
What is the classic angulation of typical cervical articular facets
40-45 degrees from the coronal plane
Recent work suggests what angulation for typical cervical articular facets
55-60 degrees
What is the orientation of the typical cervical inferior articular facet
Forward, lateral, downward (FoLD)
What is the orientation of the typical superior articular facet
Backward, Upward, medial (BUM)
What muscles will attach to typical cervical articular processes
The longissimus capitis, longissimus cervicis, semispinalis capitis, semispinals cervicis, multifidis and rotators
What muscles blend with the capsular ligament of cervical zygapophysis
The semispinalis capitis, multifidis and rotator longus
What is the joint classification for the typical cervical zygapophysis
Synovial plane ( diarthrosis arthrodia) joint
What will influence spinal kinematics
Geometry of articular facets, mechanical properties of connective tissue, mechanical properties of muscle
The greatest range of flexion - extension among the typical cervical vertebrae occurs at which vertebral couple
Typically C5/C6
What motions are coupled in the cervical spine
Lateral Bending and axial rotation
Ranges of coupled motion among the typical cervical vertebrae will begin to decrease at what cervical vertebral couple?
C5/C6 Vertebral couple
What is the usual condition for the caucasian typical cervical spinous process
The are Bifid
What is the usual condition of the African-American typical cervical spinous process
they are non-bifid
What muscles may attach to the typical cervical spinous process
The spinalis cervicis, semispinalis cervicis, semispinalis thoracis, multifidis, rotators and interspinalis
