Typical Cervical Vertebrae C3-C6 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 degree
What is the orientation of the typical cervical superior articular facet?
Backward, upward, medial (BUM)
What is the orientation of the typical cervical inferior articular facet?
forward, lateral, downward (FoLD)
What muscles will attach to typical cervical articular processes?
The longissimus capitis, longissimus cervicis, semispinalis capitis, semispinalis cervicis, multifidis and rotators
What muscles blend with the capsular ligament of cervical zygapophyses?
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?
The C5/C6 vertebral couple
What is the usual condition for the Caucasian typical cervical spinous process?
They are bifid
What is the usual condition for the African-American typical cervical spinous process?
They are non-bifid
What muscles may attach to the typical cervical spinous process?
