Articular Process Flashcards
What is the name of the surface feature observed between the ends of the articular pillar?
The groove/sulcus for the dorsal ramus of a cervical spinal nerve
What is the classic angulation of typical cervical articular facets?
40 to 45 degrees from the coronal plane
Recent work suggests what angulation for typical cervical articular facets?
55 to 60 degrees
What is the orientation of the typical cervical superior articular facets?
backward, upward, medial (BUM)
What is the orientation of the typical cervical inferior articular facets?`
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 zygapophyses?
synovial plane (diarthrosis arthrodia) joint
What modifications of the synovial joint are observed in the cervical spine?
meniscoidal folds
What function will meniscoidal folds provide in cervical zygapophyses?
They are assumed to distribute pressure across the joint surface.
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 be similar for what cervical vertebral couples?
the C2/C3, C3/C4, C4/C5 vertebral couples
Ranges of coupled motion among the typical cervical vertebrae will begin to decrease at what cervical vertebral couple?
the C5/C6 vertebral couple
