VI. Regions of the Vertebral Column: Cervical Region: Typical Cervical Vertebrae C3-C6 Part 3 Flashcards
Recent work suggests what angulation for typical cervical articular facets?
55 to 60 degrees
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, multifidus and rotators
What muscles blend with the capsular ligament of cervical zygapophyses?
the semispinalis capitis, multifidus and rotator longus
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 couple motion along the typical cervical vertebrae will be similar for what cervical vertebral couples?
the C2/C3, C3/C4, C4/C5 vertebral couples
Ranges of couple motion along the typical cervical vertebrae will begin to decrease at what cervical vertebral couple?
the C5/C6 vertebral couple
What muscles may attach to the typical cervical spinous process?
the spinalis cervicis, semispinalis cervicis, semispinalis thoracis, multifidis, rotators and interspinalis
What will form the unique anterior boundary of a typical cervical intervertebral foramen?
the uncinate process of the segment below and lateral groove of the segment above forms the joint of Luschka
