Typical Cervical Vertebrae Flashcards
What muscles will attach to the anterior tubercle of a typical cervical vertebra?
Anterior scalene, longus capitis, longus colli, anterior intertransversarii
What muscles may attach to the posterior tubercle of a typical cervical vertebra?
Splenius cervicis, iliocostalis cervicis, longissimus cervicis, levator scapula, middle scalene, posterior scalene, rotators and posterior intertransversarii
What muscles will attach to the costotransverse bar?
Middle scalene and posterior intertransversarii
What is the name given to the superior margin of the costotransverse bar?
Sulcus for the ventral primary ramus of a cervical spinal nerve
What is the orientation and angulation of a typical cervical transverse process?
60 degrees anterolaterally (from midsaggital plane), 15 degrees inferiorly (from the horizontal plane)
What is the name given to the modification of the anterior tubercle of the C6 transverse process?
The carotid tubercle
What will cause remodeling of the anterior tubercle at C6?
The common carotid artery
What will occupy the typical cervical vertebra transverse foramen?
The vertebral artery, vertebral venous plexus and postganglionic sympathetic motor nerve fibers
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 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 inferior articular facet?
Forward, lateral, downward (FoLD)
What is the orientation of the typical cervical superior articular facet?
Backward, upward, medial (BUM)
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?
The spinalis cervicis, semispinalis cervicis, semispinalis thoracis, multifidis, rotators and interspinalis
