Spine Quiz

Cresent shaped annulus

Kidney shaped vertebral body

Adjacent vertebrae articulate via the uncovertebral joint

Disc is divided by the uncovertebral cleft

Posterior annulus is thin walled

Cresent shaped annulus that becomes thinner laterally

Lower water content than the thoracic or lumbar disc

The nucleus is highly vascular and innervated

An uncovertberal cleft can be identified that advances to divded the disc by age 14

Disc prolapse rarely occurs posteriorlaterally

Nuscleus pulposis

Annulus fibrosus

Ligamentum flavum

Posterior longditudinal ligament

Interspinous ligament

Oval shaped end plates that curl up at the lateral edges

Paired uncinate processes which guide movement

Triangular shaped vertebral foramen

Transverse processes have 2 tubercles for muscle attachment

Foramen transversarium through which passes the vertebral artery at all levels

Originates on the transverse processes of T1-C2

Line of action produces lateral flexion

All fibres are innervates by the posterior primary rami

Anteriolateral fibres are innervated by the anterior rami

Inserts onto the tubercle of the superior transverse process

45 degrees to the sagittal plane

60 degrees to the sagittal plane

90 degrees to the sagittal plane

0 degrees to the frontal plane

45 degrees to the frontal plane

Outer 1/3 of the annulus

Periosteum of teh spinous process

Zygapophyeseal joints

Posterior lumbar musculature

Skin over the vertebrae

Innervated by the ventral rami C2-6

Inserts onto the transverse processes of C3-C5

Inferior fibres originate at vertebral bodies of C5-T3

Inserts onto the transverse processes of C1-3

Superior fibres originate on transverse processes of C3-6

Vertebral end plates

Zygapophseal joints

Fibres of multifidus

Outer 1/3 of the disc

Nucleus pulposis

Sypathetic ganglion

Gray ramus communicans

Recurrent meningeal

Ventral ramus

Dorsal root ganglion
