Atypical C7 characteristics
Has a vertebra prominens which is easily palpatable and extends over T1
Best motion of Cervical vertebra
Thoracic vertebrae characteristics
long sloping spines over inferior vertb.
Facets on T2-T8 for articulation with ribs; small cavities on pedicles.
Best motion of Thoracic vertebrae
Lateral flexion
Characteristics of Lumbar vertebrae
And Best Motion
Parts are large and thick, bear weight.
Very blunt spinous processes

Bending at the waist is really
Bending at the lumbar
characteristics of saccral vertebrae
Fused; has no motion.
ARticulates with ilium
Fused, has no motion.
Vertebral column bones
33 bones total:
7 Cervical Vertebrae
12 Thoracic
5 Lumbar
5 Sacral (fused)
4 Coxxygeal (fused)
dense portion of the vertebra, ventral to everything
side of vertebral foramen, between the body and the transverse process
transverse process
pokes out of side of vertebrae from posterior view
between transverse and spinous processes
spinous process
sticks out of very back of vertebrae
vertebral foramen
hole through which the spinal cord runs, created by the pedicle, body, and articular processes
articular processes with facet
inferior articulates with the superior facet of vertebra below it, superior articulates with inferior of vertebra above it. situated just posterior to the vertebral foramen. forms a small gliding joint
Facet joints of vertebrae
Gliding; allows flexion, extension, rotation depending on region. Formed between articulations between adjacent vertebrae.
Anterior longitudinal ligament
ventral to the bodies of vertebrae; prevents extensive extension; backbending backwards.
posterior longitudinal ligament
forms the anterior spinal canal wall (behind the spinous processes and cord) prevents bending forward, flexion
supraspinous ligament
super spine; runs along tips of spinous processi, prevents flexion bending forward
ligamentum nuchae
special part of supraspinous ligament
interspinous ligament
between the spinous processi; prevents flexion of spine
ligamenta flava
connect the laminae; evidently makes the posterior wall of the spinal canal
anterior/posterior sacroiliac ligaments
run between the saccrum and ilium articulations
sacrospinous greater/lesser sciatic foramen
allows the sciatic nerve to pass between the saccrum and ilium, at the greater and lesser sciatic notches.
intervertebral foramen
openings between vertebrae through which spinal nerves emerge
curvature of spine when convexity is posterior; hunchback
curvature of spine when convexity is anterior; swayback
primary curvature
present at birth, 2 curves, both are kyphosis; posterior
secondary curvature
develops in infancy, both are a lordosis
abnormal curvatures
exaggerated kyphosis-hunchback, lordosis-swayback, lateral-scoliosis
Typical cervical vertebrae - #'s/characteristic
C3-C6; transverse foramina allows passage of artery to brain to pass through. have bifid spine with 2 headed spines.
Atypical cervical vertebrae
C1, C2, C7
Atypical C1 characteristics
Atlas: no body or spine, but has cavities for occipital condyles and articulation with head.
Atypical C2 characteristics
Axis: has a dens, dontoid process. Creates a pivot joint for rotation of head
