The Vertebral Column Flashcards
Vertebral column jobs
protect spinal cord, provide muscle attachment and structural support
Normal spinal curves
primary and secondary
primary normal curves
thoracic, sacral
thoracic curve
upper back between shoulder blades, curves out
sacral curve
butt, curves out
secondary normal curves
cervical, lumbar
cervical curve
neck, curves in
lumbar curve
lower back, curves in
primary curves develop
in utero
secondary curves develop
when you lift up your neck and sit on your butt
abnormal curves
kyphosis, lordosis, and scoliosis
kyphosis
hunchback
lordosis
swayback
scoliosis
lateral curvature
vertebra body
main bulge
spinal foramen
big giant hole
neural arch
lines spinal foramen
neural arch parts
pedicles and laminae
pedicles
2 bits opposite laminae
laminae
2 bits on inside of spinous process
spinous process
spiny bit
transverse process
side bulges
superior articulating processes
top jutty bit
inferior articulating processes
lower jutty bits
intervertebral foramen
hole formed between vertebrae when stacked
number of cervical vertebrae
7
number of thoracic vertebrae
12
number of lumbar vertebrae
5
cervical vertebrae identification
transverse foramen, small holes for arteries, feed back side of brain
1st cervical vertebrae
atlas, holds up skull, has superior and inferior articular surfaces for ondontoid process
2nd cervical vertebrae
axis, has ondontoid process (pivot point for neck)
thoracic vertebrae identification
rib facets/demifacets
Rib facets/demifacets
depressions where ribs attach
lumbar vertebrae identification
lack rib facets and transverse foramina, very, very large
sacrum
fused 5 vertebrae
coccyx
fused 3-5 vertebrae
