what vertebrae is this?
lordosis
abnormal anterior curvature of the lumbar spine (sway-back condition)
scoliosis
abnormal lateral curvature of the spine
dens
acts as a pivot point; allows you to shake your head no; cranial extension of the body; most distinctive feature of c2
vertebral arch
arch formed from the joinng of all posterior extensions; joins the laminae and pedicles from the vertebral body
transverse process (thoracic)
articulates with the superior articular process of the vertebra directly inferior
anterior tubercle of the atlas
bump on the anterior arch
Vertebral foramen
canal through which the spinal chord passes
inferior articulating process (lumbar)
directed laterally to the vertebrae below it, more narrow
superior articulating facet (lumbar)
directed medially to the vertebrae above it, wide
no
does the altas have a body?
kyphosis
exaggerated posterior curvature of the thoracic spine that causes significant back pain and limited mobility
inferior articular process (cervical)
flat, medium sized; projects downwards and touches the process of the vertebrae below it
laminae
flattened roof plates that complete the arch posteriorly
vertebral foramen
for the passage of spinal nerves
vertebral arch (lumbar)
formed by the fusion of pedicles and lamina
superior articular facet
fused with and projects superiorly from the junction of the pedicles and the laminae
intervertebral foramen
gaps formed between the vertebrae when they're stacked; where the nerves branch out from
transverse foramen
holes in the transverese process
inferior articular facets
inferior facets directed anteriolaterally
body of the lumbar
larger than the bodies of the cervical vertebrae; also called the centrum; massive, kidney shaped
intervetebral foramen (thoracic)
lateral opening between adjacent vertebrae, where nerves branch out from, circuar
transverse process (cervical)
lateral projections from the vertebral arch
spinous process of the axis
long; sharp; projects inferiorly; slightly fork shaped
lateral masses vertebrae
most bulky and solid portions supporting the weight of the head
superior and inferior articular facets
near the superior and inferior borders of the body, for the attachment of the head of the rib
inferior articular process (thoracic)
projects laterally from each side of he vertebral arch
superior articular process (cervical)
projects upward from one vertebra and meets a similar pair of processes that projects downward from the vertebra above
spinous process (lumbar)
short, blunt projects directly posteriorly
pedicles
short, bony cylinders that project posteriorly from the vetebral body
spinous process
single posterior projection arising at the junction of the two laminae
spinous process (cervical)
single projection arising from the posterior aspect of the vertebral arch (the fused laminae), forked tongue shape- bifid
body of the axis
smaller than the bodies of other vertebrae
pedicle (lumbar)
stretch of bone between the body and the srticulating facets
superior articular facets
superior facets directed posteromedially
lumbar centrum
thick oval part of the vertebrae
transverse process (lumbar)
thin and tapered; projects laterally from each side of the vrtebrae
vertebral foramen (lumbar)
triangular hole in the vertebrae through which nerves pass
transverse process
two lateral projections from the vertebral arch
