thoracic

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
