ap vertebral column

ap vertebral column
first cervical vertebra

carries the skull on its articular facets
second cervical vertebra

it has a process that extends superiorly from the vertebral body
body of the vertebrae
cervical 7, thoracic 12, lumbar 5, 5 fused to sacrum & 4 fused to coccyx=total of 33
intervertebral disk
between each body in the vertebrae is a disk of cartilage
intervertebral foremina
an opeing btw the pedicles of adjacent vertebrae
transverse process
a lateral process that extends from the junction of the pedicle & lamina of the vertebrae

site for muscle attachment

on the thoracic vertebrae there is an articular surface for ribs
is a plate of bone that is an extension of the pedicle. located btw the transverse process & the spinous process of the vertebrae
a bony projection that extends posteriorly from each side of the vertebral body. connects the body w/the transverse process
most inferior portion of the vertebral column. formed by fusion of 4 coccygeal vertebrae. articulates superiorly w/sacrum
a triangular bone that is formed by 5 fused vertebrae.sacrum & 2 oscoxae form pelvis. articulates with these bones at the sacroiliac joint. forms the posterior part of the pelvis
transverse foramina/foramen
cervical vertebrae have these. these are openings in each transverse process. allow for passage of the vertebral arteries
spinous process of vertebrae
a posterior process of the vertebrae that protrudes midline and projects inferiorly. important site of muscle attachment.
spinal (vertebral) foramen
is the opening formed by the body & the vertebral arch of the cervical, thoracic & lumbar vertebrae. contains spinal cord, meninges, epidural fat & blood vessels

big opening
neural arch
the curve of bone formed by the pedicle and lamina of the vertebrae
odontoid process/dens
a process that extends superiorly from the vertebral body of the axis (2nd cervical vertebrae)
