practical one -axial skeleton except skull Flashcards
intervertebral foramina
the foramina near the connection of each vertebrea
intervertebral discs
cushion/cartilage between each vertebra
vertebral canal
runs through back on each vertebrae, they connect making a canal down the spine. the intravertebral foramina goes through these perpendicularl
body of vertebra
the solid part on the anteror side of each vertebra, separated by intervertebral discs
vertebral arch
contains lamina and pedicle, the anterior of the vertebral foramen
pedicle
on eaither lateral side of the vertabral foramen, part of the vertebral arch
lamina
connect the pedicle to the spinal process
vertebral foramen
large hole in vertebra that when connected together with other vertebrae for the vertebral canal
spinous process
the process on the very anterior of each vertebrae
transverse process
the processes on eather side of the spinous process on the vertebra,
superior articular facet
facet on the external part of each process
superior articular process
connects to the inferior process on the vertrabra above it. process on the outside of each superior articular facet, connected to pedice that connects to body
inferior articular process
connects to superior process on below vertebra. less wide than the superior.
inferior articular facet
flat part of process that connects to greater articular facet of below vertebra
transverse foramen of cervical vertebra
DISTINGUISHING FEATURE OF THIS VERTEBRA. two holes on either side of vertebral body
atlas
part of cervical vertebra. very top, connects to skull
axis
second vertebra, under atlas. less wide
dens
“tooth of the axis” process sticking out of atlas. connects to atlas
vertebra prominens

manubrium (and its components)
top of anterior sternum. triangular.
suprasternal notch
clavicular notch
costal notch
suprasternal notch
notch on top of manubrium
clavicular notch
notch on either side of suprasternal notch
costal notch
notch on very side of manubrium
body of sternum (and its parts)
middle of sternum above xiphoid process and below manubrium
sternal angle and costal notch
sternal angle
angle separating sternum from manubrium
costal notch
6 of these. notches on both sides of body of sternum
xiphoid process of sternum
small area below sternum
RIBS (how many pairs)

artiuculates with vertebral column
tubercle of ribs
in between the head and the angle, has an articular facet for the transverse process attached
neck
in between the tubercle and head
shaft of ribs
middle of long part of bone
costal groove of ribs
upper end of long part of rib boen
costal cartilages
cartilage that connects rib to sternum
