Vertebral Column Flashcards
Point where 2 laminae Meet posteriorly
Spinous Process
Point where pedicle meets lamina more posteriorly
transverse process
Points at which the lamina meets the pedicle
- superior articular process
- inferior articular process
- Transverse process
Space through which spinal nerves exit vertebral canal laterally
intervertebral foramen
two sections which make up the intervertebral foramina
superior vertebral notch and inferior vertebral notch
Cervical vertebrae 1
atlas
Cervical vertebrae 2
axis
the projecting part from the body of the axis, in which the atlas rotates
dens
how to identify a cervical vertebrae
Bifid spinous process
or foraman of the transverse process
what are on the thoracic vertebrae that allow for the ribs to attach
facets
where does the facet for the head of the rib go
on the facet on the body of the thoracic vertebrae
where is the facet for the tubercle of the rib located
on the transverse process of the thoracic vertebral arch
from medial to lateral the sacral crests
median sacral crest, intermediate sacral crest, lateral sacral crest
what ligament limits extension of the vertebral column
anterior longitudinal ligament
what ligament prevents hyperflextion of vertebral column
posterior longitudinal ligament
point of the intervertebral discs
- strong attachment
- permit movement between adjacent vertebral bodies
what is the name of the joint that is between the superior and inferior articular processes
zygapophysial joint
what does the zygapophysial joint allow
allows gliding movements between articular processes
ligaments that strengthen the stability between the arches
interspinous ligament
supraspinous ligament
intertransverse ligament
assists in cervical extension of supraspinous ligament
ligamentum nuchae
what ligament joins the laminae of adjacent vertebrae
ligamentum flava
what direction do the spinal nerves exit out of the anterior intervertebral foramina
anteriorly and posteriorly
what are foramina of the sacrum
anterior intervertebral foramina and posterior intervertebral foramina
- sacral canal
opening at the end of the sacral
sacral hiatus and sacra cornu
why is their an opening at the bottom of the sacral
lack of spinous process lamina possible articular
what does the ligamentum nuchae do
cervical extension of supraspinous ligament
what does the ligamentum flava do
joins laminae of adjacent vertebrae
