Cervical region Flashcards
Which mammals have more than seven cervical vertebrae
ant bear and three toed sloth
Which mammals have less than seven cervical vertebrae
two toed sloth and manatee
Which vertebrae are typical cervicals
C3-C6
What is the appearance of the typical cervical vertebral body from the lateral view
posterior hight is higher than anterior hight by a few millimeters
What would be the direction of the cervical curve based on osseous features
posterior or kyphotic
What accounts for the direction of the typical cervical curve
the intervertebral disc hight
What is the direction of the typical cervical curve
anterior or lordotic
at which vertebral couple will the cervical curve again increase intervertebral disc height
C5/C6
What is the effect of aging on the cervical vertebral body
it diminishes the overall height of the vertebral body
What are the modifications of the superior epiphyseal rim of a typical cervical
anterior groove, posterior groove, right and left uncinate processes
What are the names of the lateral modifications of the superior epiphyseal rim
uncinate/unciform/uncovertebral process or uncus or lateral lip
at what developmental age will the uncinate process first be observed
3rd or 4th fetal month
What are the modifications of the inferior epiphyseal rim of a typical cervical
anterior and posterior lip and right and left lateral grooves
What is the joint classification for the anterior lip-anterior groove articulaton
fibrous (amphiarthrosis) syndesmosis
What is the joint classification for the uncinate process-lateral groove articulation
modified synovial saddle (diarthrosis sellar)
What is the joint classification for the spongy bone intervertebral disc articulation
cartilaginous (amphiarthrosis) symphisis
How many joint surfaces are present on the upper surface of a typical cervical vertebral body
5
how many joint surfaces are present on the vertebral body of a typical cervical
10
What is the name given to the uncinate process-lateral groove articulation
joint of luschka or uncovertebral joint
the joint of luschka is formed by what two surfaces
uncinate process and lateral groove
What is the functional significance of the joint of luschka
it appears to stabilize the intervertebral disc while accommodating flexion-extention and requiring coupled motion (axial rotation and lateral bending) in the cervical spine
What muscle attaches to the typical cervical vertebral body
longus colli muscle
What is the orientation and angulation of the pedicle of a typical cervical
posterolateral, 45 degrees
at what location on the vertebral body of a typical cervical will the pedicle attach
to the side and in the center of the vertebral body
What surface feature is located at the upper margin of the pedicle
superior vertebral notch
What ligament attaches to the lamina of a typical cervical
ligamentum flavum
What joint classification will be associated with the ligamentum flavum and its attachment
fibrous (amphiarthrosis) syndesmosis
Ossification of the ligamentum flavum at the attachment site on the lamina will result in what feature
para articular process
What is the outline of the vertebral foramen of a typical cervical vertebral foramen
heart shaped or triangular
Which is the greatest diameter of the vertebral foramen of a typical cervical foramen
transverse
What soft tissue diameter mimics the outline of the typical cervical vertebral foramen
the transverse diameter of the cervical enlargement of the spinal cord
the greatest transverse diameter of the typical cervical vertebra occurs at what level
C6
the greatest frequency of osteophytes associated with the vertebral body occurs at which typical cervical vertebral couple
C5/C6
