EXAM 2: REGIONS - cervical region Flashcards
(26 cards)
Which mammals have more than seven cervical vertebrae?
ant bear, three toed sloth
Which mammals have less than seven cervical vertebrae
two toed sloth, manatee
Which vertabrae are typical cervicals
C3-C6
Which vertebrae are atypical cervicals
C1, C2, C7
What is the appearance of the typical cervical vertebral body from the lateral view?
posterior height is greater than anterior height 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 height
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 modification of the superior epiphyseal rim
uncinate process, unciform process, uncovertebral process, uncus or lateral lip
at what developmental age will the uncinate process first be discovered
3-4 fetal month
what are the modifications of the inferior epiphyseal rim of a typical cervical
anterior lip, posterior lip, right and left lateral grooves
what is the joint classification for the anterior lip anterior groove articulation
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) symphysis
how many joints are present on the lower surface of a typical cervical body
five
how many joint surfaces are present on the vertebral body of a typical cervical
ten
how many synovial joint surfaces are present on the vertebral body of a typical cervical
four
The joint of Luschka is formed from what surfaces
the uncinate process and lateral grooves
what is the functional significance of the joint of Luschka
it appears to stabilize the intervertebral disc while accommodating flexion - extension and requiring coupled motion (axial rotation with lateral bending) in the cervical spine
what muscle attaches to the typical cervical vertebral body
the longus colli muscle
What soft tissue diameter mimics the outline of the typical cervical vertebral foramen
the transverse diameter of the cervical enlargement of the spinal cord
