Exam 4: The Vertebral Column
Which of the following factors is the primary contributor to the vertebral body's decreased ability to withstand compressive forces as it ages?
A
Identify the ligaments that are unique to each of the areas,including the motions each ligament checks.
(a)Thoracic region-The supraspinous ligament runs from C7 to the sacrum but blends with the insertion of the lumbar extensors.Therefore,although not really unique to the thoracic region,it is not obvious in the lumbar region and changes its name in the cervical region.The supraspinous ligament checks flexion.
(b)Lumbar region-The interspinous and intertransverse ligaments are well developed in the lumbar area only.The interspinous checks flexion,while the intertransverse ligaments are important checks to lateral flexion to the opposite side as well as to rotation in both directions.
(c)Cervical region-The alar ligaments are unique to the segments between C2 and the occiput.They are paired ligaments attached to the dens and to the foramen magnum.The alar ligaments check rotation between C1 and C2.The supraspinous ligament changes to the ligamentum nuchae,which runs from C7 to the occiput of the skull.It predominantly checks flexion.
In the cervical spine,the greatest amount of rotation is available at which of the following motion segments?
B
What parts of the typical vertebra are included in the anterior portion of the vertebra? In the posterior portion?
Which of the following abdominal muscles would be active during trunk rotation to the right?
If a person stands and bends forward while attempting to touch his or her toes (keeping knees extended),this produces ________________at the innominates,________________at the sacrum and flexion of the lumbar spine.
Which of the following statements is true concerning the surface of the sacroiliac joints?
What is the difference between the lamina and the pedicle of the vertebrae?
What is the function of lumbopelvic rhythm? To what is this analogous?
Which of the following is true with regard to the structure of the anulus fibrosis of the normal intervertebral disc?
Which of the following structures would be best suited to resist the tensile forces produced during spinal extension?
Give the new name acquired by each of the following ligaments as it passes cephalad to the axis: anterior longitudinal ligament,posterior longitudinal ligament,ligamentum flavum,and supraspinous.
Which of the following describes the lumbar spine facet joint arthrokinematic motion during (L)lateral flexion in the neutral position?
Given the vertebral structure and orientation of the facet joints in the thoracic spine,which of the following motions would be most limited?
Compare the mobility-stability of the cervical (C2 to C7)and thoracic regions,including the structures implicated.
Describe the role of the disc in compressive loading of the spine.What happens under normal circumstances? What happens when normal forces are exceeded?
If you needed to perform joint mobilization on the transverse processes of T9,you could locate them by which of the following landmarks?
Which of the following describes biochemical changes that occur in the intervertebral disc with aging?
Which of the following may contribute to a dysfunction of trunk deviation (L)with forward bending?
