Kyphotic and lordotic curves of the spine are positioned in the transversal plane and scoliotic curvatures in the frontal plane.TrueFalse2. In the fetal stage the entire vertebral column is scoliotic.TrueFalse3. The kyphotic and lordotic curves of the spine are the result of the wedge shaped thoracic vertebrae and the wedge shaped lumbar and cervical intervertebral discs.TrueFalse4. In general a backward tilt of the pelvis flattens the curves of the spine (in the sagittal plane) and a forward tilt of the pelvis deepends the curves.TrueFalse5. The lumbar vertebrae possess foramina transversaria and the thoracic vertebrae possess foveae costaeTrueFalse6. Seen from above, the body of a thoracic vertebra is rectangular and the foramen vertebrale is triangular.TrueFalse7. Uncovertebral joints are mostly present at the upper and lower sides of the corners of the bodies of the cervical spine.TrueFalse8. The spinous and transversal processes of the cervical vertebrae are pointing rather horizontally and are bifid.TrueFalse9. The main parts of the atlas are the anterior arch, the massae laterales, and the posterior arch.TrueFalse10. The articular facet for the dens axis (fovea dentis) is positioned at the dorsal side of the anterior arch of the atlas.TrueFalse11. Ventrally and dorsally to the large vertebral foramen of the axis lie the lateral masses.TrueFalse12. On the caudal side of its body, the axis carries the dens axis, which endes in a rounded point: the apex dentis.TrueFalse13. In the case of spina bifida there is an absent or incomplete vetebral arch.TrueFalse14. The longitudinal rotational axis of a thoracic vertebra runs through the middle of the body of this vertebra.TrueFalse15. The longitudinal rotational axis of a lumbar vertebra runs through the root of the body of the pricessus spinosis of this vertebra.TrueFalse16. The angle of the cervical articular surfaces (C3-C7) is about 45° with the horizontal plane.TrueFalse17. The upper articular surfaces of the cervical vertebrae (C3-C7) are almost flat and face dorso-cranially.TrueFalse18. The upper articular facet of a lateral mass of the atlas is concave and the lower is slightly convex.TrueFalse19. The anterior surface as well as the posterior surface of the dens of the axis possess an articular facet.TrueFalse20. The upper articular surfaces of the lumbar vertebrae are concave, have an almost vertical position, face dorso-medially and form (in the transversal plane) a part of a circle with its centre in the root of the spinous process.TrueFalse21. A vertebral unit are two subsequent vertebrae with an intervertebral disc in between.TrueFalse22. A vertebral unit composes a leversystem to relieve the intervertebral disc.TrueFalse23. The intervertebral disc is a cartilaginous joint of synchondrosis type: a lot of fibrous connective tissue with some chondral cells.TrueFalse24. The components of an intervertebral disc are the nucleus pulposis, annulus fibrosus, and cartilaginous endplates. There is no clear distinction between the nucleus and annulus.TrueFalse25. The nucleus has a small fraction of collagen fibres and a big fraction proteoglycans; the annulus has a big fraction of collagen fibres and a small fraction proteoglycans.TrueFalse26. The nucleus is very hydrofilic, the annulus is a little bit hydrofilic.TrueFalse27. The annulus is composed of two to three lamellae; within each lamella the fibres have the same obliquety.TrueFalse28.

Amongst others, the functions of an intervertebral disc are: shock absorbtion, intrinsic stability, limitation of movements and determination of the position of the axes.TrueFalse30. Aging and the decrease in quality of an intervertebral disc mostly starts with loss of proteoglycans in the nucleus and with the destruction of the collagen lattice (framework) in the nucleus.TrueFalse31. Loading (longitudinal pressure) of the spine in neutral position increases the pressure (of the nucleus) against the annulus in all directions.TrueFalse32. Loading (longitudinal pressure) of the spine in a flexed position increases the pressure (of the nucleus) against the annulus mainly in ventral direction.TrueFalse33. Loading (longitudinal pressure) of the spine in a lateral flexed position increases the pressure (of the nucleus) against the annulus mainly in heterolateral direction.TrueFalse34. The lig. longitudinale posterius connects the bodies of the vertebrae with each other and the ligg. flava connect the arches of the vertebra with each other.TrueFalse35. The lig. longitudinale anterior originates from the anterior tubucle of the atlas and extends downward along the anterior surface of the vertebral bodies.TrueFalse36. The ligg. intertransversaria connect the lateral sides of the vertebral bodies with each other.TrueFalse37. The lig. supraspinale extends between the vertebral arches, is under tension even at rest (because of its elastic fibres) and helps to keep the spine in erect position (intrinsic stability)TrueFalse38.
