    The anulus fibrosus is the central region on an intervertebral disk.

    • True

    • False

    Correct Answer

  • 3. 

    The atlanto-occipital joint allows "yes,yes" movement

    • True

    • False

    Correct Answer
    A. True
    Explanation
    atlantoaxial allows "no,no" movement

    Rate this question:

  • 4. 

    There are 7 pairs of cervical spinal nerves. 

    • True

    • False

    Correct Answer
    A. False
    Explanation
    there are 8 pairs of spinal nerves and 7 cervical vertebrae

    Rate this question:

  • 5. 

    The primary curvature of the spine is developed post birth.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    the primary curvature is developed in the fetus

    Rate this question:

  • 6. 

    Which two are the most mobile regions of the spine?

    • Cervical, thoracic

    • Lumbar,thoracic

    • Lumbar, cervical

    • Cervical, sacral

    Correct Answer
    A. Lumbar, cervical
    Explanation
    The lumbar and cervical regions are the most mobile regions of the spine. The lumbar region, located in the lower back, allows for a significant range of motion and flexibility. It supports the weight of the upper body and provides stability during activities such as bending, twisting, and lifting. The cervical region, located in the neck, is also highly mobile and allows for a wide range of motion in all directions. It supports the head and allows for movements such as nodding, rotating, and tilting.

  • 7. 

    Which do not have intervertebral disks? (select 2)

    • C1/C2

    • L1/L2

    • Sacral

    • C7

    Correct Answer(s)
    A. C1/C2
    A. Sacral
    Explanation
    C1/C2 and sacral do not have intervertebral disks. The intervertebral disks are located between the vertebrae in the spine, acting as shock absorbers and allowing for flexibility. C1/C2 refers to the first and second cervical vertebrae, which are responsible for supporting the head. These vertebrae do not have intervertebral disks as their main function is to provide stability rather than flexibility. The sacral region refers to the lower part of the spine, which is made up of fused vertebrae. As a result of fusion, there are no intervertebral disks present in this region.

  • 8. 

    Which ligament is a continuation of the ligamentum nuchae? 

    • Supraspinous ligament

    • Posterior longitudinal ligament

    • Anterior longitudinal ligament

    • Ligmenta Flava

    Correct Answer
    A. Supraspinous ligament
    Explanation
    The ligamentum nuchae is a strong fibrous structure that runs along the back of the neck and connects the base of the skull to the spinous processes of the cervical vertebrae. The supraspinous ligament is a continuation of the ligamentum nuchae in the thoracic and lumbar regions of the spine. It runs along the posterior aspect of the vertebral bodies and helps to stabilize the spine. Therefore, the supraspinous ligament is the correct answer as it is a continuation of the ligamentum nuchae.

    Rate this question:

  • 9. 

    Which of the following injuries can cause neurological defects?

    • Atlanto-occipital dislocation

    • Atlantoaxial subluxation

    • Dens fracture

    Correct Answer
    A. Dens fracture
    Explanation
    A dens fracture is a type of injury that occurs in the neck, specifically in the dens, which is a bony projection at the second cervical vertebra (C2). This injury can cause neurological defects because the dens is located near the spinal cord, and any damage to the dens can potentially compress or injure the spinal cord. This can result in neurological symptoms such as weakness, numbness, or paralysis in the body parts supplied by the affected nerves. Therefore, a dens fracture can cause neurological defects.

    Rate this question:

  • 10. 

    Which stabilizing ligament connects the dens to the occipital condyles?

    • Apical ligament

    • Cruciate ligament

    • Alar ligament

    • Tectorial membrane

    Correct Answer
    A. Alar ligament
    Explanation
    apical- dens/occipital bone; alar- dens/occipital condyles ; cruciate- dens/lateral mass atlas; tectorial membrane- body axis/foramen magnum

    Rate this question:

  • 11. 

    The sacral cornuae which contains the filum terminale externum is the termination of the sacral canal. 

    • True

    • False

    Correct Answer
    A. False
    Explanation
    sacral hiatus is the end of sacral canal and also contains the filum terminale externum.
