  • The posterior column neurons decussate at what level?

    1. *At the medulla

    2. At the midbrain

    3. At the pons

    4. At the thalamus

    5. Within one or two levels after entering the spinal cord

  • The lateral corticospinal tract decussates at what level?

    1. *At the junction of the medulla and the spinal cord

    2. At the junction of the midbrain and the medulla

    3. At the junction of the pons and the medulla

    4. At the thalamus

    4. Dislocation of the head of the humerus

    5. Aneurysm of the subclavian artery

  • The most prominent areas of degeneration with Friedreich's disease are in the

    1. Cerebellar cortex

    2. Inferior olivary nuclei

    3. Anterior horns of the spinal cord

    4. *Spinocerebellar tracts

    5. Spinothalamic tracts

  • Acute herniation of an intervertebral disk will require emergency surgery if

    1. The disk is laterally herniated at C7

    3. Proprioceptive system

    4. Spinothalamic tract

    5. Visual system

  • With regard to the Glasgow Coma Scale:

    1. The review of the head CT is essential.

    2. The minimum value is zero.

    3. *A score of 8 or less indicates a severe head injury.
