5 True/False Questions

1. Premotor Cortex → Responsible for planning and guiding movements (advanced planning of movements)

   True        False

2. Cortex → Anchors the spinal cord by a fibrous extension of the pia mater (filum terminale)

   True        False

3. Afferent (Sensory) Division → -Convey impulses from the CNS
   -Carries instructions to effector organs

   True        False

4. Multiple Sclerosis (MS) → -Immune system attacks myelin
   -Schwann cells can direct the regrowth of severed axons but oligodendrocytes cannot
   -If axons in spinal cord are severed, the neurons cannot be repaired and paralysis and loss of sensation occurs in region that had been innervated

   True        False

5. Ganglion/ganglia → A collection of neural cell bodies outside the CNS (i.e. in PNS)

   True        False
