Nervous System 3: The Central Nervous System


1.      Identify the components of the CNS as the brain and spinal cord

2.      Locate and outline the functions of the cerebral hemispheres, the diencephalon, the brain stem and the cerebellum

3.      Differentiate between the grey matter and white matter of the CNS and locate each within the brain and spinal cord

4.      Explain what are gyri and sulci

5.      Explain what are nuclei within the brain

6.      Explain that the cerebral cortex contains motor areas, sensory areas and association areas

7.      Locate the following motor and sensory areas and describe the role of each:

a.      Premotor cortex

b.      Primary motor area

c.      Broca’s ar

2. which is false of the cerebral hemisphere

  • divides into 5 lobes
  • the hemispheres can be divided into three portions superficial cortex: white matter, internal grey matter and the basal nuclei
  • two large fissures Longitudinal and transverse
  • obscure the diencephalon and upper brainstem
  • shallow grooves are called sulci and divide hemispheres into lobes

3. the insula is found deep to the cerbral cortex

  • True
  • False

4. basal nuclei could be expalined as islands of white matter within grey matter

  • False
  • True

5. which is true of the cerebral cortex

  • each hemisphere deals with motor and sensory functions of the ipsilateral side
  • subconcious propreoception occurs in the cerebral cortex
  • voluntary movements are initiated in the cerebral cortex
  • houses tracts
  • functionally there are three areas within the cerebral cortex motor, sensory and autonomic areas
