1. What are the functions of the frontal lobe?: Voluntary motor
functions, motivation, foresight, planning, memory, mood, emotion,
social judgement, and aggression
2. Parietal lobe: - Between central sulcus and paerieto-occipital
sulcus
- Integrates general senses, taste, and some visual information
3. Occipital lobe: - Caudal to parieto-occipital sulcus
- Primary visual center of brain
4. What does gray matter contain?: Cell bodies, dendrites,
and synapses
5. Why does gray matter have a darker color?: Due to very
little myelin present in tissue
BIO 201
,6. Where is gray matter located in the brain?: Forms the
surface layer (cortex) over the cerebrum and cerebellum. It is found
in cerebral cortex, basal nuclei, and the limbic system
7. What structures does gray matter form deep within the
brain?: Nuclei
8. What is the primary function of gray matter?: Site of
processing and synaptic integration
9. What are bundles of axons in the nervous system
called?: White matter
10. What gives white matter its white color?: Lots of myelin
11. What are bundles of axons called in the CNS?: Tracts
12. What are bundles of axons called in the PNS?: Nerves
13. Where is white matter located in relation to cortical gray
matter in the brain?: Deep to cortical gray matter
14. Where is white matter located in relation to gray matter
in the spinal cord?: Superficial to gray matter

15. What makes up most of the volume of the cerebrum?:
White matter
16. Tracts: Bundles of nerve fibers in the central nervous
system
17. What are the three types of tracts?: projection tracts,
commissural tracts, association tracts
18. Function of white matter: carry signals from one part of
CNS to another
19. Content of cerebral cortex: stellate cells and pyramidal
cells
