1. What are amino acids?
Answer: Building blocks of proteins
2. What is glucose?
Answer: The form of sugar that circulates in the blood and
provides the major source of energy for body tissues. When its
level is low, we feel hunger.
3. What is glycogen?
Answer: An extensively branched glucose storage polysaccharide

by electrodes placed on the scalp.
5. What are the supporting cells of the nervous system called?
Answer: Neuroglial cells (glial cells)
6. What are oligodendrocytes?
Answer: Type of glial cell in the CNS that wrap axons in a myelin
sheath.
7. What is the communication pathway of neurons?
Answer: Dendrites → Soma → Axon → Terminal Buttons →
Synapse → Dendrites (etc.)
8. What is aphasia?
Answer: Impairment of language, usually caused by left

and learning, and the brain's pleasure and reward system.
13. What is GABA?
, Answer: An inhibitory neurotransmitter in the brain.
14. What is glutamate?
Answer: A major excitatory neurotransmitter; involved in memory.
15. What is histamine?
Answer: A compound that is released by cells in response to
injury and in allergic and inflammatory reactions, causing
contraction of smooth muscle and dilation of capillaries.
16. What are the two main divisions of the nervous system?
Answer: Central Nervous System (CNS) and Peripheral Nervous
System (PNS)
17. What does the CNS consist of?
