Chapter 01

1. Dendrites contain the nuclei, ribosomes, mitochondria, and other structures found in most cells.
a. True
b. False
ANS>> False

2. Neurons receive information and transmit it to other cells.
a. True
b. False
ANS>> True

3. Santiago Ramón y Cajal used special staining techniques to reveal that the brain is composed of individual cells.
a. True
b. False
ANS>> True

4. An efferent axon carries information away from a structure.
a. True
b. False
ANS>> True

5. The greater the surface area of a dendrite, the more information it can receive from other neurons.
a. True
b. False
ANS>> True

6. Neurons are distinguished from other cells by their shape.
a. True
b. False
ANS>> True

7. The role of glial cells is to act like “glue” or scaffolding to support the neurons.
a. True
b. False
ANS>> False

8. Glial cells transmit information across long distances.
a. True
b. False
ANS>> False

9. There are two types of glial cells that produce myelin sheath. In the central nervous system, Schwann cells fulfill this role and, in
the periphery, oligodendrocytes produce it.
