How does myelination affect the signal transmission of a neuron?
a. It slows the transmission of a signal.
b. It speeds the transmission of a signal.
c. It filters the signals so that only the correct signals are sent.
d. It allows two or more signals to be transmitted simultaneously.
Question 2
In hopes of better understanding how glia affect brain repair, Dr. Jennings develops a special mouse lacking specific types of glia. In her experimental design, Dr. Jennings injures the brain of this special mouse and monitors neuronal repair. What is Dr. Jennings likely to observe?
a. Action potentials can no longer propagate in unmyelinated nerves.
b. Cell debris from damaged neurons is not cleared.
c. A blood-brain barrier is formed in response to the injury.
d. Neurons undergo hypermyelination.
