Answer to Question 1

Neurotransmitters

Neurotransmitters (acetylcholine, norepinephrine, dopamine, and serotonin) function to conduct transmission between the synapses.

Answer to Question 2

ANS: B, D, E, F
As the person ages, normal age-related changes occur such as loss of neurons, reduction of cerebral blood flow, appearance of lipofuscin, a decrease in oxygen use and brain metabolism, and a decline in velocity of nerve impulses.
