Answer to Question 1

Ans: A
Feedback:
Neurotransmitters are referred to as first messengers, which denotes that they are molecules that communicate information or change from one cell or cell group to another, cause an immediate effect, and are typically found in circuitry that produces behavior. A second messenger is a substance manufactured from the coupling of a first messenger to a receptor. Neurotransmitters can initiate the action of second messengers but neurotransmitter themselves are not second messengers.

Answer to Question 2

Ans: C
Feedback:
Each neuron consists of a cell body with a nucleus, other organelles, and snakelike extensions called dendrites and axons that funnel information in and out. Between each neuron are spaces called synapses, which serve as points of cellular contact. Glial cells and synapses are not components of a neuron.
