question 1

which chemicals allow neurons to communicate with one another?
glial transmitters
sensory transmitters
neurofibrils
neurotransmitters
question 2

in depolarization the membrane potential moves toward zero, whereas in hyperpolarization the membrane potential moves away from zero.
true
false
question 3
1 pts
there are two types of synapses—the electrical synapse and the __________ synapse.
chemical
sensory
sonic
mechanical

Explanation:

• Question 1: Neurons communicate via neurotransmitters. Glial cells support neurons but don't transmit signals between them. There's no such thing as sensory transmitters in this context, and neurofibrils are structural components of neurons, not communication - chemicals.
• Question 2: Depolarization is when the membrane potential becomes less negative (moves toward zero), and hyperpolarization is when it becomes more negative (moves away from zero).
• Question 3: The two main types of synapses are electrical and chemical. Sensory, sonic, and mechanical are not types of synapses relevant here.

Answer:

• Question 1: D. neurotransmitters
• Question 2: True
• Question 3: A. chemical
