Biological Bases of Behavior

What number(s) on the graph represents the Resting Potential?

• 1 and 2
• 1 and 5
• 2 and 3
• 3 and 4

a signal molecule that transmits nerve impulses across synapses

• neuron
• neurotransmitter
• nerve
• action potential

When a neuron is depolarized, what are the first channels to open?

• Sodium
• Potassium
• Calcium
• ACTH

A membrane potential becoming less negative is called

• hyperpolarization
• depolarization
• repolarization
• polarization

Autonomic life functions such as heartbeat and breathing are centred in the:

• Amygdala
• Brain Stem
• Cerebellum
• Limbic System

Part of a neuron that receives information from other neurons

• axon
• dendrites
• myelin sheath
• synapse

Excess neurotransmitters in the synapse that goes back into the presynaptic neuron.

• Resting potential
• Reuptake
• Retroactivity
• Repolarization

Which ions are involved in the electrical nerve impulse?

• Iodine and Sodium
• Potassium and Sodium
• Iron and Sodium
• Calcium and Iodine

The area of the brain most associated with coordination and balance is the:

• Cerebellum
• Hippocampus
• Amygdala
• Pons

The neurotransmitter most associated with rewards and motivation is:

• Dopamine
• Serotonin
• GABA
• Adrenaline
