It plays a role in tying reward with movement.
It is produced in the substantia nigra and released in the basal ganglia.
Which of the following are NOT one of the three steps in neurotransmission?
The halting of neurotransmission by either chemical breakdown or reuptake
The neuron entering into the absolute refractory period
The release of neurotransmitter from the axon terminal into synaptic cleft
The binding of the neurotransmitter to its receptor site
Which of the following is true regarding endorphins?

They play a specialized role in pain reduction
All of the above
During the action potential,
positive charge flows into the cell membrane.
negative charge flows into the cell membrane.
none of the above.
the membrane becomes uncharged.
Which statement best describes the absolute refractory period?
It is a brief period of time after the action potential when the neuron continually fires.
It is the optimum maximum firing rate for a neuron.
It is a brief period of time after the action potential where another action potential cannot occur.
It is a permanent state where the neuron can no longer produce an action potential after an action potential has occurred.
Which of the following best describes plasticity?
One's genetic makeup
The nervous system’s ability to change
Changes in brain size

What are the two components of the peripheral nervous system (PNS)?

What is the primary role of the hypothalamus?
Regulate sleep and wake cycles
Oversee the endocrine and autonomic nervous system
Oversee the functions of the somatosensory cortex
Regulate fear conditioning
If you remove the amygdala from the human brain, which behavior(s) would you expect to be absent?
All of the above
The medulla is responsible for
regulating sleep and wake functions.
linguistic and visuospatial abilities.
regulating breathing and heartbeat functions.
The brain stem consists of

the forebrain, hindbrain, midbrain, and association cortex.
the thalamus, midbrain and hindbrain.
the diencephalons, telecephalon, mesecephalon, and metacephalon.
Which of the following is the best possible explanation of why we lose our appetite when we are nervous?
Our parasympathetic nervous system becomes activated, thus inactivating digestion.
Our pituitary gland signals to the stomach that the body is undergoing hormonal change.
Our hippocampus becomes activated and inhibits stomach contraction.
