The function of dendrites is to
a. receive incoming signals from other neurons
b. release neurotransmitters into the spatial junctions between neurons
c. coordinate the activation of the parasympathetic and sympathetic nervous systems
d. control pain through the release of opiate-like chemicals into the brain
e. transmit signals to other neurons - receive incoming signals from other neurons
A brief electrical charge that travels down the axon of a neuron is called the
a. synapse
b. agonist
c. action potential
d. myelin sheath
e. refractory period - action potential
The slowdown of neural communication in multiple sclerosis involves a degeneration of
the
a. thresholds
b. dendrites
c. endocrine gland
d. myelin sheath
e. pituitary gland - myelin sheath
Increasing excitatory signals above the threshold for neural activation will not affect the
intensity of an action potential. This indicates that a neuron's reaction is
, a. inhibited by the myelin sheath
b. delayed by the refractory period
c. an all-or-none response
d. dependent on neurotransmitter molecules
e. primarily electrical rather than chemical - an all-or-none response
Reuptake refers to the
a. movement of neurotransmitter molecules across a synaptic gap
b. release of hormones into the blood stream
c. inflow of positively charged ions through an axon membrane
d. reabsorption of excess neurotransmitter molecules by sending neuron
e. the ending of the refractory period - reabsorption of excess neurotransmitter
molecules by a sending neuron
When the release of ACh is blocked, the result is
a. depression
b. musular paralysis
c. aggression
d. schizophrenia
e. euphoria - muscular paralysis
Opiate drugs occupy the same receptor sites as
a. acetylcholine
b. serotonin
c. endorphins
d. dopamine
e. epinephrine - endorphins
An under supply of serotonin is most closely linked to
a. Alzheimer's disease
b. schizophrenia
c. Parkinson's disease
d. depression
e. euphoria - depression
Some opiate drugs have molecular structures so similar to endorphins that they mimic
endorphin's euphoric effects in the brain, making these opiate drugs which kind of
molecule?
a. agonists
b. antagonists
c. endorphins
