HOSA BEHAVIORAL HEALTH
QUESTIONS WITH 100%
CORRECT SOLUTIONS.
Sensory receptors - answer -sensory nerve ending that responds
to a stimulus in the internal or external environment of an
organism
Neuron - answer -a specialized cell transmitting nerve impulses; a
nerve cell
Sensory neurons - answer -a neuron conducting impulses
inwards to the brain or spinal cord
Motor neurons - answer -a nerve cell forming part of a pathway
along which impulses pass from the brain or spinal cord to a
muscle or gland
Interneurons - answer -a neuron that transmits impulses between
other neurons, especially as part of a reflex arc
Synapse - answer -a junction between two nerve cells, consisting
of a minute gap across which impulses pass by diffusion of a
neurotransmitter

,Dendrite (receive) - answer -a short branched extension of a
nerve cell, along which impulses received from other cells at
synapses are transmitted to the cell body.
Axon (relay) - answer -the long threadlike part of a nerve cell
along which impulses are conducted from the cell body to other
cells
Myelin sheath - answer -a fatty white substance that surrounds
the axon of some nerve cells, forming an electrically insulating
layer
Action potential - answer -a neural impulse; a brief electrical
charge that travels down an axon. The action potential is
generated by the movement of positively charged atoms in and
out of channels in the axon's membrane.
Threshold - answer -The level of stimulation required to trigger a
neural impulse
Neurotransmitter - answer -a chemical substance that is released
at the end of a nerve fiber by the arrival of a nerve impulse and,
by diffusing across the synapse or junction, causes the transfer of
the impulse to another nerve fiber, a muscle fiber, or some other
structure.
Endorphins - answer -a natural, opiate-like neurotransmitters
linked to pain control and to pleasure.

, Dopamine - answer -a neurotransmitter associated with
movement, attention and learning and the brain's pleasure and
reward system
Seratonin - answer -a neurotransmitter that regulates mood,
appetite, sleep, muscle contraction, and some cognitive functions
including memory and learning. Lack of this can cause
depression.
Acetylcholine - answer -a neurotransmitter that enables learning
and memory and also triggers muscle contraction
Norepinephrine - answer -a hormone that is released by the
adrenal medulla and by the sympathetic nerves and functions as
a neurotransmitter. It is also used as a drug to raise blood
pressure
Gamma-amino Butyric acid (GABA) - answer -is an amino acid
which acts as a neurotransmitter in the central nervous system. It
inhibits nerve transmission in the brain, calming nervous activity
Glutamate - answer -major excitatory neurotransmitter involved in
memory. An excess can cause migraines or seizures
Reuptake - answer -a neurotransmitter's re-absorption of the
sending neuron
