◉ pain perception.
Answer: neurologic experience of pain
◉ somatic nervous system.
Answer: controls body's voluntary and reflex activities through
somatic sensory and somatic motor components
◉ efferent division.
Answer: consist of all outgoing information along motor and efferent
pathways
◉ afferent division.
Answer: consist of all incoming information traveling along sensory
and afferent pathways
◉ pain control.
Answer: mechanism that alleviates pain
, ◉ pain threshold.
Answer: to the point at which sensation starts to be painful and
discomfort results
◉ half-life.
Answer: period of time it takes for 50% of the drug to be
metabolized/removed from the body
◉ repolarization.
Answer: occurs once the peak of action potential is reached and the
membrane potential begins to move back toward the resting
potential
◉ polarization.
Answer: (resting state) means that electrical charge on the outside
of the membrane is positive while the electrical charge on the inside
of membrane is negitive
◉ saltatory conduction.
Answer: propagation of action potentials along myelinated axons
from one node of ranvier to the next node
