Item #10 of 10

a mechanism similar to that proposed by the gate-control theory;

all of the alternatives are correct;

CORRECT - Yes, the blocking of pain transmission may be mediated by endorphin neurotransmitters that act via a pathway descending from the midbrain using a mechanism similar to that proposed for the gate-control theory.
