Question

Quizplus · Accepted Answer

The substantia gelatinosa is a structure in the spinal cord that plays a key role in modulating sensory input, particularly pain. It receives input from both primary and secondary afferents and is involved in gating pain signals before they are transmitted to higher brain regions. The other options listed - primary afferents, secondary afferents, and the spinothalamic tract - are involved in conveying sensory information to the brain but do not have as direct a role in modulating or filtering this information.
