Stimulation of a sensory nerve occurs at a:

A) tract.
B) neuroglia.
C) receptor.
D) synapse.

Stimulation of a sensory nerve occurs at a receptor, which is a specialized cell or group of cells in a sensory organ that responds to a specific type of sensory stimulation. Tracts refer to bundles of axons that connect different regions of the nervous system, neuroglia are non-neuronal cells that support and protect neurons, and synapses are the junctions between two neurons or between a neuron and a target cell where communication occurs.
