Which portion (s) of a neuron is (are) likely to be associated with a sensory receptor or sensory organ?

dendrites

Explanation:

The sensory neuron has two processes, a dendron that transmits impulse from the sensory ends to the cell body and an axon that transmits impulse from the cell body to the CNS. The axon process terminates into synaptic knobs. Dendrites are projections of a neuron that receive signals from other neurons.
