Receptors
The messages or impulses are picked up by stimuli and neurons pick up the stimuli.
Sensory nerves, or the receptor nerves, as they are only made up of sensory neurons. Receptors are the specialised structures at the end of the sensory nerves that receive the stimuli and convert it into an electrical signal to be conducted by the nerve as a nerve impulse.
Different stimuli trigger sensory nerves. Such stimuli may include temperature, pressure, vibration, touch, and pain. In answer to your question, nothing sends messages to your sensory nerves. What happens is that these nerves send signals to your brain which then interprets the signals as pain, pleasure, etc. as stated above, never receiving messages.

Brain is likened to a telephone switchboard because brain is connected to series of network that accept messages from various stimuli, after accepting the stimuli, the brain will send reflexes in accordance with the messages sent.
i actually can dectect supraliminal messages. i do it every day. i also learned i have been programed to speak in supraliminal messages. they only work on a weaker mind My answer differs from above. Subliminal messages are recorded to be inaudible and sent entirely to your subconscious mind while supraliminal mean "messages send with the speed of light" which is impossible. we can not travel with the speed of light nor we have invented speed of light recorders. Stimuli are same as subliminal "subliminal stimuli."

ThalamusIf you are referring to outside stimulus that are sensory messages, all stimuli, except smell, go to the thalamus in the brain which is then relayed to the cerebral cortex.
