It seems like you’re listing terms that are related to communication in the nervous system. Would you like any specific information or explanations about these terms? Here is a brief overview:
-
Messages: In a biological context, these typically refer to the information transmitted between different cells, particularly nerve cells (neurons), which communicate through electrical and chemical signals.
-
Signals: Referring to the electrical impulses (action potentials) generated by neurons when they receive stimuli. These signals travel along the neurons to relay information to other neurons, muscles, or glands.
-
Nerves: Bundles of axons (the long projections of neurons) that transmit signals between the brain, spinal cord, and the rest of the body. They play a vital role in both the central and peripheral nervous systems.
-
Stimuli: External or internal changes that provoke a response in an organism. This can include light, sound, temperature, or pain. When stimuli are detected by sensory receptors, they can trigger signals that are sent through nerves to the brain.
