What Messages from the body's tissue and sensory organs inward to the brain and spinal cord for processing?

Messages from the body's tissues and sensory organs are transmitted to the brain and spinal cord through sensory neurons. These neurons convert stimuli—such as touch, pain, temperature, and pressure—into electrical signals. These signals travel along afferent pathways to the central nervous system, where they are processed, interpreted, and integrated, allowing the body to respond appropriately to various environmental changes. This communication is crucial for maintaining homeostasis and facilitating reflex actions.
