What connection between cells tissue and organs in the nervous system?

In the nervous system, cells, tissues, and organs are interconnected in a hierarchical structure. Neurons, the primary cells of the nervous system, group together to form nervous tissue, which is responsible for transmitting signals throughout the body. This nervous tissue then organizes into larger structures, such as the brain and spinal cord, which serve as organs that process and relay information. Together, these components enable the nervous system to coordinate bodily functions and respond to environmental stimuli.
