What are the main supportive components of the nervous system?

The main supportive components of the nervous system are neurons. Neurons are specialized cells that transmit information throughout the body through electrical and chemical signals. They are fundamental to the functioning of the nervous system, as they are responsible for processing and conveying sensory information, as well as coordinating responses and regulating bodily functions.

Additionally, neurons enable communication between different parts of the body, allowing for the complex interplay of actions and responses required for movement, sensation, and homeostasis. This makes them central to the nervous system's structure and function, distinguishing them clearly from supportive structures like muscles, tendons, and ligaments, which play roles in movement and structural integrity but do not actively participate in the signaling and processing functions of the nervous system.
