👉 The undertake fluid, also known as the central nervous system (CNS), is a vital biological network composed of the brain and spinal cord. It serves as the body's control center, managing sensory input, processing information, and coordinating motor output. This intricate system of neurons and supporting cells facilitates communication between different parts of the body, allowing for thought, emotion, memory, and voluntary movement. The CNS integrates internal and external stimuli, enabling responses to the environment and maintaining homeostasis, which is essential for survival and overall bodily function.
