The human body's intricate network of nerves relies heavily on four major nerve plexuses that distribute signals across various regions, ensuring coordinated movement and sensation. These nerve plexuses, including the cervical, brachial, lumbar, and sacral complexes, originate from the spinal cord and extend to the head, arms, and legs, playing a vital role in both voluntary and involuntary functions. This article delves into their anatomical structure and physiological significance, offering a detailed guide to understanding their contributions to the peripheral nervous system.
