Definition & Meaning of "plexus"

What is a "plexus"?

A plexus is a complex network of nerves found within the human body. It is formed by the interweaving and branching of multiple nerves, creating a web-like structure. The plexus serves as a vital connection point for transmitting signals and information between various parts of the body. One prominent example is the brachial plexus, located in the shoulder region, which supplies the nerves that control movements and sensations in the upper limbs. Another well-known plexus is the solar plexus, located in the abdominal region, which plays a role in regulating the function of internal organs. The intricate nature of the plexus allows for the efficient distribution of nerve impulses, enabling coordinated movements, sensory perception, and overall bodily functions.
