This article is about anatomy term. For other uses, see Plexus (disambiguation).
In neuroanatomy, a plexus (from the Latin term for "braid") is a branching network of vessels or nerves. The vessels may be blood vessels (veins, capillaries) or lymphatic vessels. The nerves are typically axons outside the central nervous system.
The standard plural form in English is plexuses.[1][2][3] Alternatively, the Latin plural plexūs may be used.
