Nervation is the anatomical term for the arrangement of veins or nerves in leaves, wings or other membranes. The spelling of "nervation" is based on the root word "nerv", which means "nerve". The pronunciation is /nɜːrˈveɪʃən/ or ner-vey-shuh n. It is derived from the French word "nervation" which also means "the arrangement of veins." The accurate spelling of anatomical terms is crucial for clarity and precision in medical and scientific communication.
Nervation refers to the arrangement of veins or nerve fibers within a structure, particularly in biological organisms. It describes the system or pattern of branching and distribution of veins or nerves, which play a crucial role in the transportation of fluids or information throughout the organism.
In plants, nervation specifically describes the arrangement and patterning of veins in leaves. This intricate network of veins provides structural support and serves as a conduit for the transport of water, nutrients, and photosynthetic products. Different plants exhibit distinct nervation patterns, such as parallel, reticulate (net-like), dichotomously branched, or palmate (diverging from a common point). These patterns can aid in plant identification and classification.
In animals, nervation primarily refers to the arrangement of nerves within organs, tissues, or body parts. Nerves transmit electrical impulses that are vital for coordinating various physiological processes, sensing stimuli, and controlling movements. Nervation patterns can differ based on the function and anatomy of a particular organ or tissue. For example, in the eye, the nervation pattern includes the distribution of nerves in the retina, allowing for visual perception.
Overall, nervation is a term used to describe the intricate arrangement, branching, and distribution of veins or nerves within biological structures. Its study helps biologists and anatomists better understand the organization and function of the vascular and nervous systems in living organisms.

The word "nervation" has its origins in Latin. It comes from the Latin word "nervus", meaning "sinew" or "string" or "nerve". The suffix "-ation" is a nominal suffix in English that denotes an action or process. Therefore, "nervation" refers to the process or action of forming or arranging veins or nerves, particularly in leaves or insect wings.
