MEDULLARY RAYS Meaning and
Definition
-
Medullary rays, also known as wood rays or pith rays, are structures found in the wood of woody plants. They are thin, ribbon-like tissues that radiate outward from the pith or the center of the stem, crossing the annual growth rings.
Medullary rays primarily function as a means of transport, allowing nutrients and fluids to move laterally through the plant. They run perpendicular to the grain of the wood and connect the central pith region with the outer bark.
These structures are composed of living cells and can vary in size, ranging from minimal visibility to several cell layers thick. Medullary rays are typically wider in hardwood trees compared to softwood trees.
In addition to their transport role, medullary rays also play a crucial role in the structural integrity of the wood. They provide strength and stability to the tree by connecting the different layers of wood and preventing separation. This property makes medullary rays significant in the production of high-quality lumber and timber.
Furthermore, medullary rays contribute to the aesthetic appeal of certain wood species. They give rise to distinct figures and patterns known as ray flecks, which are often sought-after characteristics in decorative woodworking.
In summary, medullary rays are thin, ribbon-like tissues that run across the grain of wood, connecting the center of the stem with the outer bark. They have transport functions, provide structural integrity, and contribute to the visual appeal of certain wood species.

Etymology of MEDULLARY RAYS
The word "medullary rays" has its etymology rooted in Latin and Greek.
The term "medullary" is derived from the Latin word "medulla", meaning "marrow" or "pith". In the context of medullary rays, it refers to the central pith-like tissue found in the stems and roots of plants.
The word "rays" comes from the Latin word "radius", which originally referred to a spoke on a wheel. In the case of medullary rays, it describes the radial arrangement of the tissue that extends from the pith to the outer layers of the stem or root.
Therefore, "medullary rays" collectively refers to the radial tissues extending from the central pith to the periphery of a stem or root in plants.
