A ray appears diagonally, from top left to bottom middle. Medullary rays, also known as vascular rays or pith rays, are cellular structures found in some species of wood. They appear as radial planar structures, perpendicular to the growth rings, which are visible to the naked eye.
During secondary growth, cells of medullary rays, in a line (as seen in section; in three dimensions, it is a sheet) between neighbouring vascular bundles, become meristematic and form new interfascicular cambium (between vascular bundles).
This tissue system is present between the dermal tissue and forms the main bulk of the plant body. Parenchyma cells have thin primary walls and usually remain alive after they become mature. Parenchyma forms the "filler" tissue in the soft parts of plants, and is usually present in cortex, pericycle, pith, and medullary rays in primary stem and ...
common-names (gives the common names of the species; requires "include-common-names" parameter to be set in the {{Plant species table}} header template for the relevant column to be present) range-image (adds a range image)
All plant organs arise ultimately from cell divisions in the apical meristems, followed by cell expansion and differentiation. Primary growth gives rise to the apical part of many plants. The growth of nitrogen-fixing root nodules on legume plants such as soybean and pea is either determinate or indeterminate. Thus, soybean (or bean and Lotus ...
Medullary ray may refer to: Medullary ray (anatomy), the middle part of the Cortical lobule; Medullary ray (botany), characteristic radial sheets or ribbons extending ...
Creates a row in a wikitable for use in lists of plants in an area, such as at Endemic plants of the Chatham Islands. The table header and footer can be generated with {{Plant location table}} and {{Plant location table/end}}. Fields: Required image; binomial; authority-name; authority-year; range; reference; Optional
In anatomy, a medullary ray (Ferrein's pyramid) is the middle part of a cortical lobule (or renal lobule). Each consists of a group of nephrons in the renal cortex. [1] Their name is potentially misleading, as "medullary" refers to their destination, not their location. They travel perpendicular to the capsule, and extend from the cortex to the ...
