fibroelastic

The fibroelastic coat of the spleen invests the organ, and at the hilum is reflected inward upon the vessels in the form of sheaths.

Elastofibroma, also called elastofibroma dorsi, is an ill-defined fibroelastic tumor-like condition made up of enlarged and irregular elastic fibers.

"Forme fruste mitral regurgitation", mitral regurg due to fibroelastic deficiency with myxomatous changes (as opposed to fully formed degenerative changes seen in Barlow's disease).

The larger blood vessels (interlobar and arcuate arteries) show reduplication of internal elastic lamina along with fibrous thickening of the media (fibroelastic hyperplasia) and the subintima.

The dura mater outermost part, is composed of loosely arranged fibroelastic layer of cells, characterized by multiple interdigitating cell processes, no extracellular collagen and significant extracellular spaces.

The secretory epithelium is mainly pseudostratified, comprising tall columnar cells and basal cells which are supported by a fibroelastic stroma containing randomly orientated smooth muscle bundles.

From these sheaths, as well as from the inner surface of the fibroelastic coat, numerous small fibrous bands, the trabeculae of the spleen (or splenic trabeculae), emerge from all directions; these uniting, constitute the frame-work of the spleen.
