What's the difference between fenestra and fenestral?
Fenestra
Definition:
(n.) A small opening; esp., one of the apertures, closed by membranes, between the tympanum and internal ear.

(20) Diaphragmed fenestrae (DF) are sites of increased vascular permeability.
Fenestral
Definition:
(a.) Pertaining to a window or to windows.
(a.) Of or pertaining to a fenestra.
(n.) A casement or window sash, closed with cloth or paper instead of glass.
Example Sentences:
(1) The reinforcement portion of the surgical drape that contained the fenestration was segmented into four identical-appearing sections, two on each side of the fenestration.
(2) Numerous slender sarcotubules, originating from the A-band side terminal cisternae, extend obliquely or longitudinally and form oval or irregular shaped networks of various sizes in front of the A-band, then become continuous with the tiny mesh (fenestrated collar) in front of the H-band.
(3) These alterations include fenestration, widened intercellular junctions, increase in pinocytotic vesicles, and infolding of the luminal surface.
(4) This report is the first published demonstration of the existence of fenestrated capillaries in human parietal and rabbit diaphragmatic peritoneum.
(5) Only when fenestrations were employed did the irritation subside and disappear.
(6) In acute aortic dissection fenestration of the intimal flap may relieve thoracoabdominal malperfusion.
(7) Fenestrated endothelia have higher hydraulic conductivities and are more permeable to small ions and molecules than are continuous endothelia.
(8) Z and T tubules form interconnections with each other, but only T tubules form specific contacts with the sarcoplasmic reticulum, which in these fibers forms an extended and continuously fenestrated network.
(9) Surgical treatment remains controversial, and the options of cyst puncture, fenestration with or without hepatic resection, and liver transplantation are reviewed.
(10) Fenestrated capillaries were also found at the edge of the granulomas.
(11) The increased functional activity of the endothelium, thinner walls of capillaries and the appearnace of a greater amount of fenestrations against the background of the thyroid stimulation are likely to be factors contributing to penetration of non-hormonal iodine products (iodine tyrosines and products of incomplete hydrolysis of thyroglobulins) into the circulation, which can be observed under certain pathological conditions accompanied by increased thyrotropic stimulation--such as diffused toxic goiter and diffuse non-toxic goiter.
(12) The fenestration should be a true anomaly but at this point we do not have any suggestive clue for that.
(13) In an attempt to destroy selectively the affected peripheral vestibular labyrinth in patients with intractable vertigo as a result of Meniere's disease, a known quantity of streptomycin was introduced within the bony labyrinth following fenestration of the horizontal semicircular canal.
(14) The endothelium of these vascular segments reveals fenestrations and a high pinocytotic activity.
(15) The study demonstrates that where regenerative liver is capillarized, with replacement of fenestrated sinusoids, Kupffer cells are absent.
