The plant is easily recognized by its large, cup-shaped volva and cap, which is not smooth, as is usual in a species with a persistent membranous volva, more or less scaly with minute tufts of fibrils or tomentose hairs.
Its center is without any prominence or very bluntly prominent, and its surface is commonly very obscurely marked with innate fibrils or in small plants may have very small flocculose tufts or scales.
From the pileus not being hygrophanous, at the first smooth and at length torn into fibrils or squamulose, it might easily be taken for a species of Inoloma.
At this sweating stage, the germination begins; the fibrils of the radicle first sprout forth from the tip of every grain, and a white elevation appears, that soon separates into three or more radicles, which grow rapidly larger.
The muscular fibrils were friable and granular, and there was multiplication of the nuclei of the sarcolemma.
In ^Caulerpa^ the stability of the plant is secured by numerous fibrils which emanate from the interior of the cell, forming a spongy network of interlacing filaments.

Karyokinesis) or the nuclearfibrils of a cell; the nuclear part of a comet, etc.
This plumps the fibres, separates the fibrilsand kills the grease.
It is quite conceivable that a chrome leather could adsorb more tan than pelt, owing to the more complete isolation of the fibrils by the chrome tannage and to their being coated over by a more adsorbent gel.
The filets and fibrils of dust are exposed to sight in the flanks, and near the base of the great quartz-vein: we should never have been able to remove the barren upper capping.
A narrow gorge opens upon a semicircular hollow lined with ochraceous or ferruginous matter; in fact, part of the filon, which sends off fibrils in all directions.
These nerve-fibrils pass inward toward the centre, and enter ganglia, which in turn are in immediate connection with the great nerves of the balancers.
Nerve-fibrils emanating from the optic nerve enter the striated spindle at its lower extremity, and in this way nervously energize the visual rod.
The reddish-brown color is due to the coating of fibrils that covers the cap.
Caprinus means belonging to a goat; it is so called from the fibrils resembling goat's hair.
Gills somewhat sinuate, cuticle of the pileus silky, or bearing fibrils Inocybe.
The stem is solid, unequal, rooting, smooth, sometimes reticulated with black fibrils or scaly.
Probably the contraction of these fibrils serves to raise the opercular rods and hence to allow the exit of the endoplasm through the pores which lie between these opercular rhabdillae (compare s 59).
It therefore seems probable that special nerve-fibrils are set apart for the temperature-sense; but of the manner in which these fibrils terminate little or nothing is known.
As in Carcinus, described by Bethe, the optic tract enters the mesal side of the globulus and splits up into smaller and smaller parts, and is at last lost in the minute network of fibrils and supporting substance.
Nerve cells near each other in the brain fibrils are shown.
Probably most of the conducting fibrils leave at or near the termination of the thicker part of the fiber.
Special cells of the skin have been modified into neuro-epithelial cells, having sensory hairs protruding from them and nerve-fibrils running from their bases.
The muscular fibrils of a jelly-fish are mostly isolated or parallel in bands, rarely in compact well-defined bundles.
Here the sensory cells of feeling and their nerve fibrils multiply.
But there are also nerve-fibrils connecting the different ganglion cells, so that they may act in unison.
In the genus Inocybe there is a universal veil which is fibrillose in character, and more or less closely joined with the cuticle of the pileus, and the surface of the pileus is therefore marked with fibrils or is more or less scaly.
This genus is distinguished by the silky fibrilose covering of the cap, which never has a distinct pellicle, and by the veil which is lasting and of like nature to the fibrils of the cap.
There are sometimes fibrils which adhere to the margin of the cap, the remains of the veil.
Fibrils from these ganglia were seen to join the cranial and spinal nerve fibrils and to accompany them everywhere, but what special function they subserved was long a mere matter of conjecture and led to many absurd speculations.
Under proper stimulation the ends of the fibrils reach out, come in contact with other end fibrils of other cells, and conduct their destined impulse.
Now for the first time it became possible to trace the cellular prolongations definitely to their termini, for the finer fibrils had not been rendered visible by any previous method of treatment.
Golgi himself proved that the set of fibrils known as protoplasmic prolongations terminate by free extremities, and have no direct connection with any cell save the one from which they spring.
The fibres give rise to an abundant plexus of fibrils in the granular layer, and many reaching into the molecular layer ramify there, especially in the immediate neighbourhood of the dendrites of Purkinje's cells.
A network of nervous fibrils should be studied in the cornea.
One leg should be hardened in a straight position so as to fix the fibrils in the fully extended position, another should be bent up so as to get specimens of relaxed fibrils.
These fibrils are so easily excited by electricity as to denote an essential similarity of build.
Analogous in operation are the fibrils of the eye which respond to light-waves of various length and intensities.
In an arid plain of Arizona a vine, in ground parched and dry, goes downward so far, and spreads its fibrils so much abroad, as soon to show ten times as much growth below the drifting sands as above them.
Both the columnar layers of the eel and the fibrils of human muscle are affected in the same way by strychnine and by an allied substance, curare.
The characteristics of this eel have their homologies in the human body; in the muscles which bend the fore-arm, for example, are nearly a million delicate fibrils comparable in structure with the columnar organs of the gymnotus.
Footnote 493: The horny fibres are mesoblastic products; they are formed, in the first instance, as extremely delicate fibrils on the inner side of the membrane separating the epiblast from the mesoblast.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "fibrils" in a variety of sentences. We hope that you will now be able to make sentences using this word.
