Fibrils Sentence Examples
There is a special marginal nerve running round the edge of the mantle, but the connexion of this with the rest of the nervous system is not clear; probably it is merely another concentration of the diffused sub-ectodermal nervous fibrils.
The lophophore is supplied by yet a third nerve, the under arm-nerve, which is less clearly defined than the others, and resembles a moderate aggregation of the nerve fibrils, which seem everywhere to underlie the ectoderm, and which in a few cases are gathered up into nerves.
Then they develop .definite fibrils which differentiate into fibrous laminae forming a zone which shuts off the abscess from the healthy tissue and so prevents the further invasion and injurious effects of the microorganism.
It is from these cells that the fine fibrillar substance is formed, and from this stage onwards - eight to fifteen days - there is a steady increase in the new fibrils, giving more density to the new tissue.
As their fibrils become more developed they gradually form fibrous laminae which are laid down first in the deeper part of the wound.Advertisement
The fibrils of the outer coat also show the change to a less extent, while the degeneration very rarely spreads to the middle coat.
It is a retrogressive process producing characteristic changes in the fine connectivetissue fibrils.
The change appears to begin in the fibrils which lie between the circular muscle fibres of the middle coat of the smaller arterioles and extends both backwards and forwards along the vessels.
It spreads forwards, affecting the supporting fibres outside the epithelium of the capillaries, and then passes to the connective-tissue fibrils of the veins.
It is taken up from the interstices between the particles of soil exclusively by the finest subdivisions of the fibrils, and in many cases by the extremely delicate thread-like cells which project from them and which are known as root-hairs.Advertisement
Early autumn planting enables wounded parts of roots to be healed over, and to form fibrils, which will be ready in spring, when it is most required, to collect food for the plant.
All planters lay great stress on the preservation of the fibrils; the point principally disputed is to what extent they can with safety be allowed to be cut off in transplantation.
In the fibrils existing in the cell a sudden alteration of elasticity occurs, resulting in an increased tension on the points of attachment of the cell to the neighbouring elements of the tissue in which the cell is placed.
The pain is due to stretching of the nerve fibrils or compression of them by the turgid vessels in the swollen tissues.
By means of the stinging nettle-cells or nematocysts with which the tentacles are thickly covered, living organisms of various kinds are firmly held and at the same time paralysed or killed, and by means of longitudinal muscular fibrils formed from the cells of the ectoderm the tentacles are contracted and convey the food to the mouth.Advertisement
By means of circularly disposed muscular fibrils formed from the endoderm the tentacles can be protracted or thrust out after contraction.
Lots of these collagen fibrils are bound together to form collagen fibrils are bound together to form collagen fibers that easily can be seen with a light microscope.
Outside the cell, collagen molecules become aligned in parallel formations, and then they link up laterally to form fibrils.
Out of a whole day's work he had found only 2 fibrils, 1 of which was on the first grid.
February 1987 The CVL identifies scrapie-associated fibrils (SAFs) in some of the brain samples referred to it.Advertisement
Electron microscopy reveals that elastic fibers are composed of bundles of small fibrils approximately 11 nm in diameter embedded in an amorphous material.
Units of the sarcoplasmic reticulum surround the contractile fibrils in the interior of cardiac muscle cells.
In these disorders, normally soluble proteins fold abnormally and become insoluble fibrils that damage tissue.
Lots of these collagen fibrils are bound together to form collagen fibers that easily can be seen with a light microscope.
The cell wall is approximately 50% cellulose fibrils.Advertisement
The fat melts and cooks the protein fibrils in the muscle bundles without causing excessive amino acid breakdown.
This was interpreted as evidence of local disorder in the array of collagen fibrils that comprise the corneal stroma.
The chloroplast consists of two parts, a colorless ground substance, and a green coloring matter, which is contained either in the form of fibrils, or in more or less regular spherical masses, in the colorless ground-mass.
This is typified by the presence of intracytoplasmic protein inclusions composed largely of alpha-synuclein fibrils.
Evidence is not wanting, however, that the cytoplasm must be regarded as, fundamentally, a semifluid, homogeneous substance in which by its own activity, granules, vacuoles, fibrils, &c., can be formed as secondary structures.
