A prostrate, branching-stemmed, small-growing kind, very proliferous, with roots along the main stems; branchlets upright, five-angled, with slightly raised points, or tubercles, upon which are ten short hair-like spines, arranged in a star, and surrounding three or four central erect spines, all whitish and transparent.
A creeping, prostrate plant, with round stems as thick as a goose-quill, and attaching themselves to tree-trunks or other bodies by means of numerous adventitious roots, which spring from the under side of the stems. Surface of stem furrowed, and covered with numerous small clusters of short, hair-like, whitish spines.
It grows and flowers freely in an ordinary greenhouse, and would thrive in a sunny window if kept dry during the winter. A short, dumpy plant, with numerous tubercled ridges, bearing bunches of dark brown hair-like spines, which form a close network about the stem.
This fibrous construction became still more distinct to the light by adding some caustic alcali to the water; as the adhering mucus was first eroded, and the hair-like fibres remained floating in the vessel. Nor does the degree of transparency of the retina invalidate this evidence of its fibrous structure, since Leeuwenhoek has shewn, that the crystalline humour itself consists of fibres. Arc.
We have muscle cells, with long, thin bodies like pea-pods, who devote their lives to the business of contraction; thin, hair-like connective tissue cells, whose office is to form a tough tissue for binding the parts of the body together; bone cells, a trades-union of masons, whose life work it is to select and assimilate salts of lime for the upkeep of the joints and framework; hair, skin, and nail cells, in various shapes and sizes, all devoting themselves to the protection and ornamentation of the body; gland cells, who give their lives, a force of trained chemists, to the abstraction from the blood of those substances that are needed for digestion; blood cells, crowding their way through the arteries, some making regular deliveries of provisions to the other tenants, some soldierly fellows patrolling their beats to repel invading disease germs, some serving as humble scavengers; liver cells engaged in the menial service of living off the waste of other organs and at the same time converting it into such fluids as are required for digestion; windpipe and lung cells, whose heads are covered with stiff hairs, which the cell throughout its life waves incessantly to and fro; and, lastly, and most important and of greatest interest to us, brain and nerve cells, the brain cells constituting altogether the organ of objective intelligence, the instrument through which we are conscious of the external world, and the nerve cells serving as a living telegraph to relay information, from one part of the body to another, with the "swiftness of thought."
There you have it in a nutshell. The mucous membrane of the larynx and the bronchial tubes, to enlarge upon its duty for a moment, is endowed with very fine, hair-like processes called cilia, whose action is to waft secretions from the interior of the lungs outward.
Miss Lizzie was not fair. Emmy Lou did not reach home until dinner was long over. She had first to cover four slips of trial-paper and half a page in her book with upward strokes fine and hair-like, and downward strokes black and heavy. Emmy Lou ate her dinner alone. At supper she spoke. Emmy Lou generally spoke conclusions and, unless pressed, did not enter into the processes of her reasoning.
The protoplasm of Algae and Fungi becomes, under many circumstances, partially, or completely, freed from its woody case, and exhibits movements of its whole mass, or is propelled by the contractility of one, or more, hair-like prolongations of its body, which are called vibratile cilia.
His arms, as well as legs, were bowed in the most singular manner, and appeared to possess no flexibility whatever. To conceal this latter deficiency, which did not proceed from old age, he usually wore a wig formed of any hair-like material which presented itself occasionally the skin of a Spanish dog or American grizzly bear.
From the right ventricle arises one large vessel, the pulmonary artery, which soon divides into two branches of nearly equal size, one for the right lung, the other for the left. Each branch, having reached its lung, divides and subdivides again and again, until it ends in hair-like capillaries, which form a very fine network in every part of the lung.
