"Mucus" Quotes from Famous Books



... and the anaesthesia are co-extensive. The intercostal muscles below the seat of the lesion and the abdominal muscles are paralysed. The respiratory movements are thus impeded, and, as the patient is unable to cough, mucus gathers in the air-passages and there is a tendency to broncho-pneumonia. As the patient is unable to aid defecation or to expel flatus by straining, the bowel is liable to become distended with faeces and gas, and the meteorism which results adds to the embarrassment of respiration ...

... to the first and second bicuspids. The close packing of the lower incisors may assist by preventing the retention of decaying fragments of food. Sexual selection may promote caries by favouring white teeth, which are more prone to decay than yellow ones. Acid vitiation of the mucus might account both for caries and (possibly) for the strange infertility of some inferior races ...

... ce manege, elles nageaient avec une molle lenteur vers les males et semblaient se complaire dans leur voisinage." After the male has won his bride, he makes a little disc of froth by blowing air and mucus out of his mouth. He then collects the fertilised ova, dropped by the female, in his mouth; and this caused M. Carbonnier much alarm, as he thought that they were going to be devoured. But the male soon deposits them in the disc of froth, afterwards guarding them, repairing ...

... he somewhat similar in less essential properties; thus the thin and saline discharge from the nostrils on going into the cold air of a frosty morning, which is owing to the deficient action of the absorbent vessels of the nostrils, is one species; and the viscid mucus discharged from the secerning vessels of the same membrane, when inflamed, is another species of the same genus, Catarrhus.

... either side of the uterus, and connected to it by two sensitive tubes. There ripens in one of these bodies each month a human baby-seed, which finds its way to the uterus through the little fallopian tube and is apparently lost in the debris of cells and mucus which, with the accompanying hemorrhage go to make up the menstrual flow. This continues from puberty to menopause, each gland alternatingly ripening its ovum, only to lose it in the periodical phenomenon of menstruation, which is seldom interrupted save by that still more wonderful ...

For two years past nearly every English paper, large and small, has systematically insulted Uncle Sam—has belched upon him all the feculent bile it could rake from its putrid bowels, all the moldy mucus it could snort from its beefy brain.

... exhausts the receptacle of the duct, a second (the venom being more or less mingled and diluted by the salivary secretion) is comparatively less fatal in results; and each successive repetition correspondingly inoffensive until finally nothing but pure mucus is ejected. Nevertheless, when thoroughly aroused, the reptile is enabled to constantly hurl a secretion, since both rage and hunger swell the glands to enormous size, and stimulate to extraordinary activity—a fortuitous circumstance to which many ...

... the stem is of lace-like structure, pure white, and its appearance suggests the silicious sponge so ornamental in collections, commonly known as Venus' basket. The drooping cap is also lacey with a network, and the spores drip mucus and then dry up, in the meantime spreading around a carrion-like, fetid smell. The Phallus, therefore, differs greatly in appearance from the other genera of the order when it is seen above ground, but if one is successful in finding it at an early stage, under the surface ...

... particles, which exhibit the first active movements in organic solutions. They vary in size from the one hundred-thousandth to the one twenty-thousandth of a second of an inch in diameter, and appear at first hardly more than moving specks of semi-translucent mucus. Indeed, Burdach calls them "primordial mucous layers." But they move, pulsate, swarm into colonies, and act as if they were guided, not by separate intelligence, but by some master-builder supervising the whole work ...

One of the peculiar features, as we shall find, when we come to describe cases, is, that the secretory function is ever after so changed in its character, that the gland which formerly secreted mucus, to lubricate the passages, now performs the same service with muco-carbon, and continues to do so during the remainder of the patient's life—even, as I have often seen, long after he has desisted from the occupation of a coal-miner. In fact, it constitutes a striking peculiarity of this disease, ...
