The thyroid and thymus are antagonistic, for the thyroid hastens differentiation, puberty and the coming of sexual maturity, while the thymus delays and retards them and prolongs the period of childhood.
It checked, perhaps, but it nowhere succeeded in stopping the slow but inevitable differentiation of province from province and nation from nation. The forces of transit that permitted the Roman imperialism and its partial successors to establish wide ascendancies, were not sufficient to carry the resultant unity beyond the political stage. There was unity, but not unification.
He makes a division into two stupors: Anergic Stupor and Delusional Stupor. When one examines his points of difference between these two types, it becomes clear that Newington really gave an excellent differentiation of benign and malignant stupor in fact, it is the only serious attempt at such discrimination prior to this present work.
A single bee, like a man, is a definitely constituted aggregate of cells, differing as a whole from Hydra only in the degree of differentiation exhibited by its constituent elements. Instead of a loose network of nerve-cells there is the far more complex nervous system whose evolution has been outlined in the sixth chapter.
We saw, in studying the embryonic development of each organ, that the human embryo follows the special lines of differentiation and construction that are only found otherwise in the Vertebrates. Within the limits of this vast stem we have followed, step by step, the development both of the body as a whole and of its various parts.
He saw clearly that this differentiation had been effected by playing off one military party against the other, or by dividing the same party against itself; and he saw clearly that opportunities for such measures had been furnished by subjecting the military leaders to constant contact with the Court nobility. Therefore, he determined to keep two aims always in view.
She was quite the person to take 'au grand serieux' the monstrous imaginations of Lady Byron's jealousy and to feel it on her conscience to make public report of them when she conceived that the time had come to do so. In Francis Parkman I knew much later than in some others a differentiation of the New England type which was not less characteristic.
The grading of the pupils in a class usually expresses this differentiation of the intelligence; and while the differences of industry or of mere memory and similar secondary features may sometimes interfere, it remains after all not difficult for an observant teacher to grade the pupils of his class, whom he knows well, according to their general intelligence.
Group after group of cells were set apart for one special duty after another, and the result was a larger and ever more complicated mass of cells, with a greater and greater differentiation among them. In this building of the machine there was no time when the machine was not active.
It is, therefore, to this vital sensation of deep or arrested respiration that the impressiveness of those objects is immediately due. The influence of the passion of love. Half-way between vital and social functions, lies the sexual instinct. If nature had solved the problem of reproduction without the differentiation of sex, our emotional life would have been radically different.
