Encyclopaedia Britannica, 11th Edition, Volume 4, Slice 4 "Bradford, William" to "Brequigny, Louis" The olfactory cell has also a long slender branch extending from its base through the bone into the skull cavity and connecting there with dendrites of nerve cells. Psychology A Study Of Mental Life When these "dendrites" touch, communication is established; when this contact is broken, it is non-existent. The Problems of Psychical Research Experiments and Theories in the Realm of the Supernormal The dendrites are comparatively large in diameter, branch freely, like the branches of a tree, and extend but a relatively short distance from the parent cell. The Mind and Its Education The dendrites increase greatly the surface of the cell-body, to which they are related in function. Physiology and Hygiene for Secondary Schools Fibres from white core of folium ending in molecular layer in connexion with the dendrites of the cells of Purkinje. Encyclopaedia Britannica, 11th Edition, Volume 4, Slice 4 "Bradford, William" to "Brequigny, Louis" The nerve cells remain small and their dendrites few and meager, because they have not received their normal amount of exercise through stimulation from the eye. Psychology A Study Of Mental Life If these theories be true, what, it may be asked, is the agency that causes the dendrites to contract or the neuroglia cells to expand? Scientific American Supplement, No. 1178, June 25, 1898 They reach a much greater distance from the cell body than the dendrites. The Mind and Its Education It is now known that the protoplasm in all parts of the neuron proper—cell-body, axis cylinder, and dendrites—has a grayish color, while the coverings of most of the fibers are white.

Encyclopaedia Britannica, 11th Edition, Volume 4, Slice 4 "Bradford, William" to "Brequigny, Louis" One view shows nerve cells and their dendrites, with only a few axons, while the other shows axons, outgoing and incoming, and some of their fine branches. Psychology A Study Of Mental Life Two miles farther, the bed of the river was formed by a felspathic rock, with beautiful dendrites. Journal of an Overland Expedition in Australia : from Moreton Bay to Port Essington, a distance of upwards of 3000 miles, during the years 1844-1845 Occasionally their antiquity is indicated not only by their colour but by superficial incrustations of carbonate of lime, or by dendrites formed of oxide of iron and manganese. The Student's Elements of Geology Faint indications of similar 'dendrites' were visible in a Roman skull from Siegburg; whilst other ancient skulls, which had lain for centuries in the earth, presented no trace of them. On Some Fossil Remains of Man Communication across a synapse is always in one direction, from end-brush to dendrites. Psychology A Study Of Mental Life Now here is a curious and significant fact: the dendrites are receiving organs, not transmitting; they pick up messages from the end-brushes across the synapse, but send out no messages to those end-brushes. Psychology A Study Of Mental Life It is made up of nerve cells and their dendrites, of the beginnings of axons issuing from these cells and of the terminations of incoming axons. Psychology A Study Of Mental Life Most nerve cells have two kinds of branches, called the axon and the dendrites. Psychology A Study Of Mental Life Imagine one view superimposed upon the other, and you get some idea of the intricate interweaving of axons and dendrites that occurs in the cortex.
