Neurons belonging to this class have each a well-defined cell-body and two axons, but no parts just like the dendrites of mon-axonic neurons.
The dendrites increase greatly the surface of the cell-body, to which they are related in function.
These consist of loose end-to-end unions of the fiber branches of certain neurons with the dendrites of other neurons.
Thus a disturbance at the distant ends of the dendrites causes a movement toward the cell-body and, reaching the cell-body, the disturbance is passed through it into the axon.
Fibres from white core of folium ending in molecular layer in connexion with the dendrites of the cells of Purkinje.
Smaller dendrites arise from the lateral and basal surfaces of these cells, but do not extend far from the body of the cell.
The fibres give rise to an abundant plexus of fibrils in the granular layer, and many reaching into the molecular layer ramify there, especially in the immediate neighbourhood of the dendrites of Purkinje's cells.
The cells of this layer are irregular in outline, and give off several dendrites branching into the surrounding grey matter.
The deep ends of these olfactory neurones having entered the central nervous organ come into contact with the dendrites of large neurones, called, from their shape, mitral.
They give off a number of short dendrites with claw-like endings, and a fine non-medullated neuraxon process.
Ramon y Cajal, on the other hand, believes that the neuroglia cells are contractile, and may expand so as to interpose their branches as insulating material between the synapses formed by the dendrites of the nerve cells.
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?
An impulse is supposed to travel normally only in one direction through a neuron, the dendrites being the receiving and the axon the discharging terminals.
The axon of each neuron ends in an elaborate series of fine branchings which lie in contact with the dendrites of another neuron, or in some cases with the body of the other cell (Fig.
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.
Both dendrites and axons are of diameter so small as to be invisible except under the microscope.
The axon of one neurone, through its end-brush, is in close contact with the dendrites of another neurone.
Its dendrites are short tree-like branches, while its axon is often several inches or even feet in length.
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.
The end-brush, when a nerve current reaches it from its own nerve cell, arouses the dendrites of the other neurone, and thus starts a nerve current running along those dendrites to their nerve cell and thence out along its axon.
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.
Brain function depends on dendrites and end-brushes, forming synapses in the cortex, and such minute structures make little impression on the total brain weight.
Well, we find the sensory axon, as it enters the cord, sending off a number of side branches, each of which terminates in an end-brush in synaptic connection with the dendrites of a motor nerve cell.
These incoming axons terminate in end-brushes and so form synapses with the dendrites of the local {50} nerve cells.
Imagine one view superimposed upon the other, and you get some idea of the intricate interweaving of axons and dendritesthat occurs in the cortex.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "dendrites" in a variety of sentences. We hope that you will now be able to make sentences using this word.
