Usage examples of dendrite.
However, in the living system it happens that the nerve impulse in the dendrites virtually always travels toward the cell body, whereas in the axon it travels away from the cell body.
The acetylcholine liberated at the axon endings of one nerve will affect the dendrites, or even the cell body itself, across the synapse and initiate a new nerve impulse there.
A neuron consists of a soma, which is its central cell body, and an axon and dendrites.
The axon and dendrites are thin branching tubes that form tree-like structures coming out of the soma.
Except for the blood and such roaming cells as histiocytes, every other cell in the body that carries our little friend is probably connected by very fine filaments, sort of like the axons and dendrites connecting nerve cells of the brain.
Thus any change in the structure of dendrites and the location of the synapses on them can change the neurophysiological relations of pre and postsynaptic cells.
Some of these synapses are on the shafts of the dendrites, others are attached to the tiny spines which stud the dendritic surface and which can be seen in Figure 10.
Changes in synaptic connectivity between one neuron and another as a result of learning along hebbian lines might involve the dendrites increasing in length, or changing in branching pattern, or the numbers of their spines might alter.
He then selected a particular class of neurons, recognizable by their long axons, measured the length of each dendritic branch and counted the spines on each, which he then calculated as number of spines per um - that is, millionth of a metre - of dendrite.
Neurons are concentrated in clusters with short interconnecting axons and dendrites between the cells of the group and defined nerve tracts leading in and out.
Nonetheless the eye of art and experience can interpret the electron micrographic chaos to pick out individual synapses, cell bodies, axons and dendrites and measure them.
Branching from the cell body are the dendrites, studded with small spines.
Running away from the cell body is the axon, which branches into an array of processes each ending in synaptic terminals at which contact is made with the dendrites or cell bodies of other neurons.
Using the light microscope, one cannot see individual synapses, but it is possible to stain individual neurons and analyse the structure of their dendrites, hence picking up possible changes.
The surface of each of the dendrites which branch out from the neuronal cell body is covered with synapses - perhaps up to ten thousand in all - arising from the other neurons which thus make contact with them.
