On the other hand, in some neurons, after severance of the axon from the rest of the cell (spinal motor cell), the whole nerve cell as well as the severed axon degenerates, and may eventually die and be removed.
A single long axon carries the nerve impulse away from the cell body.
There seems to be little doubt, notwithstanding, that one of the chief functions of the nerve cell is that of the propagation of a trophicj influence along its axon.
We found that Wnt signaling modulates neuronal connectivity by regulating axon behavior, dendritic arborization and central synaptogenesis.
Like all neurones, the sensory neuron has a cell body, an axon, dendrites and axon terminals.
