An axon, or nerve fibre, is a long slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron's cell body or soma.
If just one single cell body gets into the axon study material, it will contaminate it with its own RNA, making it impossible to see what the axon's RNA reservoir looks like.
Dendrites receive input from many other neurons and carry those signals to the cell body. If stimulated enough, a neuron fires an action potential -- an electrical impulse that then stimulates other neurons.
In order to carry out the important task of communicating with other nerve cells, the fine branches of these nerve fibres and their ends, called synapses, must be regularly supplied with energy from the cell body.
When applied intramuscularly, BoNT blocks synaptic transmission at the neuromuscular junction and, in addition, is transported retrogradely to the motoneuron cell body and possibly also transcytosed to afferent synaptic terminals [13-16].
Each nerve cell consist of three main parts - the soma (cell body), an elongated axon, and several branching dendrites.
Astrocyte cell body volume was obtained during the counting procedures using an optical fractionator.
They usually displayed large cell body, long smooth dendrites running across all layers.
Samples are placed in the cell body along with an inert granular matrix.
The structure of the bristle base at its transition into the cell body will be important to resolve.
