Cell body Sentence Examples

Dendrite-A threadlike extension of the cytoplasm of a neuron that conducts electrical impulses toward the cell body of the neuron.

The daughter nuclei may have arrived at the anaphase stage, and have even gone the length of forming a nuclear membrane, without an equatorial depression having shown itself in the cell-body.

The neuron is described as having a cell body or perikaryon from which the cell branches - dendrites and axon - extend, and it is this perikaryon which, as its name implies, muscle produces lactic acids during activity, it has been suggested that acids are among the "fatigue substances" with which muscle poisons itself when deprived of circulating blood.

Although the cell body or perikaryon of the neuron, with its contained nucleus, is essential for the maintenance of the life of the cell branches, it has become recognized that the actual process and function of "conduction" in many neurons can, and does, go on without the cell body being directly concerned in the conduction.

This indicates that the conjunction between the conducting substance of the dendrons and that of the axon can be effected without the intermediation of the cell body.

But the proper nutrition of the conducting substance is indissolubly dependent on the cell branches being in continuity with the cell body and nucleus it contains.

The motor nerve cell body has a long fiber called an axon, which extends from the central nervous system to the muscles.

The cell body of a sensory nerve has two axons.

A single long axon carries the nerve impulse away from the cell body.

A neuron is composed of a central cell body with branches, called dendrites.

Where the axon leaves the cell body of a neuron is an area called the axon hillock.

The only evidence we have in pathology of living structures in which apparently a differentiation into cell-body and nucleus does not exist, is in the case of bacteria, but then there comes the question whether they may not possess chromatin distributed through their substance, in the form of metachromatic points, as is the case in some infusoria (Trachelocerca, Gruber).
