Neuron Tufted

Neuronal bundles are present in lower chordates, higher mollusks and many sponges. A neuronal bundle is a tissue of the body. These structures have different origins depending on the class of living organism, that is, a sponge has one neuroglial system that communicates with a single process of a bundle neuron (the so-called effector), while in a mollusk such structures are more similar to simple nerve cells.
