One of the first things that most designers forget about CSS descendant selectors is that they are flexible. When CSS defines a descendant, it doesn't care whether the tag in question is the direct child, the grandchild, or some great-great-great-descendant of the initial element.
From the retina, visual information passes onto the bipolar cells and then to the optic nerve's ganglion cells. The optic nerve, which begins at the retina, is the sole visual pathway to the brain. Light information is conveyed as an electrical action potential through the neurons.
1 Each branch is called a dendrite. 2  Dendrites receive information from other neurons or from sense organs. 3  The single long fiber that extends from the neuron is called an axon. 4  Axons send information to other neurons, to muscle cells, or to gland cells.5  What we call nerves are bundles of axons coming from many neurons.eurons receive information, integrate it, and pass it along. They communicate with one another, with cells in the sensory organs, and with muscles and glands. Each neuron has the same structure: 1  Each neuron has a soma, or cell body, which is the central area of the neuron.
