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.
Synaptic Transmission. Introduction Neurons receive information from sensory organs, send information to motor organs, or share information with other neurons. The process of communicating information is very similar, whether it is to another neuron or to a muscle or gland cell.However, by far the largest number of neuronal connections is with other neurons. The rest of this tutorial therefore focuses on inter-neuronal communication.he transmission of information is accomplished in two ways: 1  Electrically: the neuron is directly adjacent to other neurons. 2  Chemically: there is a space (the synaptic cleft) between the axon terminus and the adjacent neuron.
