Abstract:
Using the Golgi staining method with the modification suggested by Colonnier (J. Anat. 98:327, 1964), we have carried out a morphological study of the bipolar cells of the chicken and classified them into various morphological types. In the classification given we have described the existence of seven main groups of bipolar cells that differ in shape and spread of their dendritic network. In addition, within each of these groups we have taken into account other morphological features, such as the presence and position of Landolt' s club, the size of the dendritic field, the presence of an accessory dendritic process, the position of the perikaryon in the INL. The stratification of the axonal ending is demonstrated but cannot be related to the classification based on dendritic morphology that we have chosen.

Basic Characteristics of Cells
A living cell has a plasma membrane, a bilayer of lipids that separates the aqueous solution inside the cell called the cytoplasm from the outside environment.
Furthermore, a living cell possesses genetic information...

Water
The polarity of the water molecule and its resulting hydrogen bonding makes water a unique substance with special properties that are intimately tied to the processes of life. Life originally evolved in an aqueous environment, and most of an organism’s cellular chemistry and metabolism occur inside the aqueous contents of the cell’s cytoplasm. Special properties of water are its high heat capacity...
