Nerve cells, or neurons, can range from .004 millimeters to .1 millimeters in diameter. Their length can be anywhere from a fraction of an inch to several feet long, depending on nerve cell type. More »

Nerve cells, or neurons, receive electrochemical signals, process them and transmit them to other cells. Most often, these are other neurons, but nerve cells signal muscle cells and other active cells of the body as well... More »

A nerve cell has several adaptations that allow it to carry out needed functions, such as its myelin sheath, projections and divisions, and its extremely long length. Nerve cells are also known as neurons. There are bill... More »

Nerve cells, or (neurons, comprise the nervous system. It is the job of these specialized cells to transmit information throughout the body to enable it to function. More »

The primary limitation on the size to which a single cell can grow is a mathematical principle called the surface to volume ratio. As the size of a three-dimensional object grows, its volume increases more rapidly than i... More »

The size of a cell is limited by its surface area to volume ratio. As cells grow larger in volume, their surface area decreases and their ability to diffuse compounds in and out of the cell decreases as well. More »
