Developing nerve cells...I just cannot get over the marvel of the making of our bodies...

Developing nerve cells Torsten Wittmann, University of California, San Francisco These developing mouse nerve cells have a nucleus (yellow).

Myelinated nerves. A section through myelinated nerve fibres and Schwann cells.Myelin (green) is an insulating fatty layer that surrounds the nerve fibre (axon, black), increasing the speed at which nerve impulses travel.

Golgi apparatus of eukaryotic cells functions in protein synthesis. I loved my molecular biology class and love this photo. Now, how to incorporate cell structure and cellular functions for my class?

Axones nerviosos - A cross section of a bundle of nerve fibers.  Axons (orange) are wrapped in myelin (purple); an extension of the membrane of glial cells.  Myelin has high lipid content, and acts to insulate the axons, causing them to transmit nerve impulses much faster.

Neuron and Astrocyte by Dennis Kunkel; "Neurons...are the basic functioning components of the brain. ..Chemical and electrical activity between neurons allows us to perform all our actions and shapes our thoughts...Here a neuron (orange) is shown with a supporting glial cell...researchers are finding evidence that a category of glial cells, termed astrocytes, play an active role in brain function by promoting the activity of neurons."  -- Dennis Kunkel
