How does one nerve cell transmit the nerve impulse to another cell? Electron microscopy and other methods show that it does so by means of special extensions that deliver a squirt of transmitter ...

However, when Erbacher looked at skin tissue under the microscope, he noticed that nerve fibers did not just grow around skin cells but, to the whole team’s surprise, tunneled straight through them.

The nerve tract is filled with ring-shaped structures, indicating a transverse section of myelinated nerve fibers. (D) Electron microscopy ... neurons and Schwann cells. Myelin segments are ...

The entorhinal cortex (EC) plays a pivotal role in memory function and spatial navigation, connecting the hippocampus with the neocortex. The EC integrates a wide range of cortical and subcortical ...

The best light microscope can show details that are 0.2µm apart and need a magnification of roughly x1500 so that our eyes can see it - this allows us to see larger cell structures. Electron ...

Light microscopes use light and mirrors and can see things as small as 400 nanometers. This allows us to get down to the world of the cell ... a leaf surface under a scanning electron microscope.
