✯ Nerve cells and glial cells, coloured scanning electron micrograph (SEM). The nerve cells have small cell bodies (orange) and fine extensions called axons and dendrites (brown). The glial cells have large cell bodies (blue) with thicker extensions (pale green). Neurons are responsible for passing information around the central nervous system (CNS) and from the CNS to the rest of the body. Glial cells are nervous system cells that provide the neurons with structural support and protection-PIC1✯

Three neurons and human embryonic stem cells (via California Institute for Regenerative Medicine) Three neurons (red) derived from human embryonic stem cells (hESCs) as seen by a confocal microscope. Visible are neural cell bodies, complete with axons and dendrites (red), used for cell-to-cell communications, as well as undifferentiated hESCs (green).

The retina contains five classes of neurons: photoreceptors (purple), horizontal cells (yellow), bipolar neurons (green), amacrine cells (pink and blue), and ganglion cells (pink and blue). In this cross section of an adult mouse retina, only a subset of bipolar cells, “the ON bipolar cells” are visible by their expression of GFP (green). The pink and blue speckled striations at the bottom of the image mark the fiber layer, which contains the ganglion cell axons that will form the optic nerve.

Nerve cells. Coloured scanning electron micrograph (SEM) of nerve cells, known as neurones. Nerve cells occur in the brain, spinal cord, and in ganglia. Each nerve cell has a large cell body (brown) with several long processes extending from it. The processes usually consist of one thicker axon and several thinner branched dendrites. The dendrites collect information in the form of nerve impulses from other nerve cells and pass it to the cell body.
