Inner ear hair cells. Coloured scanning electron micrograph (SEM) of sensory hair cells from the inner ear. These cells are surrounded by a fluid called endolymph. As sound enters the ear it causes waves to form in the endolymph, which in turn cause the hairs to move. The movement is converted to an electrical signal that is passed on to the brain. Each crescent-shaped arrangement of hairs lies atop a single cell.

skin cell

Coloured scanning electron micrograph SEM of a squamous cell on the surface of the skin. This is a flat, keratinised, dead cell. Squamous cells are continuously sloughed off and replaced with new cells from below.

bundle of nerves. 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. I must try to remember that my nerves are this beautiful, not just a series of ill-functioning, trouble-causing body parts.
