Stereocilia Stairsteps: By Leonardo Andrade and Bechara Kachar, NIDCD/NIH    We can enjoy music and hear the city traffic because of clusters of specialized cilia (green) in the inner ear, called stereocilia. These actin-rich bundles protrude from the apical surface of hair cells lining the inner ear and vibrate in response to sound waves.

Myelinated nerves. Coloured scanning electron micrograph (SEM) of a section through the sciatic nerve, showing the myelinated nerve fibres (axons). Myelin (blue) is an insulating fatty layer that surrounds the nerve fibre (brown), increasing the speed at which nerve impulses travel. It is formed when Schwann cells wrap around the fibre, depositing layers of myelin between each coil. The outermost layer consists of the Schwann cell's cytoplasm and is known as the neurolemma or sheath of…
