Stomach cilia. Coloured transmission electron micrograph (TEM) of a section through the brush border lining in the stomach wall of a house mouse (Mus musculus), showing the cilia (hair-like) that cover its surface. Here, the transition zone (green) can be seen between the basal body (purple) and axoneme (orange) of one of the cilia. The basal body is the site of growth for the microtubules that make up the axoneme - the inner core of each cilium that provides support and facilitates movement
