How Do Cells Work Together?
... Many cells have special structures that help them in their work. Examples: Muscle cells have long fibers made of protein. Lung airway cells have waving hair-like structures called cilia. They sweep germs and dirt out of the airways. Red blood cells are round discs. The shape of the cells help t ...

Subventricular zone
The subventricular zone (SVZ) is a paired brain structure situated throughout the lateral walls of the lateral ventricles. It is composed of four distinct layers of variable thickness and cell density, as well as cellular composition. Along with the dentate gyrus of the hippocampus, the SVZ is one of two places where neurogenesis has been found to occur in the adult mammalian brain.
